Special emphasis is made on the 'intrinsic' development of the field, including rapid progress of the low-T, Josephson junction technology and recent invention of several important devices. In the near future, these developments promise the advent of several outstanding electronic devices which would be of practical value, despite the need for helium cooling. Against this background, introduction of the high-T, superconductors in the foreseeable future will probably be restricted to the few simplest electronic devices and components. superconductor review

Albrecht1991 199101 J Appl Phys, new frequency modulation (FM) technique has been demonstrated which ennances the sensitivity of attractive mode force microscopy by an order of magnitude or more. Increased sensitivity is made possible by operating in a moderate vacuum ( less than 10 - 5 Torr), which increases the Q of the vibrating cantilever. In the FM technique, the cantilever serves as the frequency determining element of an oscillator. Force gradients acting on the cantilever cause instantaneous frequency modulation of the oscillator output, which is demodulated with a FM detector. Unlike conventional slope detection, the FM technique offers increased sensitivity through increased Q without restricting system bandwidth. fm sensitivity IBM Almaden with Rugar

The feedback is designed to reduce the effective resonance quality factor of the cantilever. The resultant regulation of the cantilever motion is shown to improve the measurement dynamics in atomic force microscopy, without signiticantly degrading the signal to noise ratio. cantilever control

Chen1994 199401 A variational method is used to calculate the deflection and the fundamental and harmonic resonance frequencies of commercial V-shaped and rectangular atomic force microscopy cantilevers. The effective mass of V shaped cantilevers is roughly half that calculated for the equivalent rectangular cantilevers. Damping by environmental gases, including air, nitrogen, argon, and helium, affects the frequency of maximum response and to a much greater degree the quality factor Q. Helium has the lowest viscosity, resulting in the highest Q, and thus provides the best sensitivity in noncontact force microscopy. Damping in liquids is dominated by an increase in effective mass of the cantilever due to an added mass of the liquid being dragged with that cantilever. at DOE in oakridge cantilever parameters

Bergh1996 199601 We consider the effects of close coupling between magnetic spin systems and oscillator detectors. The scaling of present experiments using both mechanical and electrical oscillator detectors for single-spin detection is examined. We show how nonlinear interactions ignored in previous descriptions may dominate the detector response in single-spin schemes using mechanical detectors. From a generalized form of the coupled Bloch equations, the difference between mechanical and electrical oscillator detection can be readily appreciated. Numerical solution of the coupled system using reasonable experimental parameters shows that complex dynamics may be observed in the single-spin detection scheme when the detector and the spin system are strongly coupled. The interpretation of spin system data obtained from the motion of a mechanical oscillator will require understanding of these detector effects. oscillator theory

The position is obtained with a precision lower than 10 pm in the range of a hundred micrometers and a bandwidth of 1 kHz. All the parameters of this system can be accurately and easily determined. The knowledge of an analytical form of the transient response of the actuator makes the calibration of the position sensor needless. The direct measurement of the position of the magnet gives entirely reliable results. This actuator could be, for example, applied to atomic force microscopy where a good precision in displacement is required to get force/distance curves or surface images. piezo positioner

Alignability of this sensor package is defined and calculated, taking into account the coupling efficiency and effects of various misalignments. Guidelines for making the package so that the fiber-optic sensor works more efficiently are developed from our calculations. optic sensors

The method used to analyze force detection may be extended to the case of weak classical forces with arbitrary time dependence, including nonstationary and impulsive signals. sql measurement

The distance dependence of the noise spectrum of free cantilever oscillations, of the resonance frequency, and of the damping coefficient were investigated under ultrahigh vacuum conditions. An analytic expression for the damping coefficient of a metallic tip-sample system was obtained on the basis of fluctuating electrodynamics. Our calculation is in good agreement with experimental data. afm noise

Gauthier1999 199901 Classical atomic force microscopes use a soft cantilever spring to convert the interaction between a tip and a surface into a displacement. This leads to indirect force measurement and instability in the case of attractive forces. We have developed a new kind of force sensor to overcome these limitations. The principle is to place a tip glued on a small magnet in levitation in a magnetic field. A servo-loop ensures the stability of the equilibrium in the vertical direction and allows the measurement of forces. It is monitored by an optical sensor that measures continuously the actual position of the tip with a sensitivity of 10 pm. With such a device it is possible to obtain the van der Waals attraction up to the molecular contact without jump. A digital signal processing board stops the approach of the tip just before contact to prevent any deterioration of the surface during the measurement. This allows images of soft and brittle surfaces, such as a micro-filtration membrane. cantilever tips

Genolet1999 199901 with Vettiger at IBM, and someone at Novartis, A new probe made entirely of plastic material has been developed for scanning probe microscopy. Using a polymer for the cantilever facilitates the realization of mechanical properties that are difficult to achieve with classical silicon technology. The new cantilever and tip presented here are made of an epoxy-based photoplastic. The fabrication process is a simple batch process in which the integrated tip and the lever are defined in one photolithography step. The simplicity of the fabrication step, the use of a polymer as material, and the ability to reuse the silicon mold lead to a soft low-cost probe for scanning force microscopy. Imaging soft condensed matter with photoplastic levers, which uses laser beam deflection sensing, exhibits a resolution that compares well with that of commercially available silicon cantilevers. cantilever fabrication

Imry1999 199901 with Landauer at the IBM Watson Center, Electric current flow, in transport theory, has usually been viewed as the response to an applied electric field. Alternatively, current flow can be viewed as a consequence of the injection of carriers at contacts and their probability of reaching the other end. This approach has proven to be particularly useful for the small samples made by modern microelectronic techniques. The approach, some of its results, and related issues are described, but without an attempt to cover all the active subtopics in this field. electron theory

Jakeman1999 199901 Statistics of a telegraph signal, Equations are derived which describe the time evolution of the probability density and corresponding characteristic function of a telegraph signal which has passed through a detuned Lorentzian filter. A closed form expression for the characteristic function is obtained for the tuned case and the predicted joint statistics and correlation properties are reviewed in the context of earlier results. Low order correlation properties for the more general detuned case are calculated. It is shown that the stationary single interval statistics can be generated by a random phasor moving in a space of fractional dimensions and that a simple transform of variable leads to distributions which are stable in this space. qm signals

Lloyd199908 199908 obituary for Landauer, It is well known that scientific progress requires intellect. Less advertised is science's need for conscience. Intellect creates new ideas; conscience examines them for consistency and correctness. In other words, a scientific field requires not only head but heart as well. Rolf Landauer was both head and heart to the field of physics of information. He died of cancer on 27 April this year at the age of 72. Landauer based his research on a simple rule: information is physical. That is, information is registered by physical systems such as strands of DNA, neurons and transistors; in turn, the ways in which systems such as cells, brains and computers can process information is governed by the laws of physics. information history

Picinboo199911 199911 IEEE, Polyspectra are related to Fourier transforms of moment or cumulant functions of any order of random signals. They play an important role in many problems of signal analysis and processing. However, there are only a few statistical models giving explicitly the expression of polyspectra. Ordered signals are signals for which the explicit expression of the moment functions requires that the time instants appearing in these moments are put in an increasing order. There are many examples of such signals, the best known being the random telegraph signal constructed from a Poisson process. Some of these examples are presented and analyzed. The origin of the ordering structure is related with the point that real time is an oriented variable making a difference between past and future. This especially appears in Markov processes. The calculation of polyspectra is difficult because ordering is not adapted to Fourier analysis. By an appropriate grouping of various terms, the explicit expression of spectral moment functions is obtained. It shows in particular that many ordered signals present a normal density on the normal manifolds of the frequency domain and another contribution on the stationary manifold that is explicitly calculated. The analysis of the structure of this expression allows us to discuss some relationships with normal distribution, central limit theorem, and time reversibility. information theory

Garcia200005 200001 We discuss the stability of the tip motion in dynamic atomic force microscopy. A nonlinear dynamics analysis shows that the tip's phase space is divided in two basins of attraction. A phase space diagram dominated by either basin of attraction implies a stable motion while a substantial contribution from both basins is associated with instabilities. Because the dominance of a given basin of attraction depends on the tip surface interaction potential and separation, stable and unstable motions are intrinsic features of an oscillating tip near or in intermittent contact with a surface. afm oscillators

To overcome the van der Waals and magnetic dipole-dipole interactions, the particles were stabilized with hydrophobic amines, phosphines, carboxylates and/or polymers. Depending on the preparation parameters, our particles had either bcc or E-Co crystalline structures. Using MPD with magnetic fields up to 1 T, it was possible to create two-dimensional (2-D) arrays of near-perfect symmetry up to 1 um^2 in size on various substrates, e.g. carbon-coated copper grids, silicon, or glass. Growth of the 2-D crystal was shown to be dependent on the direction of the applied external magnetic field. Three-dimensional (3-D) crystals could be created by increasing the magnetic field strength up to 6 T. crystal structure

Jedema2001 200101 Finding a means to generate, control and use spin-polarized currents represents an important challenge for spin-based electronics, or 'spintronics'. Spin currents and the associated phenomenon of spin accumulation can be realized by driving a current from a ferromagnetic electrode into a non-magnetic metal or semiconductor. This was first demonstrated over 15 years ago in a spin injection experiment4 on a single crystal aluminium bar at temperatures below 77 K. Recent experiments5+-8 have demonstrated successful optical detection of spin injection in semiconductors, using either optical injection by circularly polarized light or electrical injection from a magnetic semiconductor.However, it has not been possible to achieve fully electrical spin injection and detection at room temperature. Here we report room-temperature electrical injection and detection of spin currents and observe spin accumulation in an all-metal lateral mesoscopic spin valve, where ferromagnetic electrodes are used to drive a spin-polarized current into crossed copper strips. We anticipate that larger signals should be obtainable by optimizing the choice of materials and device geometry. spin injection

Thus, the pseudogap phenomenon can be caused by an inhomogeneity of the metallic phase. As a result, the critical temperature is spatially dependent. Various types of nonuniform structure are described inhomogeneous carrier distribution, nonuniform distribution of pair breakers!.

The relative increase in spin-coherent injection is up to 500 percent in the biased structures, and up to 4,000 percent when p-n junctions are used to impose a built-in bias. spin injection

Kawakatsu200206 200206 An atomic force microscope for nanocantilevers measuring from a few 100 nm to a few mm in length was implemented. The natural frequencies of the nanocantilevers lie in the range of 1 MHz to 1 GHz, and optical detection schemes adapted to their size and frequency range was selected. A helium neon laser with a beat frequency of 890 MHz was used as the laser source. The beat was shifted to 1090 MHz by an acousto-optical-modulator, and used as the carrier for heterodyne laser Doppler measurement. This enabled velocity measurement up to around 100 MHz. The probe beam of the Doppler interferometer was guided to the nanocantilever by a single mode polarization-maintaining optical fiber terminated by a collimating lens, a quarter wave plate, and a focusing lens. Reflected light was collected by the same optics and mixed with the reference beam. Self-excitation of the nanocantilever at its lowest natural frequency was implemented for an amplitude of 1 nmp-p at 36 MHz. The Q factor of the cantilever was 8000. Noise effective amplitude of the Doppler interferometer was smaller than 10 pmp-p above 10 MHz. Frequency detection was possible for a nanowire measuring 100 nm in width. afm cantilevers

The degree of oscillations synchronization with external harmonic signal is calculated as a function of feedback strength, taking into account available bandwidth and coupling to environment. The feedback can efficiently suppress the dephasing of oscillations if the qubit coupling to the detector is stronger than the coupling to the environment. qm control

By using a single-electron transistor to detect the charge, we calculate that a significantly higher displacement sensitivity can be achieved than by using capacitive displacement sensing, primarily due to the strong piezoelectric coupling strength. We estimate a displacement sensitivity of order 10^-17 m/Hz^1/2 for a 1 GHz GaAs resonator. Our model solves the coupled electromechanical response self-consistently, including the effects of both dissipative and reactive electronic circuit elements on the resonator behavior. piezo transistor

D'Allesandro2003a 200301 On Quantum State Observability and Measurement, We consider the problem of determining the state of a quantum system given one or more readings of the expectation value of an observable. The system is assumed to be a finite dimensional quantum control system for which we can influence the dynamics by generating all the unitary evolutions in a Lie group. We investigate to what extent, by an appropriate sequence of evolutions and measurements, we can obtain information on the initial state of the system. We present a system theoretic viewpoint of this problem in that we study the observability of the system. qm measurement

We give conditions for controllability and observability and characterize the classes of equivalent models which have the same input-output behavior. The analysis is motivated by the recent interest in three level systems in quantum information theory and quantum cryptography as well as by the problem of modeling molecular magnets as spin networks. qm systems

Ghose2003 200301 Continuous observation of a quantum system yields a measurement record that faithfully reproduces the classically predicted trajectory provided that the measurement is sufficiently strong to localize the state in phase space but weak enough that quantum backaction noise is negligible. We investigate the conditions under which classical dynamics emerges, via continuous position measurement, for a particle moving in a harmonic well with its position coupled to internal spin. As a consequence of this coupling we find that classical dynamics emerges only when the position and spin actions are both large compared. These conditions are quantified by placing bounds on the size of the covariance matrix which describes the delocalized quantum coherence over extended regions of phase space. From this result it follows that a mixed quantum-classical regime (where one subsystem can be treated classically and the other not) does not exist for a continuously observed spin 1/2 particle. When the conditions for classicallity are satisfied (in the large-spin limit), the quantum trajectories reproduce both the classical periodic orbits as well as the classically chaotic phase space regions. As a quantitative test of this convergence we compute the largest Lyapunov exponent directly from the measured quantum trajectories and show that it agrees with the classical value. qm measurement

Hopkins2003 200301 with Habib and Schwab, Feedback cooling of a nanomechanical resonator, Cooled, low-loss nanomechanical resonators o er the prospect of directly observing the quantum dynamics of mesoscopic systems. However, the present state of the art requires cooling down to the milliKelvin regime in order to observe quantum e ects. Here we present an active feedback strategy based on continuous observation of the resonator position for the purpose of obtaining these low temperatures. In addition, we apply this to an experimentally realizable configuration, where the position monitoring is carried out by a single-electron transistor. Our estimates indicate that with current technology this technique is likely to bring the required low temperatures within reach. oscillator control

Swedlow2003 200301 Part of a review collection introduced by Reudi Abersold of the ISB, Swedlow identifies that biological imaging is quantitative, and hence bioinformatics is important. They are developing the Open Microscopy Environment (OME) to consistently record the varieties of data generated by different sample preparations, different imaging devices and methodologies, and different image deconvolution. XML is used to tag each piece of data, creating files out of a central, relational database. Modules representing linked investigative paths independently communicate with the database to generate XML files whose semantic content they hope will be complete and founded in consistency. Data analysis and interpretation are challenges, but the solution by informatics is equally a solution by community. This solution outlines the many solutions that will continue to emerge as a listable property of this effort, and one we prospectively hope has enduring value. biology classification

Ahn2003 200302 preprint, We show that quantum feedback control can be used as a quantum error correction process for errors induced by weak continuous measurement. In particular, when the error model is restricted to one, perfectly measured, error channel per physical qubit, quantum feedback can act to perfectly protect a stabilizer codespace. Using the stabilizer formalism we derive an explicit scheme, involving feedback and an additional constant Hamiltonian, to protect an (n - 1)-qubit logical state encoded in n physical qubits. qm control Caltech with Milburn

Eisert2004 200401 We study arrays of mechanical oscillators in the quantum domain and demonstrate how the motions of distant oscillators can be entangled without the need for control of individual oscillators and without a direct interaction between them. These oscillators are thought of as being members of an array of nanoelectromechanical resonators with a voltage being applicable between neighboring resonators. Sudden nonadiabatic switching of the interaction results in a squeezing of the states of the mechanical oscillators, leading to an entanglement transport in chains of mechanical oscillators.We discuss spatial dimensions, Q factors, temperatures and decoherence sources in some detail, and find a distinct robustness of the entanglement in the canonical coordinates in such a scheme.We also briefly discuss the challenging aspect of detection of the generated entanglement.

The mass-induced resonance frequency shifts by these adsorbates were then measured to ascertain a mass sensitivity of 2.53x10^-18g. In these initial measurements, this sensitivity is limited by the noise in the NEMS displacement transducer; the ultimate, limits of the technique are set by fundamental phase noise processes.

Gupta2004 200401 This article describes a surface micromachined cantilever beam-based resonator for biological sensing applications. The study used a novel microfabrication technique of merged epitaxial lateral overgrowth (MELO) and chemical mechanical polishing (CMP) to fabricate thin, low stress, single-crystal silicon cantilever beams. The vibration spectra of the cantilever beams, excited by thermal and ambient noise, was measured in air using a Dimension 3100 Series scanning probe microscope (SPM), and in certain cases, a Polytec MSV300 laser Doppler vibrometer. The sensors were used to detect the mass of Listeria innocua bacteria by applying increasing concentration of bacteria suspension on the same cantilever beams and measuring the resonant frequency changes in air. Cantilever beams were also used to detect the mass of proteins such as Bovine Serum Albumin (BSA) and antibodies for Listeria that were attached to the cantileverÕs surfaces by physical adsorption; following which they were used to capture and detect the mass of the bacterial cells on the functionalized cantilever beam surfacesÕ. The effects of critical point drying of the proteins were evaluated and the results indicate that the functionality of the antibodies was not reduced once rehydrated after critical point drying. The developed biosensor is capable of rapid and ultrasensitive detection of bacteria and promises significant potential for the enhancement of microbiological research and diagnostics. cantilever sensors

The reduction of these ideas to practice has been limited by a lack of practical experimental tools. Here we describe a modular design for DNA routing genes, and routing machinery made from oligonucleotides and commercially available chromatography resins. The routing machinery partitions nanomole quantities of DNA into physically distinct subpools based on sequence. Partitioning steps can be iterated indefinitely, with worst-case yields of 85% per step. These techniques facilitate DNA programmed chemical synthesis, and thus enable a materials biology that could revolutionize drug discovery. biology tools

Ilick2004 200401 We have used a resonating mechanical cantilever to detect immunospecific binding of viruses, captured from liquid. As a model virus, we used a nonpathogenic insect baculovirus to test the ability to specifically bind and detect small numbers of virus particles. Arrays of surface micromachined, antibody-coated polycrystalline silicon nanomechanical cantilever beams were used to detect binding from various concentrations of baculoviruses in a buffer solution. Because of their small mass, the 0.5 um x 6 um cantilevers have mass sensitivities on the order of 10-19 gHz, enabling the detection of an immobilized AcV1 antibody monolayer corresponding to a mass of about 3x10-15 g. With these devices, we can detect the mass of single-virus particles bound to the cantilever. Resonant frequency shift resulting from the adsorbed mass of the virus particles distinguished solutions of virus concentrations varying between 10^5 and 10^7 pfu/ ml. Control experiments using buffer solutions without baculovirus showed small amounts less than 50 attograms of nonspecific adsorption to the antibody layer. / cantilever sensors

Jahnchke2004 200401 In scanning probe microscopy, it is critical to maintain small probe sample separations for high resolution imaging. Quartz crystal tuning forks are typically used for detecting shear forces in near-field scanning optical microscopy and normal forces in other atomic force-related microscopies. In this article we compare several tuning fork based detection schemes to determine which solution gives the best signal to noise ratio. The high impedance and low signals produced by the tuning fork necessitate care in selection of an appropriate preamplifier. We find that a carefully guarded voltage preamplifier sensing a mechanically driven tuning fork performs the best, but an electrically driven fork with a current preamplifier offers simpler construction with only 25% lower signal to noise ratio on average. oscillator snr

Peres200401 200401 with Terno, This article discusses the intimate relationship between quantum mechanics, information theory, and relativity theory. Taken together these are the foundations of present-day theoretical physics, and their interrelationship is an essential part of the theory. The acquisition of information from a quantum system by an observer occurs at the interface of classical and quantum physics. The authors review the essential tools needed to describe this interface, i.e., Kraus matrices and positive-operator-valued measures. They then discuss how special relativity imposes severe restrictions on the transfer of information between distant systems and the implications of the fact that quantum entropy is not a Lorentz-covariant concept. This leads to a discussion of how it comes about that Lorentz transformations of reduced density matrices for entangled systems may not be completely positive maps. Quantum field theory is, of course, necessary for a consistent description of interactions. Its structure implies a fundamental tradeoff between detector reliability and localizability. Moreover, general relativity produces new and counterintuitive effects, particularly when black holes (or, more generally, event horizons) are involved. In this more general context the authors discuss how most of the current concepts in quantum information theory may require a reassessment. qm theory

The resistances of the states differ by up to 50% of the change due to complete magnetization reversal. Fluctuations are seen for a wide range of currents and magnetic fields, with rates that can exceed 2 GHz, and involve collective motion of a large volume s10^4 nm^3 of spins. Switching rate trends with field and current indicate that increasing temperature alone cannot explain the dynamics. The rates approach a stochastic regime wherein dynamics are governed by both precessional motion and thermal perturbations. rts spin

The prototype millimeter-scale NMR spectrometer shows signal and noise levels in agreement with the design principles.Wepresent 1H and 19F NMR in both solid and liquid samples, including timedomain Fourier transform NMR spectroscopy, multiple-pulse echoes, and heteronuclear J spectroscopy. By measuring a 1H-19F J coupling, this last experiment accomplishes chemically specific spectroscopy with force-detected NMR. In BOOMERANG, an assembly of permanent magnets provides a homogeneous field throughout the sample, while a harmonically suspended part of the assembly, a detector, is mechanically driven by spin-dependent forces. By placing the sample in a homogeneous field, signal dephasing by diffusion in a field gradient is made negligible, enabling application to liquids, in contrast to other force-detection methods. The design appears readily scalable to um-scale samples where it should have sensitivity advantages over inductive detection with microcoils and where it holds great promise for application of magnetic resonance in biology, chemistry, physics, and surface science.

The nanowires are grown in a chemical beam epitaxy system and exhibit high aspect ratios and high homogeneity in length and width. Investigations of wire growth rate as a function of diameter, density, and time were performed and the results indicate that 80% of the growth is due to In species diffusing from the (111)B substrate surface. Furthermore, we have established that the diffusion length on the 110 wire side surfaces exceeds 10 um.

Correlations between the charge on the SET island and the position of the resonator give rise to a distinctive noise spectrum which can be very different from that of the uncoupled SET. The current noise spectrum of the coupled system contains peaks at both the frequency of the resonator and double the resonator frequency, as well as a strong enhancement of the noise at low frequencies. The heights of the peaks are controlled by the strength of the coupling between the SET and the resonator, the damping of the resonator, and the temperature of the system.

It is rather generally believed that, at least in principle, by suitable active procedures of quantum error correction this problem can be solved if the level of noise is lower then a certain threshold. The aim of this note is to show that, unfortunately, the success of existing error correction procedures is due to the discrete in time modelling of quantum evolution.

Aliferis200412 200412 Phys Rev A, The ability to perform a universal set of quantum operations based solely on static resources and measurements presents us with a striking viewpoint for thinking about quantum computation and its powers. We consider the two major models for doing quantum computation by measurements that have hitherto appeared in the literature and show that they are conceptually closely related by demonstrating a systematic local mapping between them. This way we effectively unify the two models, showing that they make use of interchangeable primitives. With the tools developed for this mapping, we then construct more resourceeffective methods for performing computation within both models and propose schemes for the construction of arbitrary graph states employing two qubit measurements alone. qm measurement Caltech with Leung

Caron200412 200412 Using scanning probe techniques, surface properties such as shear stiffness and friction can be measured with a resolution in the nanometer range. The torsional deflection or buckling of atomic force microscope cantilevers has previously been used in order to measure the lateral forces acting on the tip. This letter shows that the flexural vibration modes of cantilevers oscillating in their width direction parallel to the sample surface can also be used for imaging. These lateral cantilever modes exhibit vertical deflection amplitudes if the cantilever is asymmetric in thickness direction, e.g., by a trapezoidal cross section. cantilever bending

Chiaverini200412 200412 with Wineland, Scalable quantum computation1 and communication require error control to protect quantum information against unavoidable noise. Quantum error correction protects information stored in two-level quantum systems (qubits) by rectifying errors with operations conditioned on the measurement outcomes. Error-correction protocols have been implemented in nuclear magnetic resonance experiments, but the inherent limitations of this technique prevent its application to quantum information processing. Here we experimentally demonstrate quantum error correction using three beryllium atomic-ion qubits confined to a linear, multi-zone trap. An encoded one-qubit state is protected against spin-flip errors by means of a three-qubit quantum error-correcting code. A primary ion qubit is prepared in an initial state, which is then encoded into an entangled state of three physical qubits (the primary and two ancilla qubits).Errors are induced simultaneously in all qubits at various rates.The encoded state is decoded back to the primary ion one-qubit state, making error information available on the ancilla ions, which are separated from the primary ion and measured. Finally,the primary qubit state is corrected on the basis of the ancillae measurement outcome. We verify error correction by comparingthe corrected final state to the uncorrected state and to the initial state. In principle, the approach enables a quantum state to be maintained by means of repeated error correction, an importantstep towards scalable fault-tolerant quantum computation using trapped ions. qm error

Matsen200412 200412 Traditional language learning theory explores an idealized interaction between a teacher and a learner. The teacher provides sentences from a language, while the learner has to infer the underlying grammar. Here, we study a new approach by considering a population of individuals that learn from each other. There is no designated teacher. We are inspired by the observation that children grow up to speak the language of their peers, not of their parents. Our goal is to characterize learning strategies that generate ÔÔlinguistic coherence,ÕÕ which means that most individuals use the same language. We model the resulting learning dynamics as a random walk of a population on a graph. Each vertex represents a candidate language. We find that a simple strategy using a certain aspiration level with the principle of winÐstay, loseÐshift does extremely well: stay with your current language, if at least three others use that language; otherwise, shift to an adjacent language on the graph. This strategy guarantees linguistic coherence on all nearly regular graphs, in the relevant limit where the number of candidate languages is much greater than the population size. Moreover, for many graphs, it is sufficient to have an aspiration level demanding only two other individuals to use the same language. language theory

The amplitude of the fundamental transverse mode behaves like a weakly damped quantum particle in a driven anharmonic potential. Upon using a Born-Markovian master equation, we calculate the fundamental mode amplitude for varying driving frequencies. In the nonlinear regime, we observe resonances which are absent in the corresponding classical model. They are shown to be associated with resonant multiphonon excitations. Furthermore, we identify resonant tunneling in a dynamically induced bistable effective potential. qm oscillators

Cho200501 200501 with McKenzie, We theoretically study thermal transport in an electronic interferometer comprising a parallel circuit of two quantum dots, each of which has a tunable single electronic state which are connected to two leads at different temperature. As a result of quantum interference, the heat current through one of the dots is in the opposite direction to the temperature gradient. An excess heat current flows through the other dot. Although locally, heat flows from cold to hot, globally the second law of thermodynamics is not violated because the entropy current associated with heat transfer through the whole device is still positive. The temperature gradient also induces a circulating electrical current, which makes the interferometer magnetically polarized. spintronics interferometer

Page200502 200502 In the Joint Center for Structural Genomics, one-dimensional (1D) 1H NMR spectroscopy is routinely used to characterize the folded state of protein targets and, thus, serves to guide subsequent crystallization efforts and to identify proteins for NMR structure determination. Here, we describe 1D 1H NMR screening of a group of 79 mouse homologue proteins, which correlates the NMR data with the outcome of subsequent crystallization experiments and crystallographic structure determination. Based on the 1D 1H NMR spectra, the proteins are classified into four groups, ÔÔAÕÕ to ÔÔD.ÕÕ A-type proteins are candidates for structure determination by NMR or crystallography; ÔÔBÕÕ-type are earmarked for crystallography; ÔÔCÕÕ indicates folded globular proteins with broadened line shapes; and ÔÔDÕÕ are nonglobular, ÔÔunfoldedÕÕ polypeptides. The results obtained from coarse- and fine-screen crystallization trials imply that only A- and B-type proteins should be used for extensive crystallization trials in the future, with C and D proteins subjected only to coarse-screen crystallization trials. Of the presently studied 79 soluble protein targets, 63% yielded A- or B-quality 1D 1H NMR spectra. Although similar yields of crystallization hits were obtained for all four groups, A to D, crystals from A- and B-type proteins diffracted on average to significantly higher resolution than crystals produced from C- or D-type proteins. Furthermore, the output of refined crystal structures from this test set of proteins was 4-fold higher for A- and B-type than for C- and D- type proteins. structure determination pipelines (11Ð13) to obtain extensive structural coverage of a bacterial (Thermotoga maritima) and a eukaryotic (Mus musculus) proteome.

Bargatin200503 200503 Sensitive detection of nanomechanical motion using piezoresistive signal downmixing, We have developed a method of measuring rf-range resonance properties of nanoelectromechanical systems sNEMSd with integrated piezoresistive strain detectors serving as signal downmixers. The technique takes advantage of the high strain sensitivity of semiconductor-based piezoresistors, while overcoming the problem of rf signal attenuation due to a high source impedance. Our technique also greatly reduces the effect of the cross-talk between the detector and actuator circuits. We achieve thermomechanical noise detection of cantilever resonance modes up to 71 MHz at room temperature, demonstrating that downmixed piezoresistive signal detection is a viable high-sensitivity method of displacement detection in high-frequency NEMS. dsp cantilevers Caltech University with Roukes

The periodic driving signal with a controlled modulation amplitude was provided by a 415 nm diode laser, wherein the laser spot was located at some distance away from the clamped end of the cantilever. The measured resonant response of the cantilever was obtained at distances in excess of 160 um with varying oscillator dimensions. The effectiveness of the driving mode is studied for different combinations of materials, namely SiÐSiO2 and Si3N4ÐSiO2. These observations were considered within the theoretical framework of the mechanism of heat transfer.
