摘要： Nonlinear electromagnetic elements can efficiently implement quantum information processing tasks such as controlled phase shifts, non-demolition state detection, quantum subspace projections, non-demolition Bell state analysis, heralded state preparation, quantum non-demolition encoding, and fundamental quantum gate operations. Direct use of electromagnetic non-linearity can amplify small phase shifts and use feed forward systems in a near deterministic manner with high operating efficiency. Measurements using homodyne detectors can cause near deterministic projection of input states on a Hilbert subspace identified by the measurement results. Feed forward operation can then alter the projected state if desired to achieve a desired output state with near 100% efficiency.

摘要： A device capable of efficiently detecting a single-photon signal preserves a photon characteristic such as polarization or angular momentum. The device can include a beam splitter that splits an input photon state into modes that are distinguished by states of a characteristic of signal photons in the input photon state, a non-destructive measurement system capable of measuring a total number of photons in the modes without identifying a photon number for any individual one of the modes; and a beam combiner positioned to combine the modes after output from the non-destructive detection system.

摘要： A method and system for compensating for motion blur in optical navigation adds a correction offset to an image navigation value to adjust for varying velocities along a moving web. Reference and comparison images are acquired at different times from a moving web. An optical navigation value is computed representative of the movement of the web from the reference image to the comparison image. Blur distances for the two images can be calculated. A navigation error correction value is computed as one-half the difference between the reference blur distance and the comparison blur distance. A compensated navigation value is computed by adding the error correction value to the computed navigation value to compensate for varying web velocities.

摘要： Embodiments of the present invention include dense, but accessible and well-interconnected component arrangements within multi-component systems, such as high-end multi-processor computer systems, and methods for constructing such arrangements. In a described embodiment, integrated-circuit-containing processing components, referred to as a “flat components,” are arranged into local blocks of intercommunicating flat components. The local flat-component blocks are arranged into interconnected, primitive multi-local-block repeating units, and the primitive local-block repeating units are layered together in a three-dimensional, regularly repeating structure that can be assembled to approximately fill any specified three-dimensional volume. The arrangement provides for relatively short, direct pathways from the surface of the specified volume to any particular local block and flat component within the three-dimensional arrangement.

摘要： A method and apparatus are provided for efficiently obtaining navigational position of a sensor array based on a correlation between images captured by the sensor array at successive points in time. This is achieved by first acquiring a reference frame through said sensor array, successively acquiring a sample frame through said sensor array. Correlation data representing a relationship between the sample frame and the reference frame is then generated and a displacement of a reference feature contained in both the reference frame and the sample frame is determined based on the correlation data. The correlation surface of the correlation data is modeled as a general two-dimensional Taylor series expansion. The method and apparatus of the present invention can be advantageously employed in a scanning device to provide efficient scheme for obtaining navigational information based on a comparison of image frames captured by a sensor array of the scanning device at successive points in time.

摘要： Nonlinear elements can efficiently implement quantum information processing systems such as controlled phase shifters, non-absorbing detectors including parity detectors, quantum subspace projections, non-absorbing Bell state analyzers, non-absorbing encoders/entanglers, and fundamental quantum gates such as CNOT gates. The non-absorbing detectors permit improvements in the efficiency of a probabilistic quantum gate by permitting reuse of the same photonic resources during multiple passes through the probabilistic gate.
