    摘要： A security system uses a source capable of producing an entangled state of a sensing mode and a reference mode. The sensing mode has a path that enters an area around an object being secured. A state measurement system in the security system can measure a combination of the sensing mode after traversal of the sensing path and the reference mode after traversal of a reference path.

    摘要： Various embodiments of the present invention are directed to methods for determining a phase shift acquired by an entangled N-qubit system represented by a NOON state. In one embodiment, a probe electromagnetic field is coupled with each qubit system. The phase shift acquired by the qubit systems is transferred to the probe electromagnetic field by transforming each qubit-system state into a linear superposition of qubit basis states. An intensity measurement is performed on the probe electromagnetic field in order to obtain a corresponding measurement result. A counter associated with a measurement-result interval is incremented, based on the measurement result falling within the measurement-result interval. A frequency distribution is produced by normalizing the counter associated with each measurement-result interval for a number of trials. The phase shift is determined by fitting a probability distribution associated with the probe electromagnetic field to the frequency distribution as a function of the phase shift.

    摘要： Various embodiments of the present invention are directed to photonic-interconnection-based compute clusters that provide high-speed, high-bandwidth interconnections between compute cluster nodes. In one embodiment of the present invention, the compute cluster includes a photonic interconnection having one or more optical transmission paths for transmitting independent frequency channels within an optical signal to each node in a set of nodes. The compute cluster includes one or more photonic-interconnection-based writers, each writer associated with a particular node, and each writer encoding information generated by the node into one of the independent frequency channels. A switch fabric directs the information encoded in the independent frequency channels to one or more nodes in the compute cluster. The compute cluster also includes one or more photonic-interconnection-based readers, each reader associated with a particular node, and each reader extracting the information encoded in the independent frequency channels directed to the node for processing.

    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 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. The instant velocities of the web are determined for the acquisition times for the reference and comparison images, wherein the reference image velocity and the comparison image velocity may not be the same. An optical navigation value is computed representative of the movement of the web from the reference image to the comparison image. Based on the determined velocities and the image acquisition time, the 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 invention provide a method and an apparatus for forming a photodiode. One embodiment provides a thin dielectric layer sandwiched between two metallic plates (electrodes), one or both of which are periodically patterned in one or two dimensions. The effect of the pattern is to couple incident light within some range of wavelength and/or incidence angles to surface excitations of the metal surface called surface plasmons, enhancing the electric field near the surface and resulting in dramatically increased photo-absorption and carrier generation in the dielectric layer.
