Abstract: A cable harness assembly includes a cable having a pair of wires and a connector assembly including an inner ferrule formed of a conductive material. Each of the wires has a conductor and a insulation disposed around the conductor. The pair of wires have a twisted region and an untwisted region. The inner ferrule has a cable passageway extending through the inner ferrule and a separator disposed within the cable passageway. The untwisted region is disposed in the inner ferrule and the separator is disposed between the wires in the untwisted region.

Abstract: A quantum computing D-state AC-Stark shift gate system comprises at least one gate manipulation source and one or more ions trapped in an ion trap. The at least one gate manipulation source is configured to generate a first gate manipulation signal and a second gate manipulation signal. The first and second gate manipulation signals couple an ion between a set of S-states and a set of D-states. The first and second gate manipulation signals apply a force to an ion of the one or more ions that is dependent on the internal state of the ion. The first and second gate manipulation signals are configured to couple internal states of the ions to their motional state without appreciably altering a population of the ions within the set of S-states.

Abstract: A quantum cryptography apparatus and system includes a photon emitter, a photon receiver, a first photodetector, a second photodetector, a first polarization optic, and a second polarization optic. The photon emitter is configured to emit a photon at a wavelength, wherein the photon emitter is coupled to the photon receiver by at least one quantum channel. The photon receiver includes the first polarization optic configured to output a polarization state of the emitted photon. The first photodetector is configured to detect the photon emitted from the output of the first polarization optic. The second photodetector is configured to detect a backflash from the first photodetector. The second polarization optic is between the first photodetector and the second photodetector. The quantum cryptography apparatus may be a quantum key distribution system for characterizing backflashes.

Abstract: Methods and apparatus for generating switch-initiated trespass commands. In an exemplary embodiment, a method includes recognizing that a first switch has a first path to a first target, which is coupled to a logical unit, and a second path to a second target, recognizing that a second switch has a first path to the first target and a second path to the second target, the second target being coupled to the logical unit, and determining whether the first switch should issue a trespass command.
