  • Publication number: 20100258746
    Abstract: Deterministic generation of nonclassical photons by producing a dilute gas of exciton-polaritons in a solid-state microcavity that includes a periodic array of potential well traps. A photon-exciton frequency detuning is modulated in the microcavity to produce a polaritonic quantum phase transition from a superfluid state to a Mott-insulator state. The nonclassical photons are then generated simultaneously by radiative decay of exciton-polaritons in the microcavity. The nonclassical photons may be indistinguishable single photons, in which case the dilute gas of exciton-polaritons is produced such that on to average there is one polariton per potential well trap. Alternatively, the generated nonclassical photons may be polarization-entangled photon pairs, in which case the dilute gas of exciton-polaritons is produced such that on average there are two polaritons per potential well trap.

  • Patent number: 7784492
    Abstract: In a direction control valve, a bottom face of an insertion hole of a first movable member is at a predetermined distance from a second movable member with respect to a first axial direction when communication between a first communication switching port and a communication object port is made and communication between a second communication switching port and the communication object port is broken. The bottom face contacts and pushes the second movable member in a second axial direction opposite to the first axial direction after the first movable member moves in the second axial direction by the predetermined distance while the first and second movable members move in the second axial direction to switch a port communicating with the communication object port from the first communication switching port to the second communication switching port.

  • Patent number: 7775336
    Abstract: Lubricating oil supply holes are drilled into a first member that is fitted to a plurality of first annular plates by a spline. Of splines to which each lubricating oil supply hole corresponds, lubricating oil grooves provided in the plurality of first annular plates do not overlap the splines on at least one of the front and rear surfaces of the first annular plates, and therefore lubricating oil flowing out of the lubricating oil supply holes is dispersed in a circumferential direction and flows from the inner periphery to the outer periphery of the first annular plates, rather than gathering in each lubricating oil groove and flowing in an outer peripheral direction. As a result, a force generated by an axial lubricating oil flow, which acts in a direction for causing the second annular plates to contact friction materials on the first annular plates, is suppressed, leading to a reduction in drag torque.

  • Publication number: 20100034390
    Abstract: Differential phase shift (DPS) quantum key distribution (QKD) is provided, where the average number of photons per transmitted pulse is predetermined such that the secure key generation rate is maximal or nearly maximal, given other system parameters. These parameters include detector quantum efficiency, channel transmittance and pulse spacing (or clock rate). Additional system parameters that can optionally be included in the optimization include baseline error rate, sifted key error rate, detector dead time, detector dark count rate, and error correction algorithm performance factor. The security analysis leading to these results is based on consideration of a hybrid beam splitter and intercept-resend attack.
