  • QUANTUM CIRCUIT BASED ON PROGRAMMABLE OPTICAL ULTRAFAST TEMPORAL INTERFEROMTERIC NETWORK ELEMENTS
    Publication number: 20240135221
    Abstract: A quantum computing system is set forth, comprising a photon source for generating short duration single photon pulses, at least one temporal interferometric network for time-bin encoding each short duration single photon pulse in a single spatial mode, wherein the temporal interferometric network includes at least one optical switch, at least one birefringent material and at least one polarization element, and a photon detector for detecting time-of-arrival of photons output from the temporal interferometric network to measure the state of the photons

  • Method of non-destructively testing a sputtering target
    Patent number: 5406850
    Abstract: A method of quality control for targets intended for use in the sputtering process. A test parameter is established by immersing the target in a tank of liquid, irradiating the target with ultrasonic energy in the Rayleigh frequency range, and integrating the portion of the ultrasonic energy which passes through the target and reflects off the back wall. This test parameter is closely related to the uniformity of a film which may be sputtered from the target onto a substrate.
