  Title (up) Single-photon superconducting detectors for practical high-speed quantum cryptography Type Miscellaneous
  Year 2001 Publication OFCC/ICQI Abbreviated Journal OFCC/ICQI  
  Volume Issue Pages Pa3  
  Keywords NbN SSPD, SNSPD, QKD, quantum cryptography  
  Abstract We have developed an ultrafast superconducting single-photon detector with negligible dark counting rate. The detector is based on an ultrathin, submicron-wide NbN meander-type stripe and can detect individual photons in the visible to near-infrared wavelength range at a rate of at least 10 Gb/s. The above counting rate allows us to implement the NbN device to unconditionally secret quantum key distRochester, New Yorkribution in a practical, high-speed system using real-time Vernam enciphering.

  Title (up) Terahertz-frequency waveguide NbN hot-electron bolometer mixer Type Journal Article
  Year 2001 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.  
  Volume 11 Issue 1 Pages 952-954  
  Keywords NbN HEB mixers  
  Abstract We have developed a low-noise waveguide heterodyne receiver for operation near 1 THz using phonon-cooled NbN hot-electron bolometers. The mixer elements are submicron-sized microbridges of 4 nm-thick NbN film fabricated on a quartz substrate. Operating at a bath temperature of 4.2 K, the double-sideband receiver noise temperature is 760 K at 1.02 THz and 1100 K at 1.26 THz. The local oscillator is provided by solid-state sources, and power measured at the source is less than 1 /spl mu/W. The intermediate frequency bandwidth exceeds 2 GHz. The receiver was used to make the first ground-based heterodyne detection of a celestial spectroscopic line above 1 THz.

  Title (up) The liquid helium cryogenic system for the superconducting cavity in SRRC Type Conference Article
  Year 2001 Publication Proc. Particle Accelerator Conference Abbreviated Journal  
  Volume 2 Issue Pages 1604-1606  
  Keywords  
  Abstract A 500 MHz superconducting cavity will replace the current copper cavity and begin to operate in the beginning of the year 2003. A liquid helium cryogenic system provides the cavity at 4.5 K a cooling capacity of 255 W without LN2 pre-cooling and a liquefaction rate of 110 liter/hour with LN2 pre-cooling. A safety factor of 1.5 is used to estimate the heat load from the superconducting cavity and the heat loss from the transfer lines. With the LN2 pre-cooling, this cooling system provides a cooling capacity of up to 450 W to cool down the additional superconducting Landau cavity. The capacity of the system can be tuned using a frequency driver installed at the compressor station. The pressure fluctuations of the dewar and of the suction line are kept to the same stability requirement that of the cavity cryostat to minimize the influence in cavity operation. A shutdown period for maintenance of more than 8000 hours for the cryogenic system is expected without interfering with the continuous operation of the superconducting cavity.
