Title Superconducting single-photon counting system for optical experiments requiring time-resolution in the picosecond range Type Journal Article
Year 2012 Publication Abbreviated Journal AIP REVIEW OF SCIENTIFIC INSTRUMENTS
Volume 83 Issue Pages
Keywords (up) SSPD, picosecond, time-resolution
Abstract We have developed a cryogenic measurement system for single-photon counting, which can be used

in optical experiments requiring high time resolution in the picosecond range. The system utilizes

niobium nitride superconducting nanowire single-photon detectors which are integrated in a timecorrelated

single-photon counting (TCSPC) setup. In this work, we describe details of the mechanical

design, the electrical setup, and the cryogenic optical components. The performance of the complete

system in TCSPC mode is tentatively benchmarked using 140 fs long laser pulses at a repetition

frequency of 75MHz. Due to the high temporal stability of these pulses, the measured time resolution

of 35 ps (FWHM) is limited by the timing jitter of the measurement system. The result was crosschecked

in a Coherent Anti-stokes Raman Scattering (CARS) setup, where scattered pulses from a

β-barium borate crystal have been detected with the same time resolution.

Title Superconducting optical single-photon detectors Type Conference Article
Year 2004 Publication CLEO/QELS Abbreviated Journal CLEO/QELS
Volume Issue Pages IThD1
Keywords (up) SSPD, QE, jitter, dark counts
Abstract We review the development of superconducting single-photon detectors. The devices are characterized by experimental quantum efficiency of ~8% for infrared photons, counting rate ~2 GHz, 18 ps jitter, and <0.01 per second dark counts.

Title High rate long-distance quantum key distribution over 250 km of ultra low loss fibres Type Journal Article
Year 2009 Publication New J. Phys. Abbreviated Journal
Volume 11 Issue 7 Pages 075003
Keywords (up) SSPD, quantum cryptography, QKD, COW
Abstract We present a fully automated quantum key distribution prototype running at 625 MHz clock rate. Taking advantage of ultra low loss fibres and low-noise superconducting detectors, we can distribute 6,000 secret bits per second over 100 km and 15 bits per second over 250km.

Title Investigating the detection regimes of a superconducting single-photon detector Type Journal Article
Year 2013 Publication J. Opt. Technol. Abbreviated Journal J. Opt. Technol.
Volume 80 Issue 7 Pages 435
Keywords (up) SSPD, quantum efficiency
Abstract The detection regimes of a superconducting single-photon detector have been investigated. A technique is proposed for determining the regions in which “pure regimes” predominate. Based on experimental data, the dependences of the internal quantum efficiency on the bias current are determined in the one-, two-, and three-photon detection regimes.
