Characteristics of superconducting single photon detector in DPS-QKD system under bright illumination blinding attack
Mikio Fujiwara, Toshimori Honjo, Kaoru Shimizu +2
We derive the time-dependent photo-detection probability equation of a superconducting single photon detector (SSPD) to study the responsive property for a pulse train at high repe…
Countermeasure against tailored bright illumination attack for DPS-QKD
Toshimori Honjo, Mikio Fujiwara, Kaoru Shimizu +6
We propose a countermeasure against the so-call tailored bright illumination attacl dor Differential-Phase-Shift QKD (DPS-QKD). By Monitoring a rate of coincidence detection at a p…
Superconducting nanowire single-photon detector with ultralow dark count rate using cold optical filters
H. Shibata, K. Shimizu, H. Takesue +1
We report the fabrication of a superconducting nanowire single-photon detector (SSPD or SNSPD) with an ultralow dark count rate. By introducing optical band-pass filters at the inp…
Slow light enhanced correlated photon pair generation in photonic-crystal coupled-resonator optical waveguides
Nobuyuki Matsuda, Hiroki Takesue, Kaoru Shimizu +3
We demonstrate the generation of quantum-correlated photon pairs from a Si photonic-crystal coupled-resonator optical waveguide. A slow-light supermode realized by the collective r…
