Nonideal optical cavity structure of superconducting nanowire single photon detector
Hao Li, Weijun Zhang, Lixing You +8
Optical cavity structure has been proven to be a crucial factor for obtaining high detection efficiency in superconducting nanowire single photon detector (SNSPD). Practically, com…
Field Test of Measurement-Device-Independent Quantum Key Distribution
Yan-Lin Tang, Hua-Lei Yin, Si-Jing Chen +16
A main type of obstacles of practical applications of quantum key distribution (QKD) network is various attacks on detection. Measurement-device-independent QKD (MDIQKD) protocol i…
Measurement-device-independent quantum key distribution over 200 km
Yan-Lin Tang, Hua-Lei Yin, Si-Jing Chen +16
Measurement-device-independent quantum key distribution (MDIQKD) protocol is immune to all attacks on detection and guarantees the information-theoretical security even with imperf…
Superconducting nanowire single photon detector with on-chip bandpass filter
Xiaoyan Yang, Hao Li, Weijun Zhang +7
Dark count rate is one of the key parameters limiting the performance of the superconducting nanowire single photon detector (SNSPD). We have designed a multi-layer film bandpass f…
Characterization of superconducting nanowire single-photon detector with artificial constrictions
Ling Zhang, Lixing You, Dengkuan Liu +8
Statistical studies on the performance of different superconducting nanowire single-photon detectors (SNSPDs) on one chip suggested that random constrictions existed in the nanowir…
