Protocol choice and parameter optimization in decoy-state measurement-device-independent quantum key distribution
Feihu Xu, He Xu, Hoi-Kwong Lo
Measurement-device-independent quantum key distribution (MDI-QKD) has been demonstrated in both laboratories and field-tests using attenuated lasers combined with the decoy-state t…
Investigations of afterpulsing and detection efficiency recovery in superconducting nanowire single-photon detectors
Viacheslav Burenkov, He Xu, Bing Qi +2
We report on the observation of a non-uniform dark count rate in Superconducting Nanowire Single Photon Detectors (SNSPDs), specifically focusing on an afterpulsing effect present…
Postprocessing for quantum random number generators: entropy evaluation and randomness extraction
Xiongfeng Ma, Feihu Xu, He Xu +3
Quantum random-number generators (QRNGs) can offer a means to generate information-theoretically provable random numbers, in principle. In practice, unfortunately, the quantum rand…
Ultrafast quantum random number generation based on quantum phase fluctuations
Feihu Xu, Bing Qi, Xiongfeng Ma +3
A quantum random number generator (QRNG) can generate true randomness by exploiting the fundamental indeterminism of quantum mechanics. Most approaches to QRNG employ single-photon…
