High-efficiency and fast photon-number resolving parallel superconducting nanowire single-photon detector
Lorenzo Stasi, Gaëtan Gras, Riad Berrazouane +3
Photon-number resolving (PNR) single-photon detectors are an enabling technology in many areas such as photonic quantum computing, non-classical light source characterisation and q…
Quantum entropy model of an integrated QRNG chip
Gaëtan Gras, Anthony Martin, Jeong Woon Choi +1
We present the physical model for the entropy source of a quantum random number generator chip based on the quantum fluctuations of the photon number emitted by light-emitting diod…
Countermeasure against quantum hacking using detection statistics
Gaëtan Gras, Davide Rusca, Hugo Zbinden +1
Detector blinding attacks have been proposed in the last few years, and they could potentially threaten the security of QKD systems. Even though no complete QKD system has been hac…
Direct measurement of the recovery time of superconducting nanowire single-photon detectors
Claire Autebert, Gaëtan Gras, Emna Amri +4
One of the key properties of single-photon detectors is their recovery time, i.e. the time required for the detector to recover its nominal efficiency. In the case of superconducti…
Optical control of single-photon negative-feedback avalanche diode detector
Gaëtan Gras, Nigar Sultana, Anqi Huang +4
We experimentally demonstrate optical control of negative-feedback avalanche diode (NFAD) detectors using bright light. We deterministically generate fake single-photon detections…
Secure quantum key distribution over 421 km of optical fiber
Alberto Boaron, Gianluca Boso, Davide Rusca +10
We present a quantum key distribution system with a 2.5 GHz repetition rate using a three-state time-bin protocol combined with a one-decoy approach. Taking advantage of supercondu…
