Operation of parallel SNSPDs at high detection rates
Matthieu Perrenoud, Misael Caloz, Emna Amri +4
Recent progress in the development of superconducting nanowire single-photon detectors (SNSPD) has delivered ex-cellent performance, and their increased adoption has had a great im…
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…
High-Rate Photon Pairs and Sequential Time-Bin Entanglement with SiN Ring Microresonators
Farid Samara, Anthony Martin, Claire Autebert +4
Integrated photonics is increasing in importance for compact, robust, and scalable enabling quantum technologies. This is particularly interesting for developing quantum communicat…
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…
