Single-photon detectors play a prominent role in quantum photonics. In this field, superconducting nanowire single-photon detectors (SNSPDs) excel in terms of performance, but their application is often limited by the necessity of cryogenic temperatures. Single-photon avalanche diodes (SPADs) represent an alternative in all these situations. Here, we focus on the progress made on silicon SPADs, whose performance in the visible range provide a valid option for several quantum applications, and, after that, we review the novel solutions that are blossoming for the telecom optical bands. In the end, we conclude with our vision of SPADs in quantum photonics applications.

Abstract
Single-photon detectors play a prominent role in quantum photonics. In this field, superconducting nanowire single-photon detectors (SNSPDs) excel in terms of performance, but their application is often limited by the necessity of cryogenic temperatures. Single-photon avalanche diodes (SPADs) represent an alternative in all these situations. Here, we focus on the progress made on silicon SPADs, whose performance in the visible range provide a valid option for several quantum applications, and, after that, we review the novel solutions that are blossoming for the telecom optical bands. In the end, we conclude with our vision of SPADs in quantum photonics applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
