Two Approaches to PNR and Ultrafast Detection with SNSPDs
Photon-number-resolving (PNR) and high speed detection of single photons are important for many applications in quantum information science. These include linear optical quantum computing, Gaussian boson sampling, improved heralded single-photon sources, quantum key distribution, and quantum network protocols based on quantum repeaters.
In this short video Félix Bussières, VP Research and Technology at ID Quantique (IDQ), discusses two approaches to photon-number resolution and ultrafast detection using Super-Conducting Nanowire Single-Photon Detectors (SNSPDs). The first approach (parallel design) is based on several interleaved pixels connected in parallel with a single readout line. This approach allows for PNR and ultrafast detection > 100 Mcps. The second approach (multi-pixel design) involves 4-16 independent pixels operated and read out independently. This enables even faster detection rates > 1 Gcps and PNR that is robust to long pulse durations.
