Room-temperature photonic quantum computing in integrated silicon photonics with germanium-silicon single-photon avalanche diodes

Neil Na, Chou-Yun Hsu, Erik Chen +1

Most, if not all, photonic quantum computing (PQC) relies upon superconducting nanowire single-photon detectors (SNSPDs) based on niobium (Nb) operated at a temperature < 4 K. This…
