Abstract:
Single-photon avalanche detectors (SPADs), which operate without cryogenic cooling, are a core component for practical QKD systems. We demonstrate 13-hour continuous key generation with our timebin-phase BB84 QKD system using our InGaAs/InP SPAD, yielding 1.88 ± 0.10% QBER and 85 ± 8 bit/s SKR over 41.6 km fiber.
