Abstract

We report on a quantum key distribution field trial in the Copenhagen metropolitan area using true single photons from a quantum-dot-based near-deterministic source. A stable secret key generation rate of 2 kbit/s with 9.6-dB channel loss is achieved with a polarization-based BB84 scheme.
