A Quantum Key Distribution Channel Based on Optical Fibre
Paul D. Townsend, I. Thompson · Journal of Modern Optics · 1994
We describe a prototype quantum key distribution system based on standard optical communication fibre and components. The system has been used to transmit pseudo-random bit sequences encoded in the phase of quasi-single-photon pulses over a distance of 10 km. Bit sequences containing about 150 bits were transmitted in bursts 2 ms long with acceptable error rates of about 5%.
