Secure quantum key distribution (QKD) over 76 km of optical fiber
Anton Zavriyev, Darius Subacius, Alexei S. Trifonov · 2005
We describe our recent experiments on one-way QKD in optical fibers. We used both, weak coherent pulses (WCP) as well as a heralded single photon source based on parametric down conversion of CW light.
