Secure Quantum Key Distribution (QKD) over 76 km of optical fiber

Not Accessible

Your library or personal account may give you access

Abstract

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.
