Performance and security of 5 GHz repetition rate polarization-based Quantum Key Distribution
arXiv:2007.15447 · doi:10.1063/5.0021468
Abstract
We present and characterize a source for a 5 GHz clocked polarization-based simplified BB84 protocol. Secret keys are distributed over 151.5 km of standard telecom fiber at a rate of 54.5 kbps. Potentially, an increased clock frequency of the experiment introduces correlations between succeeding pulses. We discuss the impact of these correlations and propose measurements to estimate the relevant parameters.
