Influence of laser chirp and interferometer delay and imbalance on the performance of a time-bin BB84 quantum key distribution system
Abstract
We investigate the effect of interferometer delay and imbalance on the performance of a BB84 time-bin quantum key distribution system. We simulate the impact of interference visibility on system performance and measure the visibility of a pair of interferometers as a function of their relative time delay and intensity imbalance. In addition, our analysis highlights the effect of laser chirp on system performance.
