Abstract
Time bin entangled photon pairs are robust against transmission fluctuations and suitable for long-distance quantum entanglement distribution. Here we report the first monolithically integrated silicon time-bin encoding entanglement system, which integrates the photon sources, wavelength demultiplexers, and Franson interferometers on a single chip. We measured quantum interference visibility of 98.98% ± 0.55%, which is among the highest yet reported for monolithic integrated time-bin entanglement systems.
