• Abstract: Space-division multiplexing using multimode optical fibers has been applied to quantum-level signals with time-bin and phase encoding, achieving Mqubits per second over 8 km of few-mode fiber. The dead time of single-photon detectors, typically considered a bottleneck in quantum transmission, is effectively utilized here to eliminate modal cross-talk between quantum channels.

  Development of prototype metropolitan-scale quantum networks involves transmitting quantum information via deployed optical fibers. One approach addressing these challenges is to co-propagate classical probe signals in the same fiber as the quantum signal. Here, we demonstrate the distribution of polarization entangled quantum signals co-propagating with the White Rabbit Precision Time Protocol (WR-PTP) classical signals in the same single-core fiber strand at metropolitan-scale distances.
