Summary

A five-node relay swapped entanglement across four 10-kilometer links carrying conventional data.

The experiment multiplexed time-bin entangled photons beside C-band classical signals and completed entanglement swapping across a five-node, 40-kilometer relay while 10-gigabit-per-second traffic crossed every fiber. Measurements mapped the fidelity penalty from Raman noise. The authors describe it as the first entanglement-swapping demonstration on fibers simultaneously carrying conventional communications.
