Entanglement Distribution in Installed Fiber with Coexisting Classical Light for Quantum Network Applications
Jordan M. Thomas, Gregory S. Kanter, Ely M. Eastman, Kim Fook Lee, Prem Kumar · 2022
We show polarization entangled photons coexisting with milliwatt power classical light over 45.6 km of installed optical fiber. The entanglement source has a built-in alignment signal for quantum transmitter-receiver polarization basis alignment.
