Polarization insensitive frequency conversion for an atom-photon entanglement distribution via a telecom network

Quantum repeater-based communication requires the ability to interface good quantum memories to telecom photons. Here, the authors report polarization-insensitive frequency conversion to telecom wavelength of a photon entangled with a Rb ensemble, preserving the entanglement in the process.
