Abstract

We report our progress towards the demonstration of telecom-heralded matter-matter entanglement between solid-state, on-demand and remote quantum memories based on rare-earth—doped crystals.

Heralded Quantum Entanglement between two Rare-Earth-Ion Doped Crystals

Two rare-earth-ion doped crystals were entangled by converting a single photon into a delocalized excitation. The excitation was subsequently converted back into a photon and the entanglement revealed by an estimation of the concurrence.
