Temporal multimode storage of entangled photons

Our paper demonstrating the multimode storage of two entangled photons in the solid-state quantum memory recently has been published in Physical Review Letters. Our results conclusively demonstrate the capability of the rare-earth ion doped crystals for future multiplexed quantum communication over the long distances.

This work was a collaboration between several groups, Nicolas Brunner and Marcus Huber here in Geneva on the theory side, and experimentally, Sae Woo Nam's group in NIST and Francesco Marsilli's group at JPL, whose superconducting single photon detectors we used for the experiment.
