We report on the transmission of telecom photons entangled with a multimode solid-state
quantum memory over a deployed optical fiber in a metropolitan area. Photon pairs were …

Multi-photon quantum key distribution (QKD) protocols can use non-ideal photon emitters
and yet stay secure. As a result, they are advantageous over other single photon prepare …

The ability to store large amounts of photonic quantum states is regarded as substantial for
future optical quantum computation and communication technologies. However, research for …

To store quantum information, quantum memory plays a central intermediate ingredient in a
network. The minimal criterion for a reliable quantum memory is the maintenance of the …

We present experimental results on tuning biphoton frequency by introducing a detuned
coupling field in spontaneous four-wave mixing (SFWM), and examine its impact on the …

Quantum key distribution (QKD) will most likely be an integral part of any practical quantum
network setup in the future. However, not all QKD protocols can be used in today's networks …

Entanglement swapping (ES) between memory repeater links is critical for establishing
quantum networks via quantum repeaters. So far, ES with atomic-ensemble-based …
