Paper Abstract

We are developing solid-state quantum repeaters for long-distance, secure quantum communication networks. These repeaters will combine long-range quantum entanglement, produced by optical measurements, with local few-qubit quantum processing and storage nodes. So far we have demonstrated all the key elements of the local quantum processors using nitrogen-vacancy (NV) color centers in diamond. These include multi-qubit entanglement, long storage times, and robustness against multiple re-initialization steps. Significantly, all these local operations were demonstrated at room temperature. Finally, we estimate that single shot readout should be achievable with optical plasmon wire coupling which would open the door to room-temperature few-qubit quantum computers.
