Quantum network and repeaters

qubit-light interface

A challenge on the road towards a future quantum repeater is the transport of information between different nodes. Here, photon turn out to be an excellent long distance carrier of qubits. We aim with this experiment to develop an interface for mapping the quantum state of a photon to a single SiV in diamond. We employ a micro-optical fiber resonator: Because of the tiny mode volume of this resonator, the distance between the SiV in the diamond membrane and the mirror is below 10µm.
