Quantum networks based on diamond NV centers

Quantum networks are poised to enable large-scale secure communication, distributed quantum computing and simulation by means of shared entangled states over the nodes of the network. The Nitrogen-Vacancy (NV) centre in diamond is a promising candidate to act as node of such a quantum network, with long-lived multiple qubits and an optical interface for entanglement. We present updates on our effort towards the realisation of such a network.
