Towards a multi-node network with NV centres in diamond

ORAL

Abstract

Quantum networks are expected to deliver definitive security for communication, blind quantum computation, improved clock synchronization and more exotic applications such as connecting far apart telescopes. A node of such a network must be capable of running small quantum computations, storing quantum information in memory qubits and generate entanglement with neighbouring nodes.

The nitrogen-vacancy (NV) in diamond is a strong candidate to act as node, as it combines all the mentioned requirements in a solid-state system. Deterministic generation of entanglement between two distant NV centres has been recently shown by our group.
We present our recent progress on the ongoing effort to generate genuine multipartite entanglement between three distant NV centres, as we overcome the obstacles to move beyond two node networks.
