A three-node quantum network

Future quantum networks will provide the means to develop truly secure communication channels and will have applications in many other quantum-based technologies. Pompili et al. present a three-node remote quantum network based on solid-state spin qubits (nitrogen-vacancy centers in diamond) coupled by photons. The implementation of two quantum protocols on the network. entanglement distribution and entanglement swapping, illustrates a key platform for exploring, testing, and developing multinode quantum networks and quantum protocols.
