Quantum networks combine a high level of security and the ability to scale up the qubit number which is crucial for quantum information processing. These networks contain nodes that store information. Quantum communication can be enabled by linking these nodes via entanglement. Silicon vacancy color centers in diamonds are promising components for optically connected quantum processors. The point defects establish an efficient optical interface and display a protective inversion symmetry. Therefore, the incorporation of nanophotonic structures, as well as coherent resonators, is possible. This can be used to generate entanglement between spin and photonic qubits. Long coherence times are a benefit, however, this includes the challenge of working in a cryogenic environment. Here, we present a platform to generate efficient and secure quantum communication by connecting multiple quantum processors.
