Scaling up current quantum hardware to large numbers of their qubit building blocks is the one of the most pressing challenges in modern quantum technologies. To achieve this, one could separate qubits physically and mediate interaction between them by flying qubits. However, therefore one requires high interaction strength between the stationary and flying qubits. Here, we summarize our efforts to combine silicon nitride photonics and negatively charged silicon vacancy centers hosted in nanodiamonds to achieve this and build up a scalable interface between light and matter on the basis of this hybrid approach.
