A quantum network node based on SnV centers in diamond
We report spin control of a tin vacancy center in diamond and observe a coherence time of up to 10 ms. We also control a nearby carbon nuclear spin with up to 1 s coherence. Finally, we incorporate SnV centers in a microcavity and achieve a cooperativity of 0.3, substantiating the potential of SnV centers in diamond for quantum network nodes.
