Photon-mediated interactions between quantum systems are essential for realizing networks and scalable information processing. We demonstrate such pairs of silicon-vacancy (SiV) color centers strongly coupled to a diamond nanophotonic cavity. When the optical transitions two tuned into resonance, coupling common cavity mode results in coherent interaction them, leading spectrally-resolved superradiant subradiant states. use electronic spin degrees freedom SiV control these optically-mediated interactions. Our experiments pave way implementation cavity-mediated gates qubits realization network nodes.
