Abstract: Silicon Vacancy color centers in diamond, coupled to nanophotonic crystal cavities, offer a promising platform for quantum network applications. Our system utilizes long qubit coherence times, high optical cooperativities, and on-chip scalability, forging a path toward the practical implementation of quantum networking protocols. In this talk, I will present our latest advancements in demonstrating distributed blind gates across a two-node network developed at Harvard. In our system, the two separate servers possess the matter qubits used for processing while the client performs photon measurements inaccessible to the servers. These measurements steer the matter qubits at the servers' locations via distributed entanglement. We demonstrate single and two-qubit universal blind gates within our hybrid matter-photon platform and show the first implementation of a blind gate distributed between matter qubits in different labs.
