Towards a Quantum Spin Transducer with Mechanical Resonators

Hybrid quantum systems that couple spins to mechanical degrees of freedom allow for a variety of applications in quantum metrology and quantum information processing. For example, one can use such a system to deterministically entangle spins over long distances through their coherent coupling with the dynamics of the resonator. Working towards this goal, we have constructed a system consisting of magnetically functionalized, doubly-clamped silicon nitride beam resonators positioned close to diamond nanopillars. We report on experimental progress towards achieving coherent coupling between the electronic spin states of individual NV centers and the resonator motion.
