Towards a high cooperativity spin-mechanical system with NV centers and high-Q silicon nitride nanobeams

ORAL

Abstract

A hybrid spin-mechanical platform takes advantage of the properties of its constituents, such as the long-lived coherence of solid state spins and the high interfaceability of nanomechanical resonators. In particular, our platform consists of high-Q silicon nitride nanobeams coupled to NV centers inside nanopillar probes. We present measurements of the spin-mechanical coupling, as well as our current efforts to reach the high cooperativity regime via better positional control and even higher quality factors. We also discuss how our unique scanning probe geometry could enable programmable, long-range entanglement of distant spins via mechanical resonators.
