A Spin-Mechanical System combining NV centers and high-Q Nanostrings in a Scanning Probe Setup

ORAL

Abstract

Hybrid quantum systems that couple spins to mechanical degrees of freedom allow for a variety of applications in quantum information processing, such as generating long-distance entanglement between solid-state spins via a mechanical resonator. Working towards this goal, we present a new platform consisting of magnetically functionalized, doubly-clamped silicon nitride beam resonators positioned close to diamond nanopillars. We report on measurements of coherent coupling between the electronic spin states of individual NV centers and the resonator motion, and show how this setup can be extended to generate programmable entanglement between many spins.
