Electrically-Driven and Exponentially-Enhanced Spin-Photon Interfaces for Quantum Networks

Abstract

We present an electrically-driven scheme for spin-photon quantum interfaces used in quantum networks. Through modulating the motion of a nano cantilever with voltages, optomechanical coupling and spin-mechanical coupling can be exponentially enhanced simultaneously. Numerical simulations show that by applying well-designed voltages high-fidelity quantum interface operations such as generation and absorption of a single-photon with a known wave packet are within the reach of current techniques.
