Abstract

Low photon extraction efficiency limits the optical spin readout fidelity in emerging quantum sensing technologies in diamond. Here, we propose and fabricate integrated diamond nanoprobes based on cavity-enhanced IR absorption of embedded Nitrogen Vacancy centers. The design allows for near-unity readout fidelity, enables high spatial resolution and massively parallel detection schemes.
