Strong magnetic coupling of an inhomogeneous NV ensemble to a cavity
K. Sandner, H. Ritsch, R. Amsüss +5
We study experimentally and theoretically a dense ensemble of negatively charged nitrogen-vacancy centers in diamond coupled to a high superconducting coplanar waveguide cavity…

Cavity QED with magnetically coupled collective spin states
Robert Amsüss, Christian Koller, Tobias Nöbauer +9
We report strong coupling between an ensemble of nitrogen-vacancy center electron spins in diamond and a superconducting microwave coplanar waveguide resonator. The characteristic…
