QuIC: Cavity QED Experiment

First paper from the QUIC-QED experiment published:

Cavity QED with magnetically coupled collective spin states
We report strong coupling between an ensemble of nitrogen-vacancy center electron spins in diamond and a superconducting microwave coplanar waveguide resonator. The characteristic scaling of the collective coupling strength with the square root of the number of emitters is observed directly.
