Abstract
We report the realization of a quantum circuit in which an ensemble of electronic spins is coupled to a frequency tunable superconducting resonator. The spins are nitrogen-vacancy centers in a diamond crystal. The achievement of strong coupling is manifested by the appearance of a vacuum Rabi splitting in the transmission spectrum of the resonator when its frequency is tuned through the nitrogen-vacancy center electron spin resonance.

Ensembles of dilute spin impurities in condensed matter systems can be accessed using microelectronic circuits and therefore may offer a way for long-term storage and enhanced processing of quantum information.
