Circuit Quantum ElectroDynamics combines superconducting microwave resonators on a chip with natural or artificial quantum objects. Along this line, spins can strongly interact with cavity electromagnetic fields, giving rise to hybridized spin-photon states with coherent dynamics. We study the coupling and the integration of molecular spin centers into planar microwave resonators in order to develop hybrid quantum devices.
