Лекция 15: “Non-Markovian quantum dynamics in the strong-coupling limit of cavity QED”.

Among different hybrid quantum systems, the ones based on spin ensembles coupled to superconducting microwave cavities have recently attracted much attention. I will speak about the dynamics of an ensemble of negatively charged NV centers in diamond with a strong magnetic coupling to a superconducting single-mode waveguide resonator. Based on our theory we experimentally observe for the first time, how the decoherence induced by the inhomogeneous distribution of these NV centers can be suppressed in the strong-coupling regime — a phenomenon known as ”cavity protection”. More recently we could identify an even more powerful way to overcome the detrimental influence of inhomogeneous spin broadening that builds on the burning of two narrow spectral holes in the spin spectral density at judiciously chosen frequencies. Furthermore, we demonstrate that engineering the spin spectral density to acquire a comb-like structure leads to coherent revival dynamics with exciting potential for the processing of quantum information.
