Abstract: Hybrid quantum systems offer a promising platform to study quantum phenomena that benefit from the individual strengths of their components. A new emerging hybrid quantum platform composed of spin-doped solid noble gas crystals and superconducting resonators. The noble gas crystals offer a soft, inert, predominantly spin-0 host matrix for the atomic impurities, while the alkali atoms have addressable hyperfine transitions in the GHz regime. In my talk, I will present this novel platform and demonstrate how to reach the strong coupling regime between the impurity ensemble and the superconducting resonator at mK temperatures for efficient coherent information exchange. I will also show coherence time measurements proving its suitability for quantum applications. At the end of my talk, I will discuss how this unique architecture can be used for exploring fundamental quantum effects and new technologies.
