In this grant we propose impurities in spin-0 quantum solids coupled to superconducting resonators as a novel hybrid system platform. The host crystal built from nuclear spin-0 constituents such as para-hydrogen or noble gases like Ne, or Ar provide a noise-free electromagnetic environment. The ‘softness’ of these host quantum solids should advantageously reduce stress-induced inhomogeneous broadening. With these unique environmental features, the favorable atomic properties of the impurities ought to be maintained. This new solid-state based system will be beneficial for a broad range of physics encompassing quantum information, quantum technologies and quantum metrology applications.

This experiment will benefit from the maturity of matrix isolation and superconducting hybrid quantum systems. However, combining these two fields results in a relatively unexplored and unique novel system capable of investigating a wide range of new physics. Uncommon to most platforms, a large variety of impurity species can be selected based on their desired properties. Beyond the characterization of the impurities, properties of the quantum solids can be explored as well.
