Hybrid quantum systems that combine the complementary strengths of different quantum elements provide a powerful platform for exploring quantum physics and advancing emerging technologies. Building on our recent demonstration of strong spins-photon coupling and long coherence times using sodium atoms in neon crystals atop superconducting resonators, I will present our progress toward extending this cryogenic crystal platform to polar molecules. Here, molecules are implanted nanometers from the superconducting surface and occupy the resonator mode volume, enabling efficient dipolar interaction. As an initial step, we embed ammonia in neon crystals; its inversion transition, with a dipole moment of ~1.5 D, lies near 24 GHz in the gas phase. I will show multimode-resonator spectroscopy that resolves the crystal-shifted inversion transition and reveals contributions from higher rotational states. I will then outline our implementation of frequency-tunable superconducting resonators for observation of vacuum Rabi splitting – a clear signature of strong electric-dipole coupling. This work establishes polar molecules in cryocrystals as a versatile interface to superconducting circuits, opening a path toward programmable hybrid quantum processors.
