Quantum technology applications of rare earth crystals would benefit from accurate ab-initio models of how quantum properties arise from fundamental atom-atom interactions in crystals. In this project, we will adapt recent advances in molecular quantum chemistry models to rare earth crystals and apply them to quantum technology problems.

Quantum memories store light in atomic ensembles for applications in quantum computing and networking. This project explores how atoms and light interact in prototype quantum memories that use rare earth atoms in crystals for storage, aiming to improve memory efficiency,  storage capacity, and performance in real-world devices.

Superconducting and spin qubits are leading quantum computing technologies, but we currently have no way to connect them to optical quantum networks that will make up a future quantum internet. This project will develop an interconnect capable of efficiently converting microwave quantum information from these qubits to optical frequencies.
