Hybrid Quantum Systems with Rare-Earth Ion Spin Ensemble — •Pavel Bushev — Physikalisches Institut, Karlsruher Institut für Technologie, 76131 Karlsruhe, Germany

Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers a promising route towards large scale distributed quantum computing. Ideal candidates for such coherent interface are optically active spin ensembles coupled to a superconducting resonators. Laser crystals doped with rare-earth ions present an excellent material with active spins, transitions in optical frequency range and hyperfine structure. The magnetic anisotropy of these materials makes their application in hybrid quantum systems quite challenging.

I will present our study of Er:YSO crystal coupled to superconducting resonator. The comparions of erbium to other rare-earth ions will also be given.
