Anisotropic Rare-Earth Spin Ensemble Strongly Coupled to a Superconducting Resonator
Anisotropic Rare-Earth Spin Ensemble Strongly Coupled to a Superconducting Resonator
Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers a promising route towards large scale distributed quantum computing. Ideal candidates for coherent qubit interconversion are optically active spins, magnetically coupled to a superconducting resonator. We report on an on-chip cavity QED experiment with magnetically anisotropic Er(3+)∶Y2SiO5 crystals and …
