在混合量子体系结构中连接光子和固态量子比特为大规模分布式量子计算提供了一条很有前途的途径。相干量子比特相互转换的理想候选者是光学活动自旋，它与超导谐振器磁耦合。我们报道了利用磁各向异性Er3+：Y2SiO5晶体进行的在片腔QED实验，并证明了稀土自旋与集总元素谐振器的集体强耦合。此外，在不需要腔体的情况下，通过直接微波吸收测量了Er自旋的电子自旋共振和驰豫动力学。DOI：10.1103/PhysRevLett.110.157001
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 inter-conversion are optically active spins, magnetically coupled to a superconducting resonator. We report on an on-chip cavity QED experiment with magnetically anisotropic Er3+:Y2SiO5 crystals and demonstrate collective strong coupling of rare-earth spins to a lumped element resonator. Moreover, the electron spin resonance and relaxation dynamics of the erbium spins are detected via direct microwave absorption, without the aid of a cavity. DOI: 10.1103/PhysRevLett.110.157001
