报告题目：Hybrid quantum devices with NV centers, nanomechanics, and microwave cavities
报告摘要：Hybrid quantum architectures take the advantages and strengths of different components,involving degrees of freedom of completely different nature, which are promising for developing new quantum technologies and discovering rich physics.
I will present our recent work in the field of hybrid quantum systems with NV centers, nanomechanical resonators, and superconducting cavities.
I first analyze a hybrid device by integrating a microscale diamond beam with a single built-in nitrogen-vacancy (NV) center spin to a superconducting coplanar waveguide (CPW) cavity. Then I will discuss another hybrid quantum device with NV centers in diamond coupled to carbon nanotubes. Finally, I will discuss a proposal for a quantum delayed-choice experiment with a spin-mechanical setup.
