Coupling artificial atoms in diamond to mechanical resonators

Diamond color-centers are luminescent point-defects that can function as artificial atoms. They have recently attracted attention in quantum optics due to their remarkable optical and spin properties. The spin-levels of these atoms can be used as a solid-state memory for quantum states, while their fluorescence can be used to interface this memory with light.

Our research focuses on building efficient light-matter interfaces with these color-center qubits for applications in quantum information science and sensing. By fabricating nanoscale photonic and mechanical devices around these color centers, we can strongly couple their internal states to photons and phonons. In this talk, I will describe our recent experiments on color-centers in diamond nano-cantilevers, and discuss our approach towards strong spin-phonon coupling with this system.
