Our group explores quantum optical phenomena of solid state systems, including spins in diamond, excitons in semiconductors, and mechanical excitations in microspheres and nanobeams. We develop new experimental techniques for the manipulation of spins, excitons, and mechanical excitations via optical interactions. The emphasis is on the understanding, control, and possible application of quantum coherence and entanglement in these systems.

We aim to control optical interactions at the level of single photons, single phonons, and single electron spins, enabling applications in quantum information processing. We also explore the possibility of cooling a macroscopic mechanical system to its motional ground state, which will open up opportunities for investigating quantum behaviors in an otherwise classical mechanical system.
