A NANOSCALE INTERFACE BETWEEN ATOMS AND PHOTONS

The realization of strong atom-photon interactions is a central theme in quantum optics and an essential prerequisite for future quantum applications. We achieve such interactions using a system of neutral atoms and optical photons interfaced via a photonic crystal cavity. I will present our observations of strong cavity-mediated coupling between two atoms individually controlled and trapped in optical tweezers. I will also discuss our recent progress on generating entanglement between two atoms, a cornerstone for building quantum networks and studying quantum many-body physics based on atom arrays coupled to nanophotonic devices.
