Low-loss, all-fiber system for strong and efficient coupling between distant atoms

A team of scientists from Waseda University, the Japan Science and Technology Agency, and the University of Auckland have developed an integrated, all-fiber coupled-cavities quantum electrodynamics (QED) system in which a meter-long portion of conventional optical fiber seamlessly and coherently connects two nanofiber cavity-QED systems.
