A cavity QED system for atom-photon interfacing and multi-atom investigations — •Kyle Arnold, Markus Baden, and Murray Barrett — Centre for Quantum Technologies, National University of Singapore, Singapore

We report our progress towards an atom-photon network using cavity QED. Our system utilizes a far detuned optical lattice to transfer atoms into a high finesse cavity and permits us to load single atoms in a deterministic way. In addition, a secondary dipole force trap facilitates loading atoms at very high density giving approximately 104 atoms per lattice site transferred to the cavity mode. An intra-cavity trapping laser and an additional optical lattice permit a 3-D lattice to be established in the cavity. Trapping frequencies in this geometry easily allow atoms to be cooled to the ground state. We will present our ongoing investigations with this system.
