Cavity QED is a promising platform for quantum technologies because it
allows photons, which can easily propagate over long distances, to interact
strongly with atoms, which are natural qubits with excellent coherence
properties. We have recently developed a technique for trapping a single
rubidium atom in the evanescent mode of a nano-fabricated optical cavity
with sub-wavelength dimensions . By virtue of their small size, these
cavities provide extremely large atom-photon coupling strengths and good
prospects for scalability and integration into complex quantum optical
circuits. As a first application, we have demonstrated a coherent optical
switch, where a single ?gate? photon controls the propagation of many
subsequent ?signal? photons, with the interaction mediated by the atom and
cavity . Additionally, I will discuss ongoing work to implement
multi-atom quantum gates and to produce exotic non-classical states of

Jeff Thompson works on nanofabricated atom traps in the lab of
Professor Mikhail Lukin. Prior to coming to Harvard, Jeff received his
BS from Yale University, where he also performed experiments on
laser-cooling mechanical systems with Jack Harris. After graduating,
he spent a year working with ultracold atoms in optical lattices in
the group of Immanuel Bloch in Mainz, Germany.
