Abstract

The project addresses two important open problems in ultracold atomic physics related to the general goals of quantum computation and quantum-limited precision measurement: (I) developing a hybrid atom-photon interferometer for quantum-limited measurements of environmental properties, and (II) developing Interaction-Free quantum gates for deterministic long distance teleportation of atomic qubits. Both problems make use of the fact that atoms are ideal qubits and/or probes of the environment,whereas photons are the best choice for transmitting quantum information.
