Recent experiments towards deterministic quantum information processing with single atoms and single photons in a high-finesse optical cavity are discussed, including a single-photon server and an atom-photon interface.
We report the measurement of the population and coherence of identically prepared two-level atoms with the cavity-QED microlaser. The atomic superposition state after coherent interaction with a pump field is directly mapped to the intra-cavity photon number and frequency shift of the microlaser. Our scheme is applicable to quantum information as a tool for analyzing a two-level atomic qubit.
We propose a new type of entangled photon generation from a three-level V-type atom in a microcavity in the cavity QED scheme. In the strong-coupling regime, almost all photon pairs are entangled in polarization due to the photon blockade effect.
We consider the entanglement between a multi-level atom and two cavity modes for a cavity QED system, find that cross-correlations between the two modes are witness to atom-field entanglement. Concurrences and log negativities are also calculated.
We have observed photon blockade, as evidenced by the photon statistics for light transmitted by an optical cavity containing one trapped atom. The measurements also reveal the energy distribution for atomic motion in the trap.
Optically trapped atoms in the strong coupling regime of cavity QED have been used to generate single photons deterministically. Referenced to the total cavity output, the generation efficiency for polarized photons is 16%
We are attempting to magnetically trap cold rubidium atoms in a high-Q optical cavity for the purpose of deterministic cavity quantum electrodynamics. Recent experimental progress will be discussed, focusing on the performance and capabilities of our millimeter-scale magnetic trap
Summary form only given. One of the most interesting subfields of quantum optics is cavity QED - where microcavities impose nontrivial boundary conditions on the quantized electromagnetic field and alter the matter-light interactions of quantum electrodynamics. One of the first predictions of this theory was the modification of atomic spontaneous emission rates, through the use of microcavities to...
