Measuring the internal state of a single atom without energy exchange
Jürgen Volz, Roger Gehr, Guilhem Dubois +2
Real quantum measurements almost always cause a much stronger back action than required by the laws of quantum mechanics. In particular, free-space optical detection methods for si…
Cavity-based single atom preparation and high-fidelity hyperfine state readout
Roger Gehr, Jürgen Volz, Guilhem Dubois +6
We prepare and detect the hyperfine state of a single 87Rb atom coupled to a fiber-based high finesse cavity on an atom chip. The atom is extracted from a Bose-Einstein condensate…
Strong atom-field coupling for Bose-Einstein condensates in an optical cavity on a chip
Yves Colombe, Tilo Steinmetz, Guilhem Dubois +3
An optical cavity enhances the interaction between atoms and light, and the rate of coherent atom-photon coupling can be made larger than all decoherence rates of the system. For s…
Electronic transport in quantum cascade structures
C. Koeniguer, G. Dubois, A. Gomez +1
The transport in complex multiple quantum well heterostructures is theoretically described. The model is focused on quantum cascade detectors, which represent an exciting challenge…
