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…

Quantum interference from remotely trapped ions
S. Gerber, D. Rotter, M. Hennrich +7
We observe quantum interference of photons emitted by two continuously laser-excited single ions, independently trapped in distinct vacuum vessels. High contrast two-photon interfe…
