Ultrahigh finesse Fabry-Pérot superconducting resonator
Applied Physics Letters 90, (2007)
The authors have built a microwave Fabry-Perot resonator made of diamond-machined copper mirrors coated with superconducting niobium. …
Quantum jumps of light recording the birth and death of a photon in a cavity
Nature 446, 297–300 (2007)
A microscopic quantum system under continuous observation exhibits at random times sudden jumps between its states. The detection of …
A cavity-QED scheme for Heisenberg-limited interferometry
Journal of Modern Optics 54, 1551–1567 (2007)
We propose a Ramsey interferometry experiment using an entangled state of N atoms to approach the Heisenberg limit for the estimation …
Analysis of dephasing mechanisms in a standing-wave dipole trap
Physical Review A 72, (2005)
We study in detail the mechanisms causing dephasing of hyperfine coherences of cesium atoms confined by a far-off-resonant …
Submicrometer position control of single trapped neutral atoms
Physical Review Letters 95, (2005)
We optically detect the positions of single neutral cesium atoms stored in a standing wave dipole trap with a subwavelength resolution …
Adiabatic quantum state manipulation of single trapped atoms
Physical Review A 71, (2005)
We use microwave-induced adiabatic passages for selective spin flips within a string of optically trapped individual neutral Cs atoms. …
Application of electro-optically generated light fields for Raman spectroscopy of trapped cesium atoms
Applied Physics B: Lasers and Optics 78, 711–717 (2004)
We present an apparatus for generating a multi-frequency laser field to coherently couple the F=3 and F=4 ground state of trapped …
Continued imaging of the transport of a single neutral atom
Optics Express 11, 3498–3502 (2003)
We have continuously imaged the controlled motion of a single atom as well as of a small number of distinguishable atoms with …
Coherence properties and quantum state transportation in an optical conveyor belt
Physical Review Letters 91, (2003)
We have prepared and detected quantum coherences of trapped cesium atoms with long dephasing times. Controlled transport by an …
Single atoms in a standing-wave dipole trap
Physical Review A 67, (2003)
We trap a single cesium atom in a standing-wave optical dipole trap. Special experimental procedures, designed to work with single …
