Single-atom-resolved fluorescence imaging of an atomic Mott insulator
Nature 467, 68–72 (2010)
The reliable detection of single quantum particles has revolutionized the field of quantum optics and quantum information processing. …
Quantum field state measurement and reconstruction in a cavity by quantum nondemolition photon counting: 19th International Conference on Laser Spectroscopy
158–168 (2010)
Quantum nondemolition photon (QND) counting in a high Q cavity is performed by using circular Rydberg atoms. The atoms behave as clocks …
Electromagnetically induced transparency and light storage in an atomic Mott insulator
Physical Review Letters 103, (2009)
We experimentally demonstrate electromagnetically induced transparency and light storage with ultracold Rb-87 atoms in a Mott …
Process tomography of field damping and measurement of fock state lifetimes by quantum nondemolition photon counting in a cavity
Physical Review Letters 101, (2008)
The relaxation of a quantum field stored in a high-Q superconducting cavity is monitored by nonresonant Rydberg atoms. The field, …
Freezing coherent field growth in a cavity by the quantum zeno effect
Physical Review Letters 101, (2008)
We have frozen the coherent evolution of a field in a cavity by repeated measurements of its photon number. We use circular Rydberg …
Progressive field-state collapse and quantum non-demolition photon counting
Nature 448, 889–893 (2007)
The irreversible evolution of a microscopic system under measurement is a central feature of quantum theory. From an initial state …
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 …
