Precision preparation of strings of trapped neutral atoms
Y. Miroshnychenko, W. Alt, I. Dotsenko +4
We have recently demonstrated the creation of regular strings of neutral caesium atoms in a standing wave optical dipole trap using optical tweezers [Y. Miroshnychenko et al., Natu…
Analysis of dephasing mechanisms in a standing wave dipole trap
S. Kuhr, W. Alt, D. Schrader +4
We study in detail the mechanisms causing dephasing of hyperfine coherences of cesium atoms confined by a far off-resonant standing wave optical dipole trap [S. Kuhr et al., Phys.…
Quantum Rabi oscillations in coherent and in mesoscopic Schrödinger "cat" field states
F. Assemat, D. Grosso, A. Signoles +6
The simple resonant Rabi oscillation of a two-level system in a single-mode coherent field reveals complex features at the mesoscopic scale, with oscillation collapses and revivals…
Field locked to Fock state by quantum feedback with single photon corrections
X. Zhou, I. Dotsenko, B. Peaudecerf +6
Fock states with photon numbers n up to 7 are prepared on demand in a microwave superconducting cavity by a quantum feedback procedure which reverses decoherence-induced quantum ju…
Adiabatic Quantum State Manipulation of Single Trapped Atoms
M. Khudaverdyan, W. Alt, I. Dotsenko +6
We use microwave induced adiabatic passages for selective spin flips within a string of optically trapped individual neutral Cs atoms. We position-dependently shift the atomic tran…
Coherence properties and quantum state transportation in an optical conveyor belt
S. Kuhr, W. Alt, D. Schrader +7
We have prepared and detected quantum coherences with long dephasing times at the level of single trapped cesium atoms. Controlled transport by an "optical conveyor belt" over macr…
