Raman spectroscopy of a single ion coupled to a high-finesse cavity
C. Russo, H. G. Barros, A. Stute +9
We describe an ion-based cavity-QED system in which the internal dynamics of an atom is coupled to the modes of an optical cavity by vacuum-stimulated Raman transitions. We observe…
How to realize a universal quantum gate with trapped ions
F. Schmidt-Kaler, H. Häffner, M. Riebe +7
We report the realization of an elementary quantum processor based on a linear crystal of trapped ions. Each ion serves as a quantum bit (qubit) to store the quantum information in…
Vacuum-field level shifts in a single trapped ion mediated by a single distant mirror
M. A. Wilson, P. Bushev, J. Eschner +4
A distant mirror leads to a vacuum-induced level shift in a laser-excited atom. This effect has been measured with a single mirror 25 cm away from a single, trapped barium ion. Thi…
Precision measurement and compensation of optical Stark shifts for an ion-trap quantum processor
H. Haeffner, S. Gulde, M. Riebe +5
Using optical Ramsey interferometry, we precisely measure the laser-induced AC-stark shift on the -- "quantum bit" transition near 729 nm in a single trapped $^…
Coupling a single atomic quantum bit to a high finesse optical cavity
A. B. Mundt, A. Kreuter, C. Becher +4
The quadrupole S -- D optical transition of a single trapped Ca ion, well suited for encoding a quantum bit of information, is coherently coupled to the standin…
