Quantum nature of a strongly-coupled single quantum dot-cavity system
K. Hennessy, A. Badolato, M. Winger +6
Cavity quantum electrodynamics (QED) studies the interaction between a quantum emitter and a single radiation-field mode. When an atom is in strong coupling with a cavity mode1,2,…
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…
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 $^…
Coherence of qubits based on single Ca ions
F. Schmidt-Kaler, S. Gulde, M. Riebe +7
Two-level ionic systems, where quantum information is encoded in long lived states (qubits), are discussed extensively for quantum information processing. We present a collection o…
Experiments towards quantum information with trapped Calcium ions
D. Leibfried, C. Roos, P. Barton +8
Ground state cooling and coherent manipulation of ions in an rf-(Paul) trap is the prerequisite for quantum information experiments with trapped ions. With resolved sideband coolin…
Sympathetic ground state cooling and coherent manipulation with two-ion-crystals
H. Rohde, S. T. Gulde, C. F. Roos +5
We have cooled a two-ion-crystal to the ground state of its collective modes of motion. Laser cooling, more specific resolved sideband cooling is performed sympathetically by illum…
