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…
