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…
Absolute frequency measurement of the 40Ca+ S1/2 - D5/2 clock transition
M. Chwalla, J. Benhelm, K. Kim +12
We report on the first absolute transition frequency measurement at the 10^{-15} level with a single, laser-cooled 40Ca+ ion in a linear Paul trap. For this measurement, a frequenc…
Realization of the quantum Toffoli gate with trapped ions
T. Monz, K. Kim, W. Hänsel +6
Algorithms for quantum information processing are usually decomposed into sequences of quantum gate operations, most often realized with single- and two- qubit gates[1]. While such…
Nonlinear coupling of continuous variables at the single quantum level
C. F. Roos, T. Monz, K. Kim +4
We experimentally investigate nonlinear couplings between vibrational modes of strings of cold ions stored in linear ion traps. The nonlinearity is caused by the ions' Coulomb inte…
Process tomography of ion trap quantum gates
M. Riebe, K. Kim, P. Schindler +7
A crucial building block for quantum information processing with trapped ions is a controlled-NOT quantum gate. In this paper, two different sequences of laser pulses implementing…
