Dynamical Stability of an Ion in a Linear Trap as a Solid-State Problem of Electron Localization
G. P. Berman, A. R. Bishop, D. F. V. James +2
When an ion confined in a linear ion trap interacts with a coherent laser field, the internal degrees of freedom, related to the electron transitions, couple to the vibrational deg…
Observation of power-law scaling for phase transitions in linear trapped ion crystals
D. G. Enzer, M. M. Schauer, J. J. Gomez +10
We report an experimental confirmation of the power-law relationship between the critical anisotropy parameter and ion number for the linear-to-zigzag phase transition in an ionic…
Dynamical Stability and Quantum Chaos of Ions in a Linear Trap
G. P. Berman, D. F. V. James, R. J. Hughes +3
The realization of a paradigm chaotic system, namely the harmonically driven oscillator, in the quantum domain using cold trapped ions driven by lasers is theoretically investigate…
Decoherence Bounds on Quantum Computation with Trapped Ions
Richard J. Hughes, Daniel F. V. James, Emanuel H. Knill +2
Using simple physical arguments we investigate the capabilities of a quantum computer based on cold trapped ions. From the limitations imposed on such a device by spontaneous decay…
