Robust "trapping states" in the motion of a trapped ion
S. Wallentowitz, W. Vogel, P. E. Toschek
A novel robust mechanism for the generation of "trapping states" is shown to exist in the coupling of a two-level system with an oscillator, which is based on nonlinearities in the…
Quantum Limits of Stochastic Cooling of a Bosonic Gas
D. Ivanov, S. Wallentowitz, I. A. Walmsley
The quantum limits of stochastic cooling of trapped atoms are studied. The energy subtraction due to the applied feedback is shown to contain an additional noise term due to atom-n…
How big is a quantum computer?
S. Wallentowitz, I. A. Walmsley, J. H. Eberly
Accounting for resources is the central issue in computational efficiency. We point out physical constraints implicit in information readout that have been overlooked in classical…
