Abelian and non-Abelian geometric phases in adiabatic open quantum systems
M. S. Sarandy, D. A. Lidar
We introduce a self-consistent framework for the analysis of both Abelian and non-Abelian geometric phases associated with open quantum systems, undergoing cyclic adiabatic evoluti…
Extended Cahill-Glauber formalism for finite dimensional spaces: I. Fundamentals
M. Ruzzi, M. A. Marchiolli, D. Galetti
The Cahill-Glauber approach for quantum mechanics on phase-space is extended to the finite dimensional case through the use of discrete coherent states. All properties and features…
Quantum NOT Operation and Integrability in Two-Level Systems
Renato M. Angelo, Walter F. Wreszinski
We demonstrate the surprising integrability of the classical Hamiltonian associated to a spin 1/2 system under periodic external fields. The one-qubit rotations generated by the dy…
Spin & Statistics in Nonrelativistic Quantum Mechanics, II
Bernd Kuckert, Jens Mund
Recently a sufficient and necessary condition for Pauli's spin- statistics connection in nonrelativistic quantum mechanics has been established [quant-ph/0208151]. The two-dimensio…
Tunneling as a classical escape rate induced by the vacuum zero-point radiation
A. J. Faria, H. M. Franca, R. C. Sponchiado
We make a brief review of the Kramers escape rate theory for the probabilistic motion of a particle in a potential well U(x), and under the influence of classical fluctuation force…
Engineering superpositions of displaced number states of a trapped ion
Marcelo A. Marchiolli, Wagner D. Jose
We present a protocol that permits the generation of a subtle with superposition with 2^(l+1) displaced number states on a circle in phase space as target state for the center-of-m…
