Simulations of Quantum Logic Operations in Quantum Computer with Large Number of Qubits

G. P. Berman, G. D. Doolen, G. V. Lopez +1

We report the first simulations of the dynamics of quantum logic operations with a large number of qubits (up to 1000). A nuclear spin chain in which selective excitations of spins…

Non-Resonant Effects in Implementation of Quantum Shor Algorithm

G. P. Berman, G. D. Doolen, G. V. Lopez +1

We simulate Shor's algorithm on an Ising spin quantum computer. The influence of non-resonant effects is analyzed in detail. It is shown that our ``''-method successfully supp…

Influence of Non-Resonant Effects on the Dynamics of Quantum Logic Gates at Room Temperature

G. P. Berman, A. R. Bishop, G. D. Doolen +2

We study numerically the influence of non-resonant effects on the dynamics of a single -pulse quantum CONTROL-NOT (CN) gate in a macroscopic ensemble of fo ur-spin molecules at…

Unbroken supersymmetry in the Aharonov-Casher effect

S. Bruce et. al

We consider the problem of the bound states of a spin 1/2 chargless particle in a given Aharonov-Casher configuration. To this end we recast the description of the system in a supe…

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…
