Perturbation Theory and Numerical Modeling of Quantum Logic Operations with a Large Number of Qubits
G. P. Berman, G. D. Doolen, D. I. Kamenev +2
The perturbation theory is developed based on small parameters which naturally appear in solid state quantum computation. We report the simulations of the dynamics of quantum logic…
Control of Non-Resonant Effects in a Nuclear Spin Quantum Computer with a Large Number of Qubits
G. P. Berman, G. D. Doolen, D. I. Kamenev +1
We discuss how to simulate simple quantum logic operations with a large number of qubits. These simulations are needed for experimental testing of scalable solid-state quantum comp…
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…
Quantum Entangled States and Quasiclassical Dynamics in Macroscopic Spin Systems
Gennady P. Berman, Gary D. Doolen, Gustavo V. Lopez +1
When dealing with macroscopic objects one usually observes quasiclassical phenomena, which can be described in terms of quasiclassical (or classical) equations of motion. Recent de…
