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…
Formation and Pinch-off of Viscous Droplets in the Absence of Surface Tension: an Exact Result
Mark Mineev-Weinstein, Gary D. Doolen, John E. Pearson +1
Within a class of exact time-dependent non-singular N-logarithmic solutions (Mineev-Weinstein and Dawson, Phys. Rev. E 50, R24 (1994); Dawson and Mineev-Weinstein, Phys. Rev. E 57,…
Shock-Like Dynamics of Inelastic Gases
E. Ben-Naim, S. Y. Chen, G. D. Doolen +1
We provide a simple physical picture which suggests that the asymptotic dynamics of inelastic gases in one dimension is independent of the degree of inelasticity. Statistical chara…
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…
Dynamics of the Measurement of Nuclear Spins in a Solid-State Quantum Computer
Gennady P. Berman, David K. Campbell, Gary D. Doolen +1
We study numerically the process of nuclear spin measurement in a solid-state quantum computer of the type proposed by Kane by modeling the quantum dynamics of two coupled nuclear…
