Ambiguities on the quantization of a one-dimensional dissipative system with position depending dissipative coefficient
Gustavo Lopez, Xaman-Ek Lopez, Gabriel Gonzalez
For a one-dimensional dissipative system with position depending coefficient, two constant of motion are deduce. These constants of motion bring about two Hamiltonians to describe…
Effects on the eigenvalues of the quantum bouncer due to dissipation
G. Lopez, G. Gonzalez
Effects on the spectra of the quantum bouncer due to dissipation are given when a linear or quadratic dissipation is taken into account. Classical constant of motions and Hamiltoni…
Qubitless Quantum Logic
Richard B. Kassman, Gennady P. Berman, Vladimir I. Tsifrinovich +1
We discuss the implementation of quantum logic in a system of strongly interacting particles. The implementation is qubitless since ``logical qubits'' don't correspond to any physi…
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…
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…
