Chaos and ergodicity in an entangled two-qubit Bohmian system
Athanasios C. Tzemos, George Contopoulos
We study in detail the onset of chaos and the probability measures formed by individual Bohmian trajectories in entangled states of two-qubit systems for various degrees of entangl…
Bohmian trajectories in an entangled two-qubit system
Athanasios Tzemos, George Contopoulos, Christos Efthymiopoulos
In this paper we examine the evolution of Bohmian trajectories in the presence of quantum entanglement. We study a simple two-qubit system composed of two coherent states and inves…
Chaos in de Broglie - Bohm quantum mechanics and the dynamics of quantum relaxation
Christos Efthymiopoulos, George Contopoulos, Athanasios C. Tzemos
We discuss the main mechanisms generating chaotic behavior of the quantum trajectories in the de Broglie - Bohm picture of quantum mechanics, in systems of two and three degrees of…
Partial Integrability of 3-d Bohmian Trajectories
George Contopoulos, Athanasios C. Tzemos, Christos Efthymiopoulos
In this paper we study the integrability of 3-d Bohmian trajectories of a system of quantum harmonic oscillators. We show that the initial choice of quantum numbers is responsible…
Dependence on state preparation of noise induced effects in multiqubit systems
A. C. Tzemos, D. P. K. Ghikas
The perturbation of multiqubit systems by an external noise can induce various effects like decoherence, stochastic resonance and anti-resonance, and noise-shielding. We investigat…
Entangling and decohering influence of noisy perturbations. Stochastic anti-resonance in the time evolution of interacting qubits
Demetris P. K. Ghikas, Athanasios C. Tzemos
We study the entanglement evolution of two coupled qubits in interaction with an external environment and in the presence of an external magnetic field with a stochastic component.…
