Landau-Zener transitions in a qubit periodically driven in both longitudinal and transverse directions
A. B. Tchapda, M. B. Kenmoe, A. D. Kammogne +1
We theoretically investigate the dynamics of a spin-qubit periodically driven in both longitudinal and transverse directions by two classical fields respectively a radio-frequency…

Dynamics of entanglement and state-space trajectories followed by a system of four-qubit in the presence of random telegraph noise: common environment (CE) versus independent environments (IEs)
L. T. Kenfack, M. Tchoffo, M. N. Jipdi +2
The paper investigates the dynamics of entanglement and explores some geometrical characteristics of the trajectories in state space, in four-qubit Greenberger-Horne-Zeilinger (GHZ…

Compared study of Shannon, Tsallis and Gaussian entropy of bound magnetopolaron in nanostructures
M. Tiotsop, A. J. Fotue, H. B. Fotsin +1
Many methods have been experimented to study decoherence in nanostructures. Tsallis, Shannon and Gaussian entropy have been used to study decoherence separately; in this paper, we…
