On decoherence induced by a spin chain: role of initial prepared states
L. T. Kenfack, M. R. T. Fokou, M. Tchoffo +2
We study the decoherence process induced by a spin chain environment on a central spin consisting of R spins and we apply it on the dynamics of quantum correlations (QCs) of three…

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…

Path Integral approach to kinematical browmian motion, due to random canonical transformation
M. Tchoffo, A. A. Belinson
The stochastization of the Jacobi second equality of classical mechanics, by Gaussian white noises for the Lagrangian of a particle in an arbitrary field is considered. The quantum…
