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…
