Dynamical creation of entanglement versus disentanglement in a system of three - level atoms with vacuum - induced coherences
L. Derkacz, L. Jakobczyk
The dynamics of entanglement between three - level atoms coupled to the common vacuum is investigated. We show that the collective effects such as collective damping, dipole - dipo…
Vacuum - induced stationary entanglement in radiatively coupled three - level atoms
L. Derkacz, L. Jakobczyk
We consider a pair of three - level atoms interacting with a common vacuum and analyze the process of entanglement production due to spontaneous emission. We show that in the case…
Entanglement of a class of mixed two - qutrit states
L. Derkacz, L. Jakobczyk
We compute the measure of entanglement for some classes of states belonging to the simplex of Bell - diagonal states of two qutrits.
Quantum interference and evolution of entanglement in a system of three-level atoms
L. Derkacz, L. Jakobczyk
We consider a pair of three-level atoms interacting with the vacuum. The process of disentanglement due to spontaneous emission and the role of quantum interference between princip…
CHSH violation and entropy - concurrence plane
L. Derkacz, L. Jakobczyk
We characterize violation of CHSH inequalities for mixed two-qubit states by their mixedness and entanglement. The class of states that have maximum degree of CHSH violation for a…
Generation of Werner states and preservation of entnglement in a noisy environment
L. Jakobczyk, A. Jamroz
We study the influence of noisy environment on the evolution of two-atomic system in the presence of collective damping. Generation of Werner states as asymptotic states of evoluti…
