Non-Markovianity degree for random unitary evolution
Dariusz Chruściński, Filip A. Wudarski
We analyze the non-Markovianity degree for random unitary evolution of d-level quantum systems. It is shown how non-Markovianity degree is characterized in terms of local decoheren…
A class of symmetric Bell diagonal entanglement witnesses - a geometric perspective
Dariusz Chruściński
We provide a class of Bell diagonal entanglement witnesses displaying an additional local symmetry -- a maximal commutative subgroup of the unitary group U(n). Remarkably, this cla…
Interaction-free evolving states of a bipartite system
A. Napoli, M. Guccione, A. Messina +1
We show that two interacting physical systems may admit entangled pure or non separable mixed states evolving in time as if the mutual interaction hamiltonian were absent. In this…
Entanglement witnesses: construction, analysis and classification
Dariusz Chruściński, Gniewomir Sarbicki
From the physical point of view entanglement witnesses define a universal tool for analysis and classification of quantum entangled states. From the mathematical point of view they…
