Non-decomposable quantum dynamical semigroups and bound entangled states
Fabio Benatti, Roberto Floreanini, Marco Piani
We use open quantum system techniques to construct one-parameter semigroups of positive maps and apply them to study the entanglement properties of a class of 16-dimensional densit…

Complete positivity and dissipative factorized dynamics: some comments
F. Benatti, R. Floreanini, M. Piani +1
After reviewing the main properties of time-evolutions of open quantum systems, some considerations about the positivity of factorized Markovian dynamics for bipartite systems are…
