Probability representation of quantum dynamics using pseudostochastic maps
E. O. Kiktenko, A. O. Malyshev, A. S. Mastiukova +3
In this work, we consider a probability representation of quantum dynamics for finite-dimensional quantum systems with the use of pseudostochastic maps acting on true probability d…

Bounds on bipartite entanglement from fixed marginals
Giuseppe Baio, Dariusz Chruscinski, Pawel Horodecki +2
We discuss the problem of characterizing upper bounds on entanglement in a bipartite quantum system when only the reduced density matrices (marginals) are known. In particular, sta…
