Stratified Manifold of Quantum States, actions of the complex special linear group
Dariusz Chruscinski, Florio M. Ciaglia, Alberto Ibort +2
We review the geometry of the space of quantum states of a finite-level quantum system with Hilbert space from a group-theoretical point of…
A possible time dependent generalization of the bipartite quantum marginal problem
Giuseppe Baio, Dariusz Chruscinski, Antonino Messina
In this work we study an inverse dynamical problem for a bipartite quantum system governed by the time local master equation: to find the class of generators which give rise to a c…
Universal spectra of random Lindblad operators
Sergey Denisov, Tetyana Laptyeva, Wojciech Tarnowski +2
To understand typical dynamics of an open quantum system in continuous time, we introduce an ensemble of random Lindblad operators, which generate Markovian completely positive evo…
Quantum entropy and non-Markovian evolution
Paolo Aniello, Joonwoo Bae, Dariusz Chruscinski
Entropy, and its temporal evolution, play a central role in the foundations of quantum theory and in modern quantum technologies. Here we study, in particular, the relations betwee…
More entanglement implies higher performance in tailored channel discrimination tasks
Joonwoo Bae, Dariusz Chruściński, Marco Piani
We show that every entangled state provides an advantage in bi- and multi-channel discrimination that singles out its degree of entanglement, quantified in terms of its Schmidt num…
Generalizing Choi-like maps
Dariusz Chruściński, Marcin Marciniak, Adam Rutkowski
A problem of further generalization of generalized Choi maps acting on introduced by Cho, Kye and Lee is discussed. Some necessary conditions for posit…
