Finite-time quantum equilibration from local correlations
Piotr Ćwikliński
An isolated quantum system evolves reversibly, yet a small subsystem can lose nearly all information about its initial state. Conserved quantities may retain some of this informati…

Asymmetric quantum cloning on orthogonal orbits and four-mode fermionic states
Piotr Ćwikliński, Michał Studziński
In this work, we study asymmetric quantum cloning for pure states belonging to orbits generated by the orthogonal group. For every dimension , we determine the…

Limitations on Joint Coherence Transfer in Quantum Thermodynamics
Piotr Ćwikliński, Michał Studziński
Coherences between different energy levels are strongly constrained by thermodynamics. Here we ask whether several coherence transfers that can be optimized separately can also be…
