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 a related question: if several coherence transfers can be optimized separately, c…

On distilling secure key from reducible private states and (non)existence of entangled key-undistillable states
K. Horodecki, P. Ćwikliński, A. Rutkowski +1
Hereunder, we study the class of irreducible private states that are private states from which all the secret content is accessible via measuring their key part. We provide the fir…
