Reducing the cost of ancilla purification for Majorana quantum computation
Piotr Ćwikliński, Piotr {Ć}wikli{ń}ski, Łukasz Fojcik +2
Braiding Majorana zero modes does not by itself provide a universal set of quantum gates. Additional operations can be supplied through ancillary states, whose preparation need not…

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…
