Group representation approach to 1 - N universal quantum cloning machines
Michał Studziński, Piotr Ćwikliński, Michał Horodecki +1
In this work, we revisit the problem of finding an admissible region of fidelities obtained after an application of an arbitrary universal quantum cloner which ha…
Structure and properties of the algebra of partially transposed permutation operators
Marek Mozrzymas, Michał Horodecki, Michał Studziński
We consider the structure of algebra of operators, acting in fold tensor product space, which are partially transposed on the last term. Using purely algebraical methods we sho…
Commutant structuture of Ux...xUxU* transformations
Michał Studziński, Michał Horodecki, Marek Mozrzymas
In this paper we have found irreducible representations (irreps) of the algebra of partially transposed permutation operators on last subsystem. We give here direct method of irrep…
