Positive Maps From Irreducibly Covariant Operators
Piotr Kopszak, Marek Mozrzymas, Michał Studziński
In this paper, we discuss positive maps induced by (irreducibly) covariant linear operators for finite groups. The application of group theory methods allows deriving some new resu…
Quantum error correction codes and absolutely maximally entangled states
Paweł Mazurek, Máté Farkas, Andrzej Grudka +2
For every stabiliser -qudit absolutely maximally entangled state, we present a method for determining the stabiliser generators and logical operators of a corresponding quantum…
A Class of PPT Entangled States Arbitrary Far From Separable States
Adam Rutkowski, Michał Studziński
In this paper we show an explicit construction of multipartite class of entangled states with the PPT (Positive Partial Transposition) property in every cut. We investigate propert…
