Characterization of equivariant maps and application to entanglement detection

Ivan Bardet, Benoît Collins, Gunjan Sapra

We study equivariant linear maps between finite-dimensional matrix algebras, as introduced by Bhat. These maps satisfy an algebraic property which makes it easy to study their posi…

On a family of a linear maps from $M_{n} (C)$ to $M_{n^{2}} (C)$

Benoit Collins, Hiroyuki Osaka, Gunjan Sapra

Bhat characterizes the family of linear maps defined on $B (H)$ which preserve unitary conjugation. We generalize this idea and study the maps with a similar equivariance…
