Generalized Shemesh criterion, common invariant subspaces and irreducible completely positive superoperators

Andrzej Jamiołkowski, Grzegorz Pastuszak

Assume that $A_{1}, ..., A_{s}$ are complex $n \times n$ matrices. We give a computable criterion for existence of a common eigenvector of $A_{i}$ which generalize the result of D. Sh…
