Constraints for the spectra of generators of quantum dynamical semigroups

Dariusz Chruscinski, Ryohei Fujii, Gen Kimura +1

Motivated by a spectral analysis of the generator of completely positive trace-preserving semigroup, we analyze a real functional $$ A,B \in M_n(\mathbb{C}) \to r(A,B) = \frac{1}{2…
