Beyond unital noise in variational quantum algorithms: noise-induced barren plateaus and limit sets by Phattharaporn Singkanipa, Daniel A. Lidar

“…Here, we generalize the study of NIBPs to more general completely positive, trace-preserving maps, investigating the existence of NIBPs in the unital case and a class of non-unital maps we call Hilbert-Schmidt (HS)-contractive. The latter includes amplitude damping. …”
