Local Channels under Decomposition of Quantum Gates in Bipartite Systems
For a bipartite quantum system with Hilbert space Hm⊗Hn, this paper considers a quantum channel ϕ from the system to itself which preserves the set of separable states. Within this class of quantum channels, the paper characterizes those channels which preserve the Tsallis entropy of combinations of...
