Fixed points of quantum operations
WebA quantum operation is defined as ε ( ρ) = ∑ k M k ρ M k † where ε ( ρ) takes an initial state ρ to some final state ρ ′ and M k † M k 's are positive, contractive operators that satisfy ∑ k M k † M k = I. It is known through Schauder's fixed point theorem that this admits a … WebQuantum operations frequently occur in quantum measurement theory, quantum probability, quantum computation, and quantum information theory.
