摘 要：This paper examines the stability of quantum feedback *** introduce a novel characterization,in terms of equivalence classes of operators,that may be used to describe open quantum *** this characterization,equivalence classes of operators are shown to be elements of a Banach space such that the norm of an operator is analogous to the root mean square expectation value of the *** characterization is ideally suited to describing quantum feedback systems and enables us to prove the uniqueness and existence of solutions for feedback *** this context,we prove a quantum version of the small-gain theorem that is a generalisation of the classical small gain theorem.
