This result is, in a probabilistic language, a decomposition of a general quantum channel into its irreducible positive recurrent components. This decomposition is related with a communication relation on the reference Hilbert space. This allows us to describe the full structure of invariant states of a quantum channel, and of their supports.", "revisions": [ { "version": "v1", "updated": "2015-07-30T07:11:56.000Z" } ], "analyses": { "keywords": [ "stationary states", "irreducible decompositions", "infinite dimensional case", "general quantum channel", "reference hilbert space" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150708404C" } } }
