Talk:Superoperator

From Wikipedia, the free encyclopedia

[edit] suggest delete

i am sorry but i suggest this page should go. not sure the terminology is standard at all. in any case, relevant material is already discussed in Choi's theorem on completely positive maps, Stinespring factorization theorem, Quantum channel, Quantum operation, and maybe elsewhere.

or perhaps merge or redirect. in that case, some evidence that the term, certainly not common, if used at all, in the mathematically oriented literature, is in sufficiently wide use would be nice. personally i find the terminology peculiar and prefer the "linear CP map between C* algebras" description.

I'm not sure about this. It does come up a lot in the literature on quantum programming languages, usually as a denotational semantics for said languages. If it is a concept that appears in several other places, maybe it should have it's own page with a definition and links to those other pages. I have come across the term superoperator in physics literature as well, but C* algebras are usually in the domain of mathematics. Maybe super operators is only the computer science way of thinking about completely positive maps over C* algebras, but the term does exist as is used in many recent, and groundbraking, scientific papers (for example, Selinger's Towards a Quantum Programming Language. Maybe a page explaining all this would be useful, unless there is already a page doing that. If not, why not redirect as before this page super-op returned not much. I'd expand it myself but I'm a bit busy at the moment and Im not a mathematician. Thanks --82.10.215.62 20:30, 23 July 2006 (UTC)

ok, i believe you re usage of this term. Mct mht 02:25, 24 July 2006 (UTC)

Mct mht, if even you're not sure whether it should be redirected, and it's on the list of requested math articles, I don't think it qualifies as a speedy. If you want to press the issue, I'd recommend WP:AFD or merge it in somewhere else. —Wknight94 (talk) 21:00, 23 July 2006 (UTC)

You know, this page isn't what I expected too... --HappyCamper 18:40, 8 August 2006 (UTC)
