    Aleks Kissinger has contacted me about his aims to start a collection of nLab entries on quantum information from the point of view of the Bob Coecke school.

    Being very much delighted about this offer, I created a template entry quantum information for his convenience.

    Aleks started adding some text. I added some links to his keywords.

    I've made one or two additions and suggestions. We should probably be careful to make sure that anything that isn't specifically information-theoretic goes under the quantum mechanics heading since, as Zoran pointed out about my quantum channels entry, some things that we QI people may assume are purely QI-related may actually be more general.

    Actually I've noticed that here the practice is that as long as the further generality is noted on the more specific page, the material can be duplicated on both pages (Urs is adept at this :) Corralling material into very specific pages needs to be balanced against making people jump through many links to find related information.

    Also, pages can be developed to be broad, and then split later, and I think that it is better to put any (appropriate) material in, than worry about the finer points of disciplinary delineation.

    But this is just my impression of how things go.

    OK, cool. Then I won't worry too much about it.

    yes, often only after a bunch of material has accumulated does it become clear how that material wants to be organized over different sections and maybe entries.

    of course somebody who cares and has the energy to deal with it has still to be around then...

    that said: I agree with Zoran and Ian, that we should try not to exclusively list under "quantum information" what genuinely belogs to quantum mechanics in general.

    Having looked at the entry, I see your point Ian. _I_ wouldn't go into too much more detail than what is there now (only my own opinion). Familiarity with the appropriate level of background/back up information will come with time.

    I am about to split off quantum computing from quantum information (or rather: remove the redirect, since there is nothing yet to splitt off).

    First I am hereby moving an old and forgotten query boxes from there to here :

    [ begin forwarded text ]

    +–{: .query} Ian Durham: Should we maybe somehow link the quantum mechanics section to this? Teleportation and entanglement, to me, are quantum phenomena that transcend their use in quantum information theory (the others, I agree, are purely information-theoretical).

    Aleks Kissinger: Entanglement I agree with, though the description of teleportation as a protocol (as opposed to a phenomenon) probably belongs here.

    Ian Durham: Yes, I’d agree with that. It’s description is usually in terms of a protocol. Actually, I suppose it’s status as a “phenomenon” is somewhat debatable. =–
