The above description does not seem accurate -- the arrows should be *unitary* transformations or *contractions.* Otherwise, this is none other than the category of finite dimensional vector spaces.

• Actually, I added 'between them' thus, it must satisfies some properties w.r.t. the form. This (unitary maps or contraction) should be added in the 'properties' list and defined w.r.t. the dagger-monoidal structure. Moreover, discussion should *not* take place in the article but here.

Shouldn't it be _complex_ finite dimensional Hilbert spaces for it to form a monoidal category? What is the tensor unit otherwise? —Preceding unsigned comment added by Iratsu (talk • contribs) 15:52, 4 August 2009 (UTC)Reply

All of the above issues seem to have been fixed long ago. 99.153.64.179 (talk) 18:46, 27 November 2013 (UTC)Reply
