Chris Fuchs, the leading expert on the foundation of quantum mechanics, comments on the veil of secrecy descending on quantum crypto in a 2002 PC Magazine article. Here is a quote from the article: "Drawing on the seemingly magical principles of quantum mechanics—the physics associated with very small particles—it allows two people to exchange encryption keys over a public network, use those keys to encode their correspondence, and know that the correspondence is completely secure." I am sure that Chris Fuchs does not believe that quantum crypto is "magic". It is not magic and it is deterministic.
