There are existing quantum encryption algorithms that require a physical link between the communicators (and don't provide authentication) -- these are used in the products sold by ID Quantique. But it hasn't been established that an encryption algorithm needs to be based on quantum mechanisms to survive the introduction of quantum computers. So I'd take issue with your phrasing of the question. In so far as you're wondering about what algorithms will be used in the post-quantum computing world, the ECRYPT project has organized a workshop on postquantum cryptography -- see http://postquantum.cr.yp.to/ for details. The report of that workshop should be interesting reading.
