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.

Chers,

William
