Check out this month's Discover for an article on using quantum
mechanics to generate a completely random bit-encryption key for two
parties.  Using a new key for each message makes it virtually
uncrackable.  The slick part is that if a third party tries to
intercept the key, the quantum effects guarantee that they can't get
it without affecting the recieved keys.  They've got a working model
that runs up to 200 feet.  Not very practical, but enough to show that
it works.
