It has been experimentally demonstrated by several groups in the last year that you can use a pair of entangled states as a carrier to carry the properties of a third state to a different place, without observing them. This is the basic function of teleportation (as in StarTrek).

Encryptation based on teleportation can be shown to be secure in principle, as long as Quantum Mechanics is true.
