I don't see the point of communicating by entangled
photon pairs, I must admit. In terms of cryptography,
that's snake oil. Throughput is awful (single-photon
sources) even over short distances, and so is 
susceptibility to disturbances.

So what is the point of quantum communication over
long distances? (I would see the point for short
distances, for QC).
