Correct me if I'm wrong, but isn't this extremely bad? Don't they realize
the system fails if they send more than one photon? the redundancy allows an
attacker with sensitive equipment to read a single photon (or maybe a few)
without the receiving end noticing! (Due to their fancy less-sensitive,
error correcting receiver) This renders the whole system completely useless
for cryptographic purposes.

Hope they didn't spend too much money developing it.
