Originally posted by NewScientist.comThe technique could lead to the development of long-distance optical-quantum communications channels. These promise flawless privacy, because any attempt at eavesdropping will disturb the quantum nature of the information sent.
Currently, photons carrying quantum information can only travel tens of kilometres through fibre optics cables before deteriorating. But a "quantum repeater" capable of storing a photon's quantum information before retransmitting it, could be used to transmit quantum data over much greater distances.

If anybody can tell me, I would like to know why they believe that they can have "quantum repeaters" without it being used to sniff these quantum packets undetected? (flawless privacy = bullshit)
