Quantum Telecloning Demonstrated?

An anonymous reader writes "According to Physorg eavesdropping on a quantum encrypted link can now be done without detection. From the article: 'The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement - multipartite entanglement.' There is also a PDF of a related paper available here for background material."

What it all really means

[Anonymous Coward]

What it means is that never-discussed capabilities of submarines to tap fibre optic cables at the bottom of the ocean is true.

You can tap fibre without the other party knowing. What I question, is how long has this been known at the NSA?

I hear the faint wisper of black helicopers in the distance. NOT AGAIN!!!!

NO CARRIER
