Photon Pair Coupled in Glass Fiber

Trachman writes: Austrian scientists have discovered a way to couple photon pairs. When two identical photons are coupled and the phase of one is changed, then thanks to the magic of quantum mechanics, the phase of the other photon also changes (abstract). Scientists predict this can advance quantum optics and quantum computations, taking us a step closer to having data transmissions secure from the nosy agencies of the world.

If any of you have expertise in this area, could you share your thoughts on the essence of this discovery and its associated potential practical applications?

Step 1. invent new process that *potentially* could thwart nosy droppers of eaves
Step 2. Process is so expensive and difficult to implement, said agencies are likely to be the only users.
Step 3. Post to slashdot.
People need to wake up and realize that privacy is dead, and ubiquitous violations of personal privacy will soon become the norm.
Your grandchildren will think you a bit 'off' for being of the opinion that privacy is a good thing.
