"I am not a speed reader. I am a speed understander."

| Telephony that uses quantum effects for transmission - and is therefore the ultimate in anti-eavesdropping technology. |
| After a few minutes of studying his palms, frowning deeply, he picked up his disposable cell and slipped in a new quantum card.
Then he typed in a key code and called a dummy transponder in Nicaragua. The dummy flashed his call to a number none of them knew, which passed it on - again through a quantum EPR cell - to yet another number. It took several seconds to connect to the Quiet Man. |

The "EPR" refers to the 1935 Einstein-Podolsky-Rosen thought experiment in which two particle systems interact with each other in a very particular way and are then separated. Position (let's say) is measured in one system, which then determines position in the other; momentum may then be measured in the second system, violating the uncertainty principle.
This entaglement (or "spukhafte Fernwirkung" or "spooky action at a distance" as Einstein called it) has since been proven in experiments.
It therefore follows (sfnally) that communication should be possible in such a way that it cannot possibly be intercepted (look for Sprint's "Spooky Service at a Distance" available soon!).
