Now that Snowden has released docs indicting the NSA can crack most regular encryption (like TOR), and most likely can, or will soon, crack most everything, this may be our only hope of reclaiming our communication privacy. Eventually. It harnesses the bizarro-world properties of quantum physics to ensure that information sent from point A to point B isnt intercepted. The laws of physics dictate that nobodynot even the NSAcan measure a quantum system without disrupting it.

This kind of communication cannot be defeated by future advances in computing power, nor new mathematical algorithms, nor fancy new engineering, said co-author Andrew Shields, head of the Quantum Information Group of Toshiba Research Europe. As long as the laws of physics hold true, it will ensure that your communications are fully secured.
