The US Government Has Been Running a Quantum Internet for Over Two YearsSubmitted by independent_thought on Tue, 05/07/2013 - 03:28
"It’s a perfectly secure Internet that by definition cannot be penetrated by wiretaps and eavesdropping — and the US government has been sitting on it for the last two-and-a-half years.
A longtime goal among cryptologists has been to perfect the “quantum Internet” — which, in the most basic way possible, uses the main principle of quantum mechanics to transfer communications from one point to another.
Still confused? Technology Review explained it as easily as possible:
'The basic idea here is that the act of measuring a quantum object, such as a photon, always changes it. So any attempt to eavesdrop on a quantum message cannot fail to leave telltale signs of snooping that the receiver can detect.'"
