Quantum Data

How exciting!  It seems to me that the kind of technology that might enhance surveillance,  but that also allows secure espionage, both of which this article specifically describes, would allow for a large range of uses in the non-military world.  Maybe it would be possible to use this technology to avoid be spied on, NSA-style.

From the Atlantic:

…physicists agree that transmitting quantum information, though possible, is unstable. And yet! The U.S. Army Research Laboratory today announced its own quantum breakthrough.

A team at the lab’s Adelphi, Maryland, facility says it has developed a prototype information teleportation network system based on quantum teleportation technology. The technology can be used, the Defense Department says, to transmit images securely, either over fiber optics or through space—that is, teleportation in which data is transmitted wirelessly.

The DoD says it can imagine using this kind of technology so military service members can securely transmit intelligence—photos of from “behind enemy lines,” for instance—back to U.S. officials without messages being intercepted.

But this kind of technological advance, especially in a government-run lab, is significant for the rest of us, too. Quantum computing would offer unprecedented upgrades to data processing—both in speed and scope—which could enhance surveillance technologies far beyond what exists today.

“That’s why the NSA in particular is so interested in quantum computers and would like to have one,” the physicist Steve Rolston told me last week, “and probably would not tell anyone if they did.”
