The Entanglement Can-n-Wire

Time for me to get my science on. It's been too long.

This will be the first bit about entanglement and quantum mechanics, but I can assure you it will not be the last. This is some fascinatin' stuff, brother.

So, via the Scientific American 60-Second-Science Blog, we see that there's been some advances on the front of measuring entanglement speed. Namely, we know that, on the low end, entanglement moves at least 10,000 times the speed of light.

3 000 000 000 000 meters per seconds. That's the old-lady-in-the-right-lane estimate.

The applications for the future of quantum research are limitless, but an easy one is in the realm of quantum cryptography. In Snowden's little hypothesis, a group with vital info, like a U.S. military group or a Swiss bank, will send their info encrypted on a photon. It will then move between the two spots, and any interception between the two points will destroy the quantum state of the photon. Any change in state, the photon is destroyed, preserving the fidelity of the communique.

So, in under 10 years, expect some trans-global transmissions to violate the theory of relativity. Neat, huh?
