Sending Encrypted Message Using "Spooky" Photons.

Alex

Anton Zeilinger from the University of Vienna and an international team of scientists have managed to send an encrypted message instantaneously across 140 km between two Spanish islands using quantum physics:

The photons they sent were linked together through a process known as quantum entanglement.

This means that their properties remained tightly entwined or entangled, even when separated by large distances, a property Einstein called spooky.

The group's achievement is important for the emerging field of quantum cryptography, which aims to use properties such as entanglement to send encrypted messages.

Y'know, this means that Jacques Toussaint Benoit got the right idea in the late 1800s. If he only used photons instead of snails ...

This is being massively misinterpreted, there's no instantaneous communication going on here, just plain old lightspeed lasers. Anton and his team are working on quantum cryptography. Quantum entangled communication lasers that should be immune to eavesdropping, as it is theoretically impossible to intercept the beam without breaking the entanglement.

It's definitely for real pld. This guy was a plenary speaker at a the AIP (aus. institute of physics) congress in Brisbane, Australia about a week ago. He mentioned that if they can get the effect working over a slightly longer distance (maybe 200km) they'll be able to comunicate with satelites.

All I heard was particles, atoms and frequencies and didn't understand any of it. But I'm a bit dumb :P. Although I did think of the multiverse theory when I was 7, without ever hearing of it before - not kidding.

I thought it was pretty good. We're talking bout trying to explain what's widely accepted as the most advanced and accurate model of Physical Science... and do it in 2 minutes.

I mean, come on. If you think it's not that hard, or if you think this particular video was done poorly, why
don't you give this little experiment a try:

Try to explain to a 45yr old man or woman how to play Madden 2007 football on the X-Box Console in 2 minutes. Maybe that will help put in to perspective for you the difficulty with which the above video must have been conceived.

i dont think they are moving beyond string theory (m-theory) but there is frustration because you can't test it yet, so some believe it is a waste of time. i think that a lot of it is based on it trying to be the "theory of everything"--think it scares some people
