Wireless Communication via Neutrinos
« on: July 02, 2012, 07:03:29 PM »
I posted this in the comments for "Episode 13: That Which Lies Beneath The Ice"...  Figured it could use it's own thread here.

“Researchers Send “Wireless” Message Using Elusive Particles”

http://www.rochester.edu/news/show.php?id=4022

Granted, the equipment needed is pretty unwieldy at the moment but it’s progress! 

Also good to see that Fermilab is still making scientific waves despite the shutdown of their atom smasher, er, particle accelerator.

maybe they could use flavour mixing as a way to encode what they're trying to say.
Titanium Physicists has a pro-bee-analogy agenda. That's certainly no secret.

With what my cable company charges for a compatible cable modem, maybe I should just by an accelerator.

Personally I think it would be much cooler to use quantum entangled particles. FTL communications, and completely secure. The only one that can read your message is the one that your sending it to.

yeah, but other people could mess it up so that no one could ever read it.

Wait, I thought quantum entanglement didn't allow for FTL communication.

I think this is different from quantum entanglement.

it doesn't.
but it does allow for unbreakable encryption.

Nono, I get that, but I was refering to Maerin's comment.

I get anxious when someone tries to violate relativity.

well the way i understood it (please correct me if i'm wrong) that when you alter the state of a quantum entangled particle the other particle changes at the same instant no matter the distance between them, although the only place that i have ever head of the experiments being done was on earth so no real distance to measure the speed of the interaction even if it was on the other side of the planet.

But isn't it only quantum information that gets to be transmitted between entangled particles, which isn't really usable for regular communication, and which cannot be "set" by anyone anyway? BTW, I'm really asking. I'd like to know how this stuff works - I'm also wondering about similar stuff in this thread. (Oops, there comes the scavenger hunt again! :P)

Also, just in case there's a way to use quantum entanglement for communication - is there a way to keep entangled particles stable and in one place for prolonged periods (like years)? What about in a container that can be moved? It would be necessary for any sort of practical application. That seems tricky but theoretically possible to me, don't know about keeping the QE link stable though.
Did I do, O CROM, did I as I said I’d do? Good! I did.

I love you geeks *grins* oh and sorry about me dropping off the planet for most of this week, i'm in cancun. anyway, the experiment that i was thinking of was done between (i think) MIT and tokyo, they entangled a pair of particles and moved one to japan. then they started to mess with its state and recording the changes and time stamping them. over that distance the interaction was effectively instant. I would love to see if there was any more info on this kind of stuff.

They're gonna do it!  Finally!

Quote from: Gizmodo
Fermilab outside Chicago will soon begin its Deep Underground Neutrino Experiment (DUNE), and what it hopes to accomplish is as brilliant and confusing as the book of its namesake.

The experiment starts with accelerating protons close to the speed of light. That beam of super-fast particles is measured and then shot out through 800 miles of rock, where it will pop back up in South Dakota to be measured at the Sanford Underground Research Facility, home of the largest neutrino detectors on Earth.

All the data gathered by both facilities will be analyzed by a team of 800 scientists across 150 institutions. Hopefully some conclusions can be reached about not just the elusive nature of neutrinos, but about how stars function and even why matter exists. Regardless, the experiment itself sounds cool as hell.
