Baby Steps Toward Quantum Computers
Mz6 writes "In a step toward making ultra-powerful computers, scientists have transferred physical characteristics between atoms by using a phenomenon called entanglement, which Einstein derided as 'spooky action at a distance' before experiments showed it was real. Such 'quantum teleportation' of characteristics had been demonstrated before between beams of light. Teleportation between atoms could someday lie at the heart of powerful quantum computers, which are probably at least a decade away from development. Researchers using lab techniques can create a weird relationship between pairs of tiny particles. After that, the fate of one particle instantly affects the other; if one particle is made to take on a certain set of properties, the other immediately takes on identical or opposite properties, no matter how far away it is and without any apparent physical connection to the first particle." Reader starannihilator adds: "Physics Web provides a good graphic summary of the phenomenon, as well as a good technical article."
Be sure to invest in Skynet while the gittin's good.
Isn't this the correlation effect mentioned in the prime intellect story?
In the PI universe, a Beowulf cluster of these imagines YOU!
So we've got the one atom thing down now. The trick is getting a whole lot of atoms to do it at the same time. If we can convince the porn industry that it would be beneficial to them, We'll be teleporting around the world in less then 5 years. Maybe I should patent teleporting prostitutes.
It was just a dream, Bender. There's no such thing as two.
Scotty's busy trying to talk to the mouse.
"HELLO COMPUTER"
Alice, instantaneously transfers information about the quantum state of a particle to a receiver called Bob. The uncertainty principle means that Alice cannot know the exact state of her particle. However, another feature of quantum mechanics called "entanglement" means that she can teleport the state to Bob.
Alice: Bob, now that our qubits are entangled, I don't know if mine's spin up down.
Bob: How 'bout I observe yours for you. How about there?
Alice: Nope.
Bob: Here?
Alice: Closer to this side of the gaussian, Bobby.
Bob: How about here?
Alice: OOOOOHHH! You collapsed my wave function DeBroglie!
Bob: Your qubit is now spin up, in case you were wondering... who's DeBroglie?

That really is my homepage, no kidding.

Only government would want new technology this fast, maybe your NSA, that around codebreaking.
Only the government would want it? Hell, I'd want it! Who wouldn't?

Can you imagine playing Unreal Tournament at a ping of 0? and having a Inernetlink with and unlimited speed? [well depends on the put and get on the link ion] You could probably syncronize what ever you want in just a few s.

Find stars with earth-like planets, send probes containing quantum-entangled data comms gear and pretty well documented interfaces, and invite them to offworld their call centres to India.
Too bad I can't bloody understand any of it!
Having scientist using words like "spooky" and "weird" cannot be a good thing...
Ronald said nothing. He flung himself from the room, flung himself upon his horse, and rode madly off in all directions.
Rarely does such a great opportunity to karma whore occurr. If you can troll, then I can whore.

The Improbability Theorem states that all of the above statements can be expressed as "step 1" in the three step business plan. I'll leave the proof as an exercise for the reader.Am I the only one who read the headline and imagined this giant baby walking slowly toward a rack of computers?
So does this mean that all the future Windows Quanta PCs will go blue screen at the same time?
I'm kidding...well, sorta.
Just another day in Paradise
I can't wait for this.. Imagine, once scaled up, this will allow real Voodoo dolls to work! I can't wait to get one, and teleport jabs to my ex-wife.
"Do you have any idea how fast you were going?"
The particle replies,
"No, but I know exactly where I am!"
Ba-dah-bing!
modern choral music...
I didn't mean to imply otherwise. It is the most obvious and well-known way of causing states to collapse.
