A step towards quantum computing: Success at complete quantum teleportation - Polidicks

[video=youtube;f5vOfr1dl4o]http://www.youtube.com/watch?v=f5vOfr1dl4o[/video] [QUOTE]Furusawa group at the University of Tokyo has succeeded in demonstrating complete quantum teleportation of photonic quantum bits by a hybrid technique for the first time worldwide. In 1997, quantum teleportation of photonic quantum bits was achieved by a research team at Innsbruck University in Austria. However, such quantum teleportation couldn't be used for information processing, because measurement was required after transport, and the transport efficiency was low. So, quantum teleportation was still a long way from practical use in quantum communication and quantum computing. The demonstration of quantum teleportation of photonic quantum bits by Furusawa group shows that transport efficiency can be over 100 times higher than before. Also, because no measurement is needed after transport, this result constitutes a major advance toward quantum information processing technology.[/QUOTE] [URL]http://www.diginfo.tv/v/13-0068-f-en.php[/URL] warning: technobabble

All I was able to read was Quantum photonic quantum teleportion and quantum photonic teleportation. Holy shat there's a lotta quantums in that articles

That's some mad gear in that lab

Could some brainy know-it-all help translate this sciency mumbo jumbo into idiot level English for me?

[QUOTE=Simski;42153560]Could some brainy know-it-all help translate this sciency mumbo jumbo into idiot level English for me?[/QUOTE] this good. it made thing poof into other place.

Quantum computing? Fuck quantum computing. Now we have "complete quantum teleportation." I want to be completely quantumly teleported ASAP.

[QUOTE=Simski;42153560]Could some brainy know-it-all help translate this sciency mumbo jumbo into idiot level English for me?[/QUOTE] It's not actually teleportation in the colloquial sense. Basically if you have two particles it's possible to take the state (spin, velocity, etc), and transfer it to another particle across a distance, while destroying the initial case. The information is thus transferred across space at the speed of light. It's not moving particles, it's moving information.

Oh shit nevermind

[QUOTE=SGTNAPALM;42153792]you already do silly[/QUOTE] Now he can [I]get[/I] porn at the speed of light.

does this mean I can download linux distros faster?????

When they were talking about optics chips, I immediately thought of photocouplers.

Could you have a bunch of atoms of the same amount in two different locations and then send the information from the one group to the other. I can understand rearranging the atoms into the original form would be a problem.

[QUOTE=Lurklet;42153978]does this mean I can download linux distros faster?????[/QUOTE] if you have equipment like this lab I'm sure you'd have the spare change could buy all of the distros you need without worrying about pesky viruses quantum destroying said equipment

Associative relevance: [url=http://xkcd.com/1240/][img]http://imgs.xkcd.com/comics/quantum_mechanics.png[/img][/url] (Original scroll over: "You can also just ignore any science assertion where 'quantum mechanics' is the most complicated phrase in it.")

Another interesting thing about this method of communciation is the prevention/resistance to peeking the information (Spying). Normally if anyone viewed the information before it arrived, it will have changed quantum states somehow, thus signifying an interruption in the stream

I don't understand any of it. Will this allow instant communication? Or will the information get destroyed if you observed it anyway? Or am I thinking of something completely wrong and this is just a way to basically link qbits?

I still have nightmares about that cat.

So what you're saying is if we quantum teleport something small, let's say a pebble, then the pebble will essentially get annihilated into atoms but the stuff that made up the pebble (like spin, velocity, texture, yada, yada, fucking yada) will get transferred somewhere else? If so, that's amazing.

[QUOTE=teh pirate;42153697]Oh shit nevermind[/QUOTE] if you are destroyed but an exact, down to the spin on an electron in a chlorine atom in your digestive tract, copy of you was created, are you alive

[QUOTE=MaikkiBoi;42154722]I still have nightmares about that cat.[/QUOTE] What cat?

[QUOTE=zombays;42154993]That's even cooler.

You can't quantum teleport a pebble any more than you can make a lightbulb radiate a pebble. And that 'stuff' is not the particle itself, it's the observed aspects of the particle that collapse according to the uncertainty principle. Make no mistake, quantum teleportation is cool stuff, but science media has blown it way out of proportion. It has much more potential as a communications method that self-destructs if intercepted than as a wannabe Star Trek teleporter.

And how does one destroy a quantum particle? Or by destroy does it mean negate the features that render it a piece of a message (i.e. spin)

[QUOTE=Simski;42153560]Could some brainy know-it-all help translate this sciency mumbo jumbo into idiot level English for me?[/QUOTE] We need a teleporter riiiight here. Teleporter going up! Much obliged! -Except in real life.

Am I correct in thinking that this still requires regular communication? Or is this something different than what the Wikipedia article describes.

[QUOTE=Alec W;42156030]So we'd be using quantum particles as building blocks for code/messages, and then transferring them through quantum teleportation, and reading the result?[/QUOTE] Basically, yeah. Entangle two particles, separate them, and then use quantum teleportation to transmit data encoded through the particle's physical properties. [QUOTE=Alec W;42156030]And how does one destroy a quantum particle? [/QUOTE] Keep in mind a 'quantum particle' is a categorization, not a discrete thing. Any subatomic particle can be considered a quantum particle because it is subject to quantum mechanics, for example electron spin. [QUOTE=Alec W;42156030]Or by destroy does it mean negate the features that render it a piece of a message (i.e. spin)[/QUOTE] You got it. The [url=http://en.wikipedia.org/wiki/Uncertainty_principle]uncertainty principle[/url] basically guarantees that in order to send the 'message', you have to destroy the characteristics you're sending in the first place.

look at that fucking crazy-ass lab table jesus christ what does it all even do
