My first test (if it ever gets this complex) would be to send a hot plate of food into next month and eat it when I arrive there.

[FeaRpb]

I remember back in 06 07 when they OCed a computer using liquid helium to process qubits. It amazed me, I am glad they are getting father with it now.

[FeaRpb]

If I remember right the article said, "Logically it processes so fast that it could predict the future." Or something like that.

Can anyone explain in something resembling english... How?

Ask Prot from K-PAX, he knows the answers!

Using quantum entanglement they allow two particles become entangled with each other and one particle mimics the other no matter how far the distance instantly. Which is teleportation; hence quantum teleportation. The real gold here is not teleporting hot dinner into the future but teleporting binary data, even qubits as quantum computing advances, extraordinary distances instantly. In short: infinitely fast internet with zero latency. Oh not to mention how much this will revolutionize unmanned space exploration

So far that is teleporting an effect. And that effect can be coded as data. It is not certain that the real particles teleported. But the behavior or relationship which was unique was teleported.

This could be much more profound though for computing. We currently use binary each bit is either on or off. Only two choices per bit of data. With a quantum entanglement a much higher order is possible. Many more than 2 choices per bit of data. That alone would improve performance drasticallly. The extra speed is just a bonus.

[Amphiron]

Yes it is not actually true so called "star trek" teleportation but it may evolve to that level in the future.

[AgentOblivious]

Technically they're not moving anything. They're not sending one particle somewhere instantly. they're entangling particles, so that you change one by affecting the other, right? So if you wanted to teleport yourself, you'd destroy yourself and make a new copy of yourself somewhere else, instantly, I think.

[FeaRpb]

I can't wait to see more progress. I am going to be keeping an eye on it.

[DocWalt]

I have a feeling we're going to talk about this in class tomorrow, haha. Thanks for the link, some good reading.

Yup, exactly.

[CoopKill]

Wait till the military gets their hands on this.

Has came along since I first read about it.

[TUFFTR]

So basically, porn will load instantly right? Sweeeeeeeeeetttttttttt

damn that was a scary movie when I was a kid.

LOL I saw that a few years back when channel surfing one day and got hooked. Funny as hell movie.

yes...but 80's geena davis in her skeevies. :yum:

If this scenerio be true (speaking on human teleportation), would we really be the same person. Or would the original die and a new life form be created? Would the escence of life be transfered? Would a continuous state of consciousness exist? Would this be considered suicide to the religous folk? Just some food for thought

[Goallie11]

Using this method that the article's about, I believe that the original would be destroyed and a new being would be created. It essentially kills you and makes an exact copy, so you would cease to exist, but other you would go on as if nothing happened.

I won't want to go through a teleporter until we can physically move every quantum bit, because I would cease to exist.

I've given this some though before when I first read about teleportation a while ago, and it's the conclusion I've come to.

[reallyxxxxxxloud]

So would we then if destroyed, then a exact copy replacing you is then made. Wouldn't that replica be new. Is this the answer to immortality? food for thought!!!

[Dbeltran24]

But would that new copy still be you? Yes your genetic code is the same, but is it you. Also, would it preserve the spark of life? I understand all of one is transported, but what starts everything working again once you've been rebuilt? or would the end result be a lifeless exact copy?

[terrets]

Impressive..:Clap::Bow:

I love technology and the amazing advances we are making..

But it scares me. How many years until the computers start thinking for themselves and building themselves. Its only a matter of time, you cant deny it wont happen. Sorry to say but it is inevitable. Unless we or mother nature destroys ourselves first..

And dont say it wont happen because we wont let it, someone is bound to make a mistake..

:transform:

[BigTyla]

You guys are thinking far too deeply about this! This is not teleportation in the physical sense. It is merely teleportation of STATE.

Based on my current and albeit sparse understanding of the subject, it appears that classical bits are used to communicate the state of the quibit to the end user, and it is the end user's responsibility to flip the quibit to the desired state.

Here, the term "teleportation" is only used to describe the fact that the quantum states between the two users are EXACTLY the same. No energy or matter has been transferred. No magic is occuring.

[reallyxxxxxxloud]

BigTyla thanks for ruining the buz dude lol.

[BigTyla]

I'm here to keep it real. :p

[Amphiron]

Hes right. All they are doing is exploiting an effect they found. One quantum particle spins up, the other will spin down, no matter where it is in the universe. Which allows them to TELEPORT data! :P

[Goallie11]

He is right, but it'll lead to real teleportation eventually.

[stealthII]

I can see that this is really going to be useful for space travel. Imagine being outside our solar system and trying to send a message to Earth, ie Voyager. It would take hours to get here using RF. I would think if we could get this down, it would make exploration a much smoother experience.

[Goallie11]

Yeah that'll be a great use for it. Instant universe wide communication!

Not to be offensive, but this is I-Robot stuff that's perpetuated and will NEVER happen unless we allow it to, which is essentially what you learn in "Logic & Programming Design" type classes. It's possible, but a computer can't do anything unless you program it to.

But we will allow it to happen. Someone someday will build a computer that can process data faster and out think a human mind. Then they will program it to learn to see what will happen. It is in our nature to be curious. And that will happen and then that computer will cross that boundry.

By then we'll have multiple instances of self and be able to upgrade ourselves using horizontal integration (hopefully), so it shouldn't be an issue. Rule number 1 of computing; if its not attached somehow it can't affect it.

Rule number 1 of computing; if its not attached somehow it can't affect it.

With genetic algorithms, machines can produce effects that would humans cannot comprehend. This is one example where your Rule #1 fails... and it baffles the guy who wrote the algorithm to begin with. Incredible how a computer that self-programs uses it's logic circuits in a way that is completely unrecognizable to a human.

http://www.damninteresting.com/on-the-origin-of-circuits


Dr. Thompson peered inside his perfect offspring to gain insight into its methods, but what he found inside was baffling. The plucky chip was utilizing only thirty-seven of its one hundred logic gates, and most of them were arranged in a curious collection of feedback loops. Five individual logic cells were functionally disconnected from the rest– with no pathways that would allow them to influence the output– yet when the researcher disabled any one of them the chip lost its ability to discriminate the tones. Furthermore, the final program did not work reliably when it was loaded onto other FPGAs of the same type.

It seems that evolution had not merely selected the best code for the task, it had also advocated those programs which took advantage of the electromagnetic quirks of that specific microchip environment. The five separate logic cells were clearly crucial to the chip’s operation, but they were interacting with the main circuitry through some unorthodox method– most likely via the subtle magnetic fields that are created when electrons flow through circuitry, an effect known as magnetic flux. There was also evidence that the circuit was not relying solely on the transistors’ absolute ON and OFF positions like a typical chip; it was capitalizing upon analogue shades of gray along with the digital black and white.

^Thanks..

And with technology advancing the way it is, theres no telling what will happen. It really is inevitable :).

I have programming experience and a few classes dealing with design. I believe it to be entirely possible. Just think about the AI stuff we have been coming up with...

We dont fully understand the universe, elements, physics, and even electricity.. I believe that all the laws of physics are not set in stone. They are bendable and breakable. You cant say they arent because we dont actually know. We dont know about parallel universes and or everything on antimatter..

You really cant say we understand everything about computers and programming. It may not be possible to happen now, but its very possible in the future. What happens when we start mixing machine with organic life or start making it so our machines create and change dna sequences?

I mean we have cars fucking thinking for us. Fuck that! Granted I know its just sensors watching for an object within a certain distance, but still. I dont trust these inventions. Theres so many different places that there can be bugs. I mean we havent even created a perfect OS yet..

Please dont argue that its not possible for computers to think for themselves and code for themselves and eventually take over. Theres no point because your not changing my mind lol.

Think about how technological objects were taken from Star Trek. We based inventions of that show. And we still do it today, whats different if we are creating fully sustainable AI's.

It really is amazing how a chip was able to program itself with analog behavior, when we designed it to only work with 1's and 0's. it seems that we are the ones with elementary knowledge, and the chip "knows" itself better than we will ever be able to.
