LONDON (Reuters) - It is not quite the "Beam me up Scotty" teleportation of Star Trek, but teams of scientists said Wednesday they had made properties jump from one atom to another without using any physical link. Physicists in the United States and Austria for the first time have teleported "quantum states" between separate atoms. The breakthrough may not yet make it possible for people to disappear and reappear somewhere else, like actors in a science fiction television show. But it could help lead to "quantum computing" technology that would make superfast computers. Quantum states include physical properties such as energy, motion and magnetic field. "We've done it for the first time with massive particles, with atoms," Rainer Blatt, of the University of Innsbruck in Austria, told Reuters in a telephone interview. Two years ago scientists at the Australian National University announced they had teleported a laser beam of light from one spot to another in a split second. Blatt and his colleagues and another team of scientists at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, reported the first teleportation of atoms in two reports in the science journal Nature. The basic theory of quantum teleportation was outlined in 1993 by physicist Charles Bennett and his colleagues. Quantum computing requires manipulation of information contained in the quantum states of the atoms. "Using teleportation as we've reported could allow logic operations to be performed much more quickly," physicist David Wineland, the leader of the NIST team, explained in a statement. The research involved quantum entanglement -- in which the quantum states of two or more particles are linked without physical contact. "There are quite a few implications ... more on the scientific side," Blatt said. "We are far away from beamers, like beam me up Scotty," he added. http://story.news.yahoo.com/news?tm...u=/nm/20040616/sc_nm/science_teleportation_dc yaaaahhhhhhhhhhhhh I have quantum entanglement yaaahhhhhhhhhhhh
There's a story on teleportation in this month's issue of APC magazine... Haven't read it yet, but it sure would cut travel times.
There's a big difference between making two particles have the same spin and teleporting a human being somewhere. I think we should be more excited about the benefits for quantum super-computation research, or is excitement not possible unless science emulates star-trek?
We will *never* be able to teleport human beings or even small objects. Where this stuff does come in handy is in things like quantum cryptography. Sam
i also read this in The TImes last night at about 2;30AM ( so i guess thats this morning ) walking back from town ever so slightly pissed, and the only reason i was walking because i spent my bus money that i set aside on a kebab rofl. But yeh we're far away from teleportation, i doubt it could ever happen. Might hep with Quantum computing though So it cant be all too bad
i agree with acriminous, id rather more like to get excited over something which i will witness, rather than sdomeone i will not. But i disagree that teleportation of objects will never happen. Just as people 20 years ago may say teleportation of atoms is impossible, and of 100 years ago saying machines which add are impossible (speculation )!I dont feel it prudent to comment upon the may be impossible, however i would agree that its highly unlikely Unless we dont actually move as it is, and we teleport everywhere, everytime we move our hands, just a miniscule teleport. hmm. not usually. They always say loads of fancy stuff. Like this twisted photons. Im reading the article, it says "unimited amount of twists is possible". Im thinking, well then, matter could theoretically be decompiled by machine and the data could be transmitted to create a clone on the other end. Then it goes on to say a maximum of a few hundred would be possible as the light would distort. Totally gets my hopes up, and dash it all! But still, twisted light the future of broadband. Imagine fiber optics x 300. Fantastic!
And the other teleport question is 'is it actually you at the other end?' You are taken apart atom by atom, and the state and position of the atom is recorded and transmitted to the reciever. At the reciever, you are rematerialized using completely different atoms - so is it acctually you? Plus I seem to remember reading that the act of disasembly would release so much energy it would vaporise the transmitting station... and probably the surrounding area for some distance.
No, not even that, they've teleported the state of an atom, ie it's direction of spin, energy level, etc Yeah that is one of the interesting points. If they got all the atomic data about you they needed without disassembly then it would be possible to create an exact copy of you, leaving 2 of you, they would then have to destroy the first one. If there are two you's how could you perceive the same consciousness through both, or would you simply have a twin brother with a new consciousness and it wouldn't be you in a consciousness sense at all. I guess I'd be happy to teleport object around, being able to "fax" the product you just order on the internet instantly to your home would be great, in fact if they didn't destroy the original copy then they'd make quite a lot of money. As for teleporting myself though, no ta'.
yeah, im not saying its gonna happen straight away. 6.02x10^23 per mol is alot of atoms to do, i grant, but you never know what scientific breakthroughs come in the future. Maybe its just me, but saying something is impossible just seems like quitting before youve even tryed. Its a good job there are always people who do believe otherwise some of the stuff we have today may not be here!
I personally think that there is no reason not to do research in the field. Yes, teleporting a human being might seem a bit ambitious now, but who knows what useful information could be obtained from experiments carried out in teleportation research? It's 'out there' research like this that brings us the most remarkably useful discoveries.
I know. I was trying to keep it simple for people that haven't studied physics to anything past A-level. Yes, but this research is far more valuble in terms of quantum cryptography and computing than it will be in moving objects about. To be fair, a lot of confusion is caused by the use of the word "teleportation". They aren't really "teleporting" anything- they are producing a copy of it, which is entirely different. Sam
Don't become a part of the wrong quote club. Pickup some books on Leonardo da Vinci and tell me it will *never* happen. QUOTES: No one will need more than 637Kb of memory for a personal computer - Bill Gates 1981 Everything that can be invented has been invented - Charles H. Duell, Office of Patents, 1899 There is not the slightest indication that nuclear energy will ever be obtainable. It would mean that the atom would have to be shattered at will. - Albert Einstein, 1932 It will be years--not in my time--before a woman will become Prime Minister - Margaret Thatcher, 1974 We don't like their sound. Groups of guitars are on the way out - Decca executive, 1962, after turning down the Beatles There is no reason anyone would want a computer in their home. - Ken Olson, president of Digital Equipment Corp. 1977 Who wants to hear actors talk? - H.M. Warner, Warner Brothers, 1927. I think there's a world market for about five computers. Thomas J. Watson, chairman of the board of IBM. Radio has no future. Heavier-than-air flying machines are impossible. X-rays will prove to be a hoax. - William Thomson, Lord Kelvin English scientist, 1899 While theoretically and technically television may be feasible, commercially and financially it is an impossibility. - Lee DeForest, inventor “Louis Pasteur’s theory of germs is ridiculous fiction.” – Pierre Pachet, Professor of Physiology at Toulouse, 1872
Well thats all good and well, but then you're missing out all the thousands if not millions of times that the naysayers are correct- for instance, people said that faster than light travel was impossible. Then einstein *proved* it was impossible... Teleportation of humans will *never* happen, and even if it does it will be an entirely different method to that that they've used here. Sam
einstein may only have proved you cant get somewhere faster than light conventionally, when you get into it there are several ways it could be theoretically achieved. whatever the current theory on teleportation is may be impossible to teleport a human, but whose to say other theorys wont come along which does make teleportation entirely possible!
This is all well and good, but it is not teleportation. People have mentioned it here in this thread, and Im probably repeating them... this 'teleportation' is only the cloning of atoms. Admitadly, it does go as far as making the possibility of a star-trek "replicator" type device whereby you can order whatever you like and it 'builds it' atom by atom, or rather, clones it from an existing object. Personally, I wont get excited until we can bend space using a technological device, then I'll get excited -- especially as it bodes well for space travel.
Um, Einstein's Theory of Relativity. Let's think about the words for a moment. He hasn't PROVEN anything. He 'proved' that with what we CURRENTLY know, his theory holds true. That's why it's called a Theory, and not a fact. Faster than light travel is not possible right now. Doesn't mean it won't be possible sometime in the future.
Our survey says "ERRRR-ERRRRRR". In science, what you are calling a theory is a "hypothesis". A Theory is something that is tried and tested, and works. It's Einstein's Relativity Theorem, not Einstein's Relativity Hypothesis. Sam
I don't think anything can move as fast as light. But who says we have to physically move through our space-time (in an inch-by-inch manner) to arrive at another destination? I have read that quantum mechanics allows things to disappear and reappear, albeit in close proximity, but they are still saying it happens. I think Stephen Hawking alludes to this dimentional warp. Like trying to get from one corner of a box to another corner...instead of going through the middle, we discover the box is twisted and warped and we don't have to travel what appears to us to be a straight line...but we can hop out of our dimension and travel in another then hope back in. Poof...we have disappeared and reappeared in a matter of a split second, across the box. Imagine what other breakthroughs can be made by allowing ourselves to discover, or otherwise use, these other dimensions (if they do exist).
