That is one crazy setup.

Researchers Succeed in Quantum Teleportation of Light Waves
In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new breakthrough is a major step toward building safe, effective quantum computers.
No felines were harmed in the making of this experiment, which actually studied wave packets of light that existed in a state of quantum superposition, meaning they existed in two different phases simultaneously. This phenomenon is described in Erwin Schrodinger’s quantum mechanics thought experiment, in which a cat is simultaneously dead and alive, depending on the state of a subatomic particle.
In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.
The team employed a mind-boggling set of quantum manipulation techniques to achieve this, including squeezing, photon subtraction, entanglement and dyne detection. The photo above depicts their device, nicknamed the Teleporter, in the lab of Akira Furusawa at the University of Tokyo.
The results pave the way for high-speed, high-fidelity transmission of information, according to Elanor Huntington, a professor at the University of New South Wales in Australia who was part of the study.
“If we can do this, we can do just about any form of communication needed for any quantum technology,” she said in a news release.
Instead of using ones and zeroes, quantum computers store data as qubits, which can represent one and zero simultaneously. This superposition enables the computers to solve multiple problems at once. The new, faster teleportation process means scientists can move blocks of this quantum information around within a computer or across a network, Huntington said.
Optics researcher Philippe Grangier at the Ins ut d’Optique in Palaiseau, France, said it was a major breakthrough.
“It shows that the controlled manipulation of quantum objects has progressed steadily and achieved objectives that seemed impossible just a few years ago,” he wrote in an editorial that accompanies the study.
That is one crazy setup.
Again, see the Terminator thread. It's happening as we speak.
One day humans will be beaming up, Scotty, but I'd hate to be the first/second generation transporters who trust in the technology. You know after prolonged use that is going to slightly distort your brain and make you crazy (or some ).
Plus I always find it extremely unsettling that you *must* technically die in order to be transported. Even if the technology replicated perfectly without destruction, we don't want 2 of anyone wandering around.
Wouldn't the fact that you're destroyed to begin with to be reconstructed again someplace else mean said reconstruction isn't you, but rather just a likeness of you? I mean, even if it was possible to reconstruct memories, personality, etc, wouldn't your original self just disappear? A clone of you isn't you, no matter how many memories of yours it thinks are its own.
Read about it a few days ago... cool stuff...
Here's a "Quantum Entanglement for Dummies" kind of article:

Sounds like a story.
I was also thinking this sounded more like the beginnings of a transporter.
Actually, the theory is not that you're destroyed to begin reconstruction, you're simply both alive and dead at the same time in two (or more) different places. When you actually go check (measure) ONE instance, then all the others instances also fall into one or the other state, wherever they might be.
Obviously, creating the entangled copies of yourself is a lot easier said than done...
At this stage, the usage is not really human teleportation though, but transfer of light data through teleportation.
very true. energy is not the same thing as mass.
Exactly. As much as it might be you down to the last hair, would it ever really be you?
Also, if we can so easily replicate a person, whos to say we couldn't replicate many people from a single person, given the time and technology? Cloning without the need for anything other than raw materials and a transporter?
It's all very inaccurate speculation at this point, but as much as I love the concept, it horrifies me to think about actually doing it myself.
makes sense if we mining in the solar system and transportation is faster
Gentlemen, while cool to think about Star Trek transporters, this discovery only applies (for now) to a very unique form of energy; a photon.
Light/photons are one the greatest mysteries of the universe and, IMO, the secret to everything we call reality. Proving that photons can carry information in a dual-state is momentous, but fledgling.
The amount of information that can be transferred in this way in an applicable sense would revolutionize communications. Youre talking about 1080p video, real-time audio, zero delay interaction with the robot you sent to Pluto.
The very first radio signal that SETI sent out in the 70s, that very first signal some 40 years ago, could be re-broadcasted to the farthest reaches of known space in less than one year, in all directions.
Think of the world you were born to, Im 30, I remember the advent of cable television and a world without the internet.
If this experiment truly is the first step in quantum computing, in that light will be the first medium upon which information is sent and stored (with others to follow), that will be single greatest revolution of my time on this planet.
The first applicable quantum component available to the consumer market will change your life forever, much in the same way the internet has only x1000.
Take every computer in the world, put all their horsepower together and add it up. You'll have something like that on your bluetooth earset, its like comparing your current desktop to an abacus...moreso actually.
Im not a computer scientist, Im not a physicist, Im barely literate in either field. But if we live to see quantum computing become reality, applicable reality, not theory-world bull like wormholes, this world will never be the same and no one can predict what that world will be.
This is the Holy Grail of the Information Age. There was the Stone Age, the Bronze Age, the Age of Sail, Industrial Age and the Information Age will end almost overnight with a quantum computer. The Next Age will be something else entirely and I have as much chance of predicting what that is and will be as people in the bronze Age had of predicting life in the Information Age.
Heady stuff, indeed.
Good post DR.
to give another idea of how powerfull a quantum computer could be, if one was used as a brute force password cracker.... everything that is on the internet, and is behind some type of security, would no longer be safe. a password that could take a conventional super-computer years to crack would be done in seconds.
Technically, there's no way to know for sure whether it was "instantly" resurrected, because information can not be transmitted FTL. That rule helps keep causality (somewhat) in place.In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.
Hence the reason for the development of quantum cryptology...
Ah, here we get to a fun question.
Why wouldn't it be you?
What makes "you", after all? Is it the physical makeup? After all, humans replace cells constantly, to the point where there's a whole new "you" after 8 years or so (IIRC).
Having your memories and personality WOULD make it 'you', in a very real sense. Especially if there was no original 'you' left.
blasphemer!!!!!
Thats obviously true, I was just pointing out whats possible if a quantum computer where to be unleashed against the encryption used today.
The problem of using quantum tech to crypto attack a large enough modulo though, is that the current limit of entangled qubits is about 12 (fairly recent, the previous limit was 7 IIRC). Shor's quantum factoring algorithm requires at least as many qubits as Q-1, something we're somewhat far from getting to.
Didn't this happen like 10 years ago or something? I remember reading about it. It was called black science or something like that. Basically splitting a pair and whatever was done to one happened to the other regardless of the distance.
Thats different.... In this instance, they are both the same but in different states of reality. Hence the reference to Schrödinger's cat.... it was both dead and alive at the same time... so to speak.

Is light energy or matter?
Both, AFAIK.
http://en.wikipedia.org/wiki/Photon
It's a masslass form of matter that is also a form of energy.
