Scientists achieve reliable quantum teleportation for first time
C/NET ^ | 05/29/2014 | Nick Statt

Posted on 05/29/2014 5:34:05 PM PDT by SeekAndFind

Albert Einstein once told a friend that quantum mechanics doesn't hold water in his scientific world view because "physics should represent a reality in time and space, free from spooky actions at a distance." That spooky action at a distance is entanglement, a quantum phenomenon in which two particles, separated by any amount of distance, can instantaneously affect one another as if part of a unified system.

Now, scientists have successfully hijacked that quantum weirdness -- doing so reliably for the first time -- to produce what many sci-fi fans have long dreamt up: teleportation. No, not beaming humans aboard the USS Enterprise, but the teleportation of data.

Physicists at the Kavli Institute of Nanoscience, part of the Delft University of Technology in the Netherlands, report that they sent quantum data concerning the spin state of an electron to another electron about 10 feet away. The results can be replicated accurately 100 percent of the time, the team said.

Thanks to the strange properties of entanglement, this allows for that data -- only quantum data, not classical information like messages or even simple bits -- to be teleported seemingly faster than the speed of light. The news was reported first by The New York Times on Thursday, following the publication of a paper in the journal Science.

Proving Einstein wrong about the purview and completeness of quantum mechanics is not just an academic boasting contest. Proving the existence of entanglement and teleportation -- and getting experiments to work efficiently, in larger systems and at greater distances -- holds the key to translating quantum mechanics to practical applications, like quantum computing. For instance, quantum computers could utilize that speed to unlock a whole new generation of unprecedented computing power.

Quantum teleportation is not teleportation in the sense one might think. It involves achieving a certain set of parameters that then allow properties of one quantum system to get tangled up with another so that observations are reflected simultaneously, thereby "teleporting" the information from one place to another.

To do this, researchers at Delft first had to create qubits out of classical bits, in this case electrons trapped in diamonds at extremely low temperatures that allow their quantum properties, like spin, to be observed.

A qubit is a unit of quantum data that can hold multiple values simultaneously thanks to an equally integral quantum phenomenon called superposition, a term fans of the field will accurately associate with Heisenberg's uncertainty principal that says something exists in all possible states until it is observed. It's the same way quantum computing may one day surpass the speeds of classical computing by allowing calculations to spread bit values between 0, 1 or any probabilistic value between the two numbers -- in other words, a superposition of both figures.

With quibits separated by a distance of three meters, the researchers were able to observe and record the spin of one electron and see that reflected in the other qubit instantly. It's an admittedly wonky conception of data teleportation that requires a little head scratching before it begins to clear up.

Still, its effects could be far reaching. The researchers are attempting to increase that distance to more than a kilometer, which would be ample leeway to test whether or not entanglement was a consistent phenomenon and that the information was traveling faster than the speed of light. Such experiments would more definitively knock down Einstein's disqualification of entanglement due to its violation of classical mechanics.

"There is a big race going on between five or six groups to prove Einstein wrong," Ronald Hanson, a physicist leading the research at Delft, told The New York Times. "There is one very big fish."

From Dictionary.com:

teleport: verb: to transport (a body) by telekinesis.

Transporting data is not the same, particularly because they apparently replicated the data (without actually physically moving it).

Very nearly everything in this article is wrong. No "data" is transmitted. No "information" is transmitted. Quantum computing does not depend on teleportation, per se. The experiment is not new. Bell's Theorem experiments have been going on for a very long time, and the current experiment is simply a slight improvement in ruling out something called the "locality loophole." Not revolutionary. Not earth-shattering.

Transporting state information for a quantum system is the same thing as physically moving the system.

It's unlike a classical system, in which the particles are distinguishable, and "particle A" on one side of a room is a distinct entity from "particle B" on the other side of the room. If two particles are truly quantum entangled, there is no "particle A" and no "particle B" because there is no way to know which is which: There is just a two particle system with the interchangeable entities separated in space(-time.)

Given that, a quantum system constructed remotely from its information (state vector or wave function) is NOT a copy. It is the original system.

Frank Tipler has an interesting religious and metaphysical discussion of this in his book The Physics of Immortality in which he discusses the fact that physical resurrection is a real possibility, because all God needs to know is your state vector in order to construct you. Since every electron in the universe is the same as every other [and indeed every quantum particle in the universe is the same as any other] it would still be the same "you" no matter what materials he used -- or where he chose to reassemble them; and it would be you... NOT a clone or identical twin.

Nothing is transmitted. That is the problem with articles like this: they're too sloppy with the physics because these are not intuitively accessible concepts.

This is a quantum system. It is meaningless to talk about an electron on "one side of the room" and an "electron on the other side of the room," because there is no such thing. There is a system composed of two electrons, which are not distinguishable from each other. The experimenters cannot do any experiment that verifies that the qubits they have on "one side of the room" are not the same qubits that they think are "on the other side of the room." [Or indeed -- what is more correct -- are actually both sets, on both sides of the room at the same time.]

The multi-particle state has a particular spin, which when affected by experiment must affect the entire system.

The article, like most of its kind, is a careless mixing of classical, relativistic, and quantum concepts. It's a conceptual mess.

The distance was three meters (or “about 10 feet”). This article is written for an American audience, which is why the standard feet distance is given.

Feet are no more or less natural than the meter in these experiments, and the experimenters and theorists don't use either of them. In natural units ħ = c = kB = 1, and the natural units of length are 1/(eV), which would make no sense to most lay people.

There is no communication, as there was no data sent from A to B. The article explains the experiment:

If you read this here qubit A, you may get 0 or 1. You don't know what it is because you never looked before. However if later you read the qubit B that is over there, you will get the same answer as at A.

As you can see, this does not transfer information, as you have no way to input it into the system. It's a set of two black boxes with the same content inside. You do not know what it is beforehand.

There is no FTL violation either - not any more than if you deal with two matchboxes that contain the same, unopened message. They "synchronize" instantly, but you still need to transport one of them from A to B - and even then it doesn't buy you much, as the message is a total surprise on both ends of the link.

Nope. Not true. If your state vector was transmitted and you were constructed from it, it would BE you, not a copy. This isn't Newton's Physics; it's quantum mechanics.

No, because of something called the No Communication Theorem. This is a quantum result which, very loosely, says HBO limits the distribution of Game of Thrones to no faster than that which can be transmitted by ravens...

You are dying and getting resurrected all the time due to quantum foam. "You" now and "you" 1 picosecond later are not the same. Of course, there are processes that act similarly on slower time scale. For example, most cells of your body die and get replaced, from once every few days to once in a year.

The "self" should be associated with consciousness. Or, as ancients used to call it, "soul." It persists even as hardware that runs it is changed, replaced or partially destroyed. These changes do not matter - not any more than a computer's OS depends on the exact USB port where you plug the mouse, or the brand of the mouse.

every electron in the universe is the same as every other [and indeed every quantum particle in the universe is the same as any other]

Looking at it another way, I think every individual electron exists on it's own, just as humans and planets exist on their own.

From Edward Frenkel, we have "... there are two kinds of elementary particles; fermions and bosons. The former are the building blocks of matter (electrons, quarks, etc), and the latter are the particles that carry forces (such as photons). The elusive Higgs particle, discovered recently at the Large Hadron Collider under Geneva, is also a bison."

I'm not a fan of still-used-in-USA medieval English measuring units. So it's “interesting” to see "feet" showing up in an article concerning cutting-edge scientific discovery.

In English speaking countries where the metric system has been imposed by government fiat, real people still use those medieval measurements. For instance, the clearance for vehicles at the Edmonton mall parking lot is described in feet. Cookbooks almost NEVER use Celsius. And even the food measurements that are described in metric by law don't use the supposed strengths of the system. For instance, in Canada, fish is sold by the 100 gram. One-hundred gram? Doesn't anyone use centigram? No, they don't. So, they made this fictitious measurement because for buying fish a kilogram is too much, a gram is way to little, and if you held a gun to a Canadian or Aussie or British head and ask what a decagram is, you have five seconds, the gun would go off 90% of the time.

I am not suggesting that grains should be used instead of milligrams. I am suggesting that in an article about the real-life effects of cutting edge science, it is not bad to speak in the language of the people addressed. And yes, the readers know 10 feet as well as they know three meters. In Egland, they certain know 10 stone better than 65 kilos or whatever it would be. It will be a long time before joules replace calories on the Kellogg's cereal box.

There is no problem with using nautical miles, imperial gallons and pints, the American versions of same, or pounds and feet for baseline measurements. Heck, we live in a time when computers can make near instantaneous conversions for those who can't pick up two or three systems as needed.

It doesn't, though. In a Uranium atom, for example, there are 92 electrons, but there really are not 92 individual electrons at all. In fact, there is NO individual electron in that system. There is simply a system composed of 92 electrons but no single identifiable negative charge entity exists...

The theory I like is that time and distance doesn't exists for entangled photons in their reference frame, though miles or even billions of miles apart in our reference frame, they are still in contact in their reference frame.

Sorry, but the reason I gave the definition for teleport is that the word does not mean replicate, observe, etc. It means to transport (a body).

The “teleportation” they are talking about here is not the deconstruction of a body and reconstruction of another. It is an observation on the entanglement of data associated with two separate bodies. I see nothing in the article to disabuse the notion that this was a replication (or observation of entanglement, if you prefer), rather than the actual deconstruction/reconstruction of the original body.

Words mean things - and I do not think that word means what they think it means.

I find that hard to believe.

Electricity is defined as being a pressurized flow of electrons. AC is back and forth and DC is a single direction flow.

Meanwhile, Edward Frenkel uses an analogy to explain "quantum field theory."

Frenkel writes in his book "Love and Math,: ... "... think of quantum field theory as a culinary recipe. Then the ingredients of the dish we are making are the analogues of particles, and the way we mix them together is like the interaction between the particles."

Your definition of teleportation is the same as theirs (and mine) your problem is that you are not understanding the physics of quantum particles.

A quantum particle is defined by nothing except for its wave function. If the wave function of a particle is transmitted, the particle is transmitted. It's not a copy. It's not a clone. It's the actual particle. In order to teleport the particle, all you need to send is the state information. That's all.
