Is teleportation the key to overcoming the Uncertainty Principle?

AI Thread Summary
The discussion centers on a recent article about advancements in quantum teleportation, specifically the teleportation of information rather than physical matter. Participants express skepticism about the accuracy of the reporting, noting that the article may have oversimplified complex scientific concepts. Key points include the distinction between teleporting information and matter, with some participants questioning how the researchers addressed challenges related to wave function collapse and the Heisenberg uncertainty principle. The conversation highlights the nuances of quantum mechanics and critiques the clarity of language used in popular science reporting. Overall, the excitement about the potential of teleportation is tempered by concerns over the understanding and communication of the underlying science.

Wow! :bugeye:


What does everyone think about this one?
 
Physics news on Phys.org
Pretty cool, but ill be impressed when they can do an object, then it will really take off.

Not sure if this is accurate (and I think not, since it's been dumbed down extremely) but it says they teleported matter half a meter.

poor choice of language too, "thousands of billions of atoms" :-p

The reporter who wrote the article misunderstood what the scientist was saying. Read what the scientist was saying. The scientist does not say that matter itself was teleported.

Right but they still teleported information. How do they get around wave function collapse and Heisenberg uncertainty principle?

They finessed their way around all that. The article descibes how, in a nutshell.
 
At long last researchers have teleported the information stored in a beam of light into a cloud of atoms

Opening sentence, Is that a joke? Do they know the meaning of the words they use?

When i was at uni, that was called absorption...

(physics) the process in which incident radiated energy is retained without reflection or transmission on passing through a medium; "the absorption of photons by atoms or molecules"

I don't know if I am going to bother reading the rest...

I don't see anything concerning the Uncertainty principle. It says how they got around Wave function collapse just by being "carefull".

Thats all I see though.

From the Wikipedia:
http://en.wikipedia.org/wiki/Uncertainty_principle

"Prior to the publication of the EPR paper in 1935, a measurement was often visualized as a physical disturbance inflicted directly on the measured system, being sometimes illustrated as a thought experiment called Heisenberg's microscope. For instance, when measuring the position of an electron, one imagines shining a light on it, thus disturbing the electron and producing the quantum mechanical uncertainties in its position. Such explanations, which are still encountered in popular expositions of quantum mechanics, are debunked by the EPR paradox, which shows that a "measurement" can be performed on a particle without disturbing it directly, by performing a measurement on a distant entangled particle." From your article:

"Because measuring any quantum state destroys it, that information cannot simply be measured and copied. Researchers have long known that this obstacle can be finessed by a process called teleportation, but they had only demonstrated this method between light beams or between atoms.

"In taking the next step, Eugene Polzik and his colleagues at the Niels Bohr Institute in Copenhagen shined a strong laser beam onto a cloud of..." And so on.
