arstechnica.com— Scientists have recently had success teleporting information between photons over a free space distance of nearly ten miles, an unprecedented length.

Other than communicating between major data traffic nodes(such as level 3) I don't see how this would be practical in everyday existence. It would work for say dedicated two way radios but not for cell phones. I assume entanglement has to occur before the particles are sent to their respective locations. 'course, now that I think about, all's you'd need is a cellular network where when you make a call it sends a signal to the carrier which sends another signal to the recipient which polarizes the quantum bits in that phone to match yours and then you're taken off the cellular network........maybe?
I am not sure if this makes sense, but...maybe that is why we have so much trouble detecting gravity waves. Could it be that they propagate through one or more of the other dimensions string theory proposes? That would allow us to move information at the speed of light through these "tiny" dimensions, while the data appears to move instantly across a vast distance in the 3 dimensions of regular space-time -- giving the illusion that we have broken a law of nature?
If you take the axioms of QM to be true, then bell's theorem proves that QM and local hidden variable theories cannot describe the same universe. And that's in the strictest sense. Now it doesn't disprove local hidden variable theories, but a mountain of experiment would be my evidence that nature sides on QM's side...
No, you can't. You can create an effect that propagates faster than the speed of light, but it cannot be used to send information. This is critical. Without communicating about the inital state of the particle you cannot tell the difference between a random flip and a "teleported" flip. That information had to be sent in a normal, sub-luminal fasion.
@dooganNo, a law is not a theory. Laws are generally just a description of observed behavior.Laws describe. Theories explain. A theory can use laws as the basis to form a hypothesis and make predictions.Ever wonder why we had laws of gravity centuries ago, but still don't have a complete theory of gravity?Also, a theorem only applies to mathematics, where a closed proof is possible. No such entity exists in physics, because physical theories are based on empiral evidence rather than strictly mathematical deduction.
I get quite bewildered that not having studied I can only roughly follow the subjects I love, but I get the point, but not the specifics, I would love to know what a photon is, an individual light cell??? All this makes me marvellous technological advances available including in the field of defence, some of them not very desirable in inappropriate hands, my father told me had heard on Kol Israel, the Israeli radio station that there has been developed a formidable ray (laser, or something much more advanced) which can wipe out entire populations without destroying buildings, 4th Reich material I presume, the trouble is that once such ideas exist they will sooner or later be used, let?s trust in Justice or the Divine I guess. And then I wonder, for how long will all this technology last, perhaps till lack of energy or disasters destroy much and then all internet compiled or transferred knowledge will be more perishable than the clay tablets of old some of which were so tragically destroyed during the period of poor control over the city of Baghdad in Iraq following the American-led overthrow of Saddam Hussein, or by the Arab autonomouis administration in Israel around the Temple Mount out of barbaric spite.

Spooky action at a distance.

i say don't mess with the photons!
