http://www.kurzweilai.net/teleporting-information-achieved-by-tu-delft \nTeleporting people through space, as in Star Trek, is impossible by the laws of physics, but researchers at TU Delft‘s Kavli Institute of Nanoscience have succeeded in teleporting information. \nUsing quantum entanglement, they transferred the information contained in a quantum bit in a diamond to a quantum bit in another diamond three meters away, without the information having traveled through the intervening space. The results were published in Science May 29. \nHanson's research group produces qubits using electrons in diamonds. “We use diamonds because ‘mini prisons' for electrons are formed in this material whenever a nitrogen atom ["nitrogen vacancy center"] is located in the position of one of the carbon atoms. The fact that we're able to view these miniature prisons individually makes it possible for us to study and verify an individual electron and even a single atomic nucleus. \n“We're able to set the spin (rotational direction) of these particles in a predetermined state, verify this spin, and subsequently read out the data. We do all this in a material that can be used to make chips out of. This is important as many believe that only chip-based systems can be scaled up to a practical technology.†\nQuantum internet \nThe researchers say this development is an important step towards a network for communication between future ultra-fast quantum computers - a “quantum internet†that will enable secure information transfer. \n“The distance in our tests was three meters, but in theory the particles could be on either side of the universe,†said the head of the research project, Prof. Ronald Hanson. “The unique thing about our method is that the teleportation is guaranteed to work 100%. The information will always reach its destination, so to speak. And, moreover, the method also has the potential of being 100% accurate.†Hanson is planning to repeat the experiment this summer over a distance of 1300 meters, with diamonds located in various buildings on TU Delft's campus. This experiment could be the first that meets the criteria of the “loophole-free Bell test,†and could provide the ultimate evidence to disprove Einstein's rejection of entanglement. Various other research groups are currently striving to be the first to realize a loophole-free Bell test, which is considered to be the Holy Grail in quantum mechanics.
If we can teleport informationthen we cab teleport humans. Humans and everything else, is essentiallu information.
yup But then the door.opens to lots of dilemmas and paradoxes Sent from my LG-E739 using Grasscity Forum mobile app
God knows how far in the future all of that lies. Humans are like information that propogate further information and it can't be predicted what information will result. It might be pretty complex to teleport a human.
What do you mean? I'm not saying we can teleport humans right now. Only that humans themselves are information that can potentially be teleported just like any other information. That is, if we can teleport information.
Humans are a representation of information technically, just as a video game character is a representation of the code. The information can be teleported, but then must be translated and put back in order. so the human would still be broken down and rebuilt, not really teleported Sent from my LG-E739 using Grasscity Forum mobile app
They'd be no different really than the differences and experiences you go through moment to moment that change who you are. You're not the same person you were years ago, not the same person you were months ago, not the same person you were weeks ago, not the same person you were days ago, not the same person you were hours ago, not even the same person you were a second ago.. but you're still you.
That's very true. There's no aspect of ourselves that remains unchanged throughout our lives. "You" is the product of various aggregates. They change constantly, yet for some reason the "you" remains.
Sorry, but no. Collapsing a wave function, which in turn forces the wave function of the other entangled particle into a known and well defined state, is not the same thing as transmitting matter.
But theoretically couldn't you arrange the paired particles into the same state that the humans particles are in? Couldn't you copy the structure all the way down to the particles thus creating another you with your old self being disassembled from the collapsing wave function.

No, because humans are made up of fermions that are NOT in some entangled state. The fallacy in your reasoning lies with your reductionist approach. You can know the exact particle configuration of a human and you can predict a few subatomic interactions with great accuracy, but that does not mean you can construct a macroscopic object based on an understanding of the principles governing particle physics. Example, we know at the microscopic level how consciousness works. That does not mean we can create a desired consciousness from simpler and well defined particle and quantum field interactions. "Emergentism" reigns supreme here.
Can anyone go into greater detail about how a quantum internet would actually work (in terms of infrastructure and network)?
