Photon Experiments from http://www.howthingswork.com In 1993, the idea of teleportation moved out of the realm of science fiction and into the world of theoretical possibility. It was then that physicist Charles Bennett and a team of researchers at IBM confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed. This revelation, first announced by Bennett at an annual meeting of the American Physical Society in March 1993, was followed by a report on his findings in the March 29, 1993 issue of Physical Review Letters. Since that time, experiments using photons have proven that quantum teleportation is in fact possible. In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups, turned the IBM ideas into reality by successfully teleporting a photon, a particle of energy that carries light. The Caltech group was able to read the atomic structure of a photon, send this information across one meter (3.28 feet) of coaxial cable and create a replica of the photon. As predicted, the original photon no longer existed once the replica was made. In performing their experiment, the Caltech group was able to get around the Heisenberg Uncertainty Principle, the main barrier for teleportation of objects larger than a photon. This principle states that you cannot simultaneously know the location and the speed of a particle. But if you can't know the position of a particle, then how can you teleport it? In order to teleport a photon without violating the Heisenberg Principle, the Caltech physicists used a phenomenon known as entanglement. In entanglement, at least three photons are needed to achieve quantum teleportation: Photon A: The photon to be teleported. Photon B: The transporting photon. Photon C: The photon that is entangled with photon B. If researchers tried to look too closely at photon A without entanglement, they would bump it, and thereby change it. By entangling photons B and C, researchers can extract some information about photon A, and the remaining information would be passed on to B by way of entanglement, and then onto photon C. When researchers apply the information from photon A to photon C, they can create an exact replica of photon A. However, photon A no longer exists as it did before the information was sent to photon C. In other words, when Captain Kirk beams down to an alien planet, an analysis of his atomic structure is passed through the transporter room to his desired location, where a replica of Kirk is created and the original is destroyed. While the idea of creating replicas of objects and destroying the originals doesn't sound too inviting for humans, quantum teleportation does hold promise for quantum computing. These experiments with photons are important in developing networks that can distribute quantum information. Professor Samuel Braunstein, of the University of Wales, Bangor, called such a network a "quantum Internet." This technology may be used one day to build a quantum computer that has data transmission rates many times more advanced than today's most powerful computers. for more go to http://www.howthingswork.com/teleportation2.htm

I'm not questioning those Caltech's experiment, just the article's scientific accuracy. Any physists out there that can elaborate? __________________

I believe this is just a semantic error. Photons are composed of the same quanta that electrons, protons, and neutrons are composed of, I'm guessing. So while a photon doesn't have atomic structure, it does have quantum structure. The fact that quanta are mass-less shouldn't mean much anymore, since we've all heard by now the E=Mc2 (don't know my superscript codes). __________________

The fact that quanta are mass-less shouldn't mean much anymore, since we've all heard by now the E=Mc2 (don't know my superscript codes). | first off...NO! photons are not made of the same quanta that make up electrons, protons, and neutrons. In fact, even electrons aren't made of the same quanta as protons and neutrons. First off, Protons and Neutrons are made up of "up" and "down" quarks (an "up" has a charge of +2/3 and a down has a charge of -1/3), while leptons (electrons and neutrinos) are made of another quantized particle that I haven't studied yet, so maybe i'll tell you about these later, but back to photons... Photons aren't even really considered to be elements of mass or anything. Photons are just "energy carriers". They are the particles that carry electromagnetic force, and as such...are not made of quarks or whatever. And second off...if sciententists wanted to prove that teleportation was possible...why didn't they study electrons instead of photons? Electrons naturally travel in jumps from point A to point B without ever having occupied any of the area between A and B, so it would be natural to study electrons instead of photons...

Hmmm... Teleportation is very interesting. It might even be able to prove whether or a person has a soul, don't you think? Say, if a person has a soul, and if a soul is not a physical property, then it can't be teleported. What you get on the other side of the teleport device is a human vegetable. Any thoughts? __________________

Any thoughts? | If human teleportation worked and the person remained the same, then it would prove different...that mind and body are inseperable. Then the 'soul' would be physical chemistry inside the body. __________________

Any thoughts? | Hey not too different than watching tv fer 30 years seriously, tv's modus operendi is to present realities so fifth rate that the soul literally has to shut down within the first few minutes of bombardment with that said though, the soul is always around waiting to come back if the mind will make the free will choice to not subject itself to such utter tripe on a continual basis. U can shove that 'chemical' analysis of the human soul where the sun don't shine; it's about the vibe ;0) Mavi forum |
