teleportation
teleportation in physics, the transfer of key properties from one particle (or group of particles) to another a significant distance apart without a physical connection between the two particles (or groups); also known as quantum teleportation. The two particles involved in the transference are said to be "entangled," that is, the properties of these particles are tied together even when they are far apart. It has been shown that a pair of entangled particles, which were once in contact but later moved too far apart to interact directly, can exhibit individually random behavior that is too strongly correlated to be explained by classical statistics. This phenomenon, called Einstein-Podolsky-Rosen (EPR) correlation or entanglement, was postulated by Albert Einstein , Boris Podolsky, and Nathan Rosen in 1935. Physicists once believed teleportation was impossible because it was thought to violate the uncertainty principle of quantum mechanics. However, teleportation has been demonstrated experimentally in a variety of systems, such as photons and coherent light fields. Because teleportation always destroys the particle whose properties are transferred, it is impossible to produce multiple copies of it in this manner. |

teleportation
teleportation in science fiction, the process of instantaneously transporting a person or an object between two points, usually by disappearing from one place and reappearing at a second place as a perfect copy by means that resemble or use radio signal tranmission and reception. The "science" that makes this possible is usually glossed over, but it is generally implied that the teleporting system functions as a large, three-dimensional facsimile (or fax) machine that scans, transmits, and reassembles the person or object being sent. Unlike the fax analogy, the original is almost always destroyed during transmission. In those stories in which the original is preserved, the plot becomes difficult to manage when the original and its replica meet. In 1993 an international group of six scientists confirmed that teleportation is possible in principle, but only if the original is destroyed. |
