It all comes down to moving information from point A to point B. These experiments are important in developing networks that can distribute quantum information at transmission rates far faster than today's most powerful computers. Given these advancements, you can see how quantum teleportation will affect the world of quantum computing far before it helps your morning commute time. Just two years later, European physicists were able to teleport quantum information through an ordinary optical fiber used for telecommunications. They teleported a photon 60.3 miles (97 kilometers), 50.3 miles (81 kilometers) farther than the previous record. In 2012, researchers at the University of Science and Technology of China made a new teleportation record. "One is the carrier of information and the other one is the storage medium". "It is one step further because for the first time it involves teleportation between light and matter, two different objects," explained team leader Dr. In 2002, researchers at the Australian National University successfully teleported a laser beam, and in 2006, a team at Denmark's Niels Bohr Institute teleported information stored in a laser beam into a cloud of atoms about 1.6 feet (half a meter) away.
Still, their progress is quite impressive. Since 1998, scientists haven't quite worked their way up to teleporting baboons, as teleporting living matter is infinitely tricky.
In other words, when Captain Kirk beams down to an alien planet, an analysis of his atomic structure passes through the transporter room to his desired location, where it builds a Kirk replica. However, photon A no longer exists as it did before the information was sent to photon C. When researchers apply the information from photon A to photon C, they create an exact replica of photon A. By entangling photons B and C, researchers can extract some information about photon A, and the remaining information would pass on to B by way of entanglement, and then on to photon C. If researchers tried to look too closely at photon A without entanglement, they'd bump it, and thereby change it.
As predicted, the original photon no longer existed once the replica appeared. The Caltech team read the atomic structure of a photon, sent this information across 3.28 feet (about 1 meter) of coaxial cable and created a replica of the photon on the other side. In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups, made IBM's teleportation theory a reality by successfully teleporting a photon - a particle of energy that carries light. The work continues today, as researchers combine elements of telecommunications, transportation and quantum physics in astounding ways. Since that time, experiments using photons have proven that quantum teleportation is, in fact, possible. 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. Why? The act of scanning disrupts the original such that the copy becomes the only surviving original. Physicist Charles Bennett and a team of IBM researchers confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed. That year, the concept moved from the realm of impossible fancy to theoretical reality. Global transportation will become instantaneous, and interplanetary travel will literally become one small step for man.ĭoubtful? Consider for a moment that teleportation hasn't been strictly sci-fi since 1993. It's called teleportation, and you probably know it best from the likes of " Star Trek" and "The Fly." If realized for humans, this amazing technology would make it possible to travel vast distances without physically crossing the space between.
Sure, it kind of amounts to chunking your kid in a subatomic wood chipper every morning, but just think of all the time you'll save!
