Из гpязи да в князи…


Из гpязи да в князи…

From rags to riches, from cash to bitches, the fun
They said we can't and it couldn't be done
If we don't get it with this rap shit, son
Then I'm a get them all and one-by-one…

Over five years ago, scientists succeeded in teleporting information. Now, researchers in Japan have used the same principles to prove that energy can be teleported in the same fashion as information. Rather than just hastening the dawn of quantum computing, this development could lead to practical, significant changes in energy distribution. According to the theory, developed by Masahiro Hotta of Tohoku University, Japan, a series of entangled particles could be stretched across an infinite amount of space. By inducing an energy change in one of the particles, the other entangled particles would change as well. Eventually, to preserve conservation of energy, the original particle would be destroyed, with its energy passing to the final particle in the chain. Thus, the energy has been teleported from one particle to another. Naturally, Hotta doesn't present any blueprint for replacing power lines with teleporting energy, concentrating instead on the implications for studying quantum mechanics. However, with a concept this profound, the implications beyond theory are nearly endless. Even serious scientists support these exciting prospects for its unusual idea of a lightning move from point A to point B. Thus, even the founder of cybernetics, Norbert Wiener in his work "Science and Society" dedicated to "the possibility of travel by telegraph" a chapter. Indeed, in several laboratories around the world carried out a successful quantum teleportation. Quantum Teleportation is because quantum objects - atoms - have such properties, which are caused by the laws of the quantum world and in the macrocosm, that is, in our usually not observed. These are the properties of particles and form the basis of experiments on teleportation. In addition, it is important to understand that quantum teleportation - a transfer is not an object, but an unknown quantum state of one object to another quantum object. Not only that the quantum state teleported object and remains a mystery to us, it also irreversibly destroyed. But what happens exactly - so is that in these experiments produced an identical state of another object in another location. The first experiment on quantum teleportation of a photon polarization state was held in 1997, a group of physicists led by Anton Zeilinger (University of Innsbruck) and Francesco De Martini (University of Rome). The experiments were continued in 2004, physicists M. Riebe and MDBarrett. In 2006, the research group of the Neils Bohr Institute in Copenhagen was first performed successful teleportation between objects of different nature - the laser photons and cesium atoms. January 23, 2009 for the first time scientists have teleported the quantum state of the ion by one meter. And now a new breakthrough - May 16, 2010 Physics of the Scientific and Technical University of China and Tsinghua University, conducted an experiment to transfer the quantum state of photons at 16 kilometers in free space. Earlier experiments with photons used fiber-optic communication lines of a few hundred meters. The experiment was designed by well-known scheme with three photons A, B and C. It sender and receiver are given C and B photons from entangled pairs, and the sender, who is also a particle A by taking measurements of AC, resulting in an initial state A had been destroyed. The measurement result is sent to the standard channel receiver, which then conducts the necessary transformation on the particle B and restores the original state A. The quantum channel is connected Badaling, located 75 km from Beijing, and Huaylay that in Hebei province. Pairs of entangled photons, one of which is sent to a distance of 16 km, the physics obtained by the method of spontaneous parametric scattering using a crystal of beta-borate of barium β-BaB2O4. Reportedly, some based on the experience of reliability index for the transfer of quantum state was equal to 89%. In the meantime, the practical application for quantum teleportation was found quickly - that quantum computers, where information is stored as a set of quantum states. Here quantum teleportation has been an ideal way to transfer data, which essentially eliminates the possibility of intercepting and copying information transmitted.
