Looking for quantum Einstein errors
Albert Einstein, no doubt, was a brilliant scientist; Alas, even a genius is not immune from mistakes. There is reason to believe that relatively recently, scientists at the University of Griffith found a new bug in the theories of Einstein. In the 20s and 30s of the scientist he admitted that does not support the theory of the influence of the measurement of the particle to its position - the so-called `` terrible long-range. Now a team of scientists from Japan and Australia was able to show that `eerie dalnodeystvie` really there - at least, when working with photons; Einstein proved thus in this situation is not quite right.
A key role in the proof of wrong Einstein played Professor Howard Wiseman of Griffith University; working together with scientists from the University of Tokyo, he was able to show and measure it, what Einstein did not believe. `Nonlocal collapse of the wave funktsii`, speaking the language of science, has long remained a theoretical concept. Quantum mechanics implies that any individual particle can be described by a wave function, spreading over large distances, but never observed in two places at once. Just last detail in the definition and caused at the time of Einstein`s skepticism - in the 1927th scientist made it clear he does not believe in what he called the `terrible dalnodeystviem`. Instantaneous collapse of the wave function of a particle upon observation looked, really, is not quite clear; its very existence could be explained by the general theory in which the universe appeared as a probability wave. According to this theory, every particle in the universe at the same time is in several places at once - and each place has to a certain probability. Classic experience provides an electron shot through a screen that done two holes-gaps. In conventional experiments, the particle will pass through both slits at once. On the other hand, if the process will be organized observation - for example, by aiming at the point of passage of the camera - the wave function collapse and expects the passage will only happen through one of the slits.
In Einstein`s view, this phenomenon exist could not; He, among other things, violated the guiding principle of relativity - the principle of the maximum speed of light as a transmission rate of any type of information. Now, however, the distrust of the great scientist most likely would have been dispelled - because for an Australian-Japanese team experience suggests quite unequivocal conclusions and interpretations. After 90 years after Albert Einstein he voiced his opinion, the theory of action at a distance terrible was able to prove in practice. To do this, the scientists needed one photon and two laboratories; Special homodyne detectors (instruments that measure wave properties) have shown that the collapse of the wave function - an effect very real and observable in reality. It should be noted that annoying Einstein protivorechieudalos eliminated in a few years; Further experiments showed that an interaction between two quantum particles even faster speed of light, but to transmit information is not suitable in principle.
Experiments of this kind were set before, but this kind of evidence the scientists could not get; if before the work was carried out with pairs of particles, experimentalists are now working with a single photon. The phenomenon itself is very, very strong evidence of the existence of quantum entanglement of individual particles. Scientists have long been interested in this particular kind of quantum entanglement; It is assumed that it can be used to establish a truly effective system of quantum communication and computation.
Professor Wiseman explains that Einstein did not take kogda-to orthodox quantum mechanics; the basis of his disagreement with this theoretical system was just arising in his mind the paradox of a single particle. That is why scientists were so important to show the non-local wave function collapse to a single particle; This, I must say, it was possible to them in full. Kogda-to Albert Einstein believed that the problem of finding a particle is much better explained by the fact that this particle is present at only one point; This would make it possible to abandon the idea of ??instant collapse of the wave function at all other points. Wiseman and his colleagues were able to put the experiment so as to refute the premise of the great predecessor; using special detectors helped them get some very interesting results. One group of researchers has received some data, while the other - with the help of quantum tomography - has been able to verify the effect of the decisions taken. Various solutions have led to a different wave function collapse - thus confirming the presence of this function itself and showing that Einstein in his skepticism was still wrong.
Of course, even now is still very, very early even to dream of full disclosure of the mysteries of quantum mechanics; this area, in spite of all made it advances, it is still very, very difficult. In the long term, however, the disclosure of the secrets of the quantum world promises incredible opportunities; so, in theory, quantum computers will be able to perform calculations at a rate on the order of the superior beings, and quantum forms of data transmission - opyat-taki in theory - its speed may well surpass all existing analogs. The works in this field are to continue; Scientists around the world continue to pull hard at their quantum secrets, learning them better and better. Certainly in the future will be refuted by many more major theories - as shown by experiments Wiseman, even genius levels of Albert Einstein is not infallible; Sooner or later, however, even in quantum physics are no secrets there will be for a man - such is the irrepressible nature of human curiosity, not giving people stop in front of the mysteries and riddles.
