Quantum entanglement-far beyond the speed of light "transmission", the world view has been refreshed

Quantum entanglement is a phenomenon in which particles interact with each other in a system of two or two particles, this effect is not limited by distance, even if two particles are separated in the Milky Way 100,000 light years at both ends of the galaxy, one particle changes will still affect the other particles in a moment ...

Microscopic particles, such as photons and electrons, or mesoscopic particle like molecules, Backmunsterfull, or even small diamonds, can observe quantum entanglement.

Quantum entanglement is a phenomenon that occurs purely in the quantum system and cannot be found in classical mechanics.

Assuming that a composite system consisting of two particles is entangled in a quantum entanglement, and that a measurement of one of the particles results (for example, spin is spinning), then another particle will be measured at any later time, and it is bound to get the associated result (in this case, spin to spin).

Quantum entanglement works faster than the speed of light. A recently completed experiment has shown that quantum entanglement acts at least 10,000 times faster than the speed of light. This is just the lower speed. According to quantum theory, the effect of measurement has instantaneous property.

In the 1935, Einstein, the "old adversary" of quantum mechanics, first pointed out the "absurdity" of "quantum entanglement", and in his paper, published by Podolski and Rosen, criticized the theory of quantum mechanics, thinking that quantum mechanics was incomplete.

According to the "Uncertainty principle" of quantum mechanics, two particles in entangled states, before being "observed", the state is "indeterminate", and if one of the particles is observed, the state of the particle (for example, for a spin) is determined at the same time that the other particle's status is determined (rotated) instantaneously.

This ghostly "transfer" function is not only counterintuitive, but also "contrary" to Einstein's theory of relativity, but this is an indisputable fact, Einstein that quantum mechanics is still flawed, is incomplete.

"God does not roll the dice", this is Einstein's famous quote, and he has been questioning the foundation of quantum mechanics-"uncertainty principle" of the reason, Einstein loathed this "uncertainty." He thinks there must be a better explanation, even a more perfect, more complete theory to explain it.

According to Einstein's theory, the quantum entanglement phenomenon of excluding "uncertainty principle" this explains: As with a glove in two black boxes, it's not sure which one is inside until you open one of them, and once you open a box, when you see this glove, You can immediately determine which gloves are in the other box. Even if these two boxes are at both ends of the Milky Way.

Bohr was one of the most important founders of quantum mechanics, and he put forward the explanation of "quantum entanglement": this phenomenon does not violate the theory of relativity, and in quantum mechanics, you cannot define them before you measure them, and in fact they are still a whole. But after measuring them, they will be out of the state of quantum entanglement.

Einstein's claim was supported by the physicist Schrödinger, Einstein and Schrodinger, who made an indelible contribution to the early years of quantum mechanics, but eventually the two stood in the opposite of quantum mechanics, even the original founder of Quantum theory, because of the appalling "interpretation" and went to the opposite of quantum mechanics.

Although Einstein's explanation is easier to be accepted by the public and easier to understand, it is regrettable that he is wrong. Experiments show that the state of two particles in entangled state is indeed uncertain before being measured, and this uncertainty is fundamentally different from the explanation of "black box gloves".

According to the principle of uncertainty, you cannot predict the state of the particle, the particle, the wave, the particle or the wave, until you observe a particle in the entangled state. Or nothing. Only in the observed moment, it "becomes" the particles you can measure. This explanation, of course, is hard to believe, according to this explanation, when you do not see the moon, the moon will also "divergence" into a group of particles and not waves of things. Even when you close your eyes, the whole world will not exist?

Ming Dynasty thinkers Wang Yangming has a famous saying: "You do not look at this flower, this flower and your silence, when you look at this flower, this flower color for a moment to understand." "This sentence has long been criticized as an idealist remark, which now seems to be a duplicate of the interpretation of quantum mechanics."

Why are these phenomena incompatible with reality? In fact, the interpretation of quantum mechanics is based on the Planck scale or the subatomic scale (very microscopic scale), and the phenomena of life can be explained by classical mechanics. For example, according to the principle of quantum mechanics, if a person keeps hitting the wall, he does have a certain chance to "cross through the walls", but the odds are too small and too small for him to try until the moment when the universe is destroyed.

Modern physicists have seen quantum entanglement as a fundamental characteristic of particles, but scientists still do not know the mechanism.

Based on the "uncertainty principle" based on "quantum entanglement", the scientists put forward the "quantum communication" concept, according to the principle of uncertainty, the transmission of information in a way to fundamentally eliminate the possibility of being deciphered, even if the information is intercepted, its "uncertainty" so that the deciphering can not stop.

The concept of quantum communication (Quantum teleportation) was proposed by American scientist C.h.bennett in 1993. Quantum communication is a communication mode of carrying information by quantum state, which realizes the process of secure communication by using the quantum entanglement principle of elementary particles such as photons. The concept of quantum communication makes Einstein's "phantom (Spooky)"-Quantum entanglement benefit begin to truly exert its true power.

After Bennett put forward the concept of quantum communication, 6 scientists from different countries, based on the theory of quantum entanglement, put forward a scheme of quantum teleportation by combining classical and quantum methods, transferring the unknown quantum state of a particle to another place and preparing another particle to the quantum state. And the original particles remain in place, which is the first basic scheme of quantum communication.

Pan Jianwei, a Chinese youth scholar who studied in Austria in 1997, cooperated with Dutch scholar Pomister to realize the remote transmission of the unknown quantum state for the first time. This is the first time in the world to successfully transfer a quantum state from a photon to a photon in B-place. The experiment transmits only the "state" that expresses the quantum information, and the photon itself is not transmitted as the information carrier. In the September 2009, Pan Jianwei's scientific team built the world's first full-pass quantum communication network on the basis of 3-node chain-like optical quantum telephone network, and for the first time realized the real-time speech quantum secure communication. This achievement is ranked as the international advanced level in similar products, which indicates that the key technology of the quantum network in the metropolitan area of China has reached the requirement of industrialization.

China University of Science and technology Professor Pan Jianwei, Peng, Chenyu and other people, and the Chinese Academy of Sciences Shanghai Institute of Technical Physics Wang Jianyu, photoelectric Technology Research Institute Huang Yongmei and other joint team, in October 2011 in Qinghai Lake for the first successful realization of the hundred kilometers of free space quantum teleportation and entanglement distribution. The successful transmission of 100 km on a high loss ground means that the transmission distance from the low loss space will reach more than 1000 km, which basically solves the problem of long-distance transmission of quantum communication satellite. The breakthrough of the core technology of the quantum communication satellite also indicates that the future construction of the global Quantum Communications network has the technical feasibility.

The theory and phenomenon of "inconceivable", which is not only verified in modern times, but also benefit mankind in the near future.
