What is quantum teleportation technology? You will understand after reading it.
The present scientific and technological strength cannot be achieved in the future by the following means: 1, ionization magnetic effect 2, quantum involvement technology. The following is the recent domestic media report on the research progress of quantum intervention technology: the so-called "teleportation" technology is to instantly disappear people or objects from one place and reappear in another place. This means that time and space will disappear in the journey, and we can get from one place to another in an instant without taking a physical route. An Australian research team led by China scientists claimed that they cooperated with I BM experts to develop the "instant transfer" technology described in the classic sci-fi movie "Adventures in the Starry Sky", which successfully decomposed a laser beam and instantly collected it in another laboratory without any medium, making the plot in science fiction a reality and making a good start for "instant transfer" in the future. Since the invention of the wheel 5000 years ago, mankind has been looking for a faster way to get from one place to another. The appearance of chariots, bicycles, cars, planes and rockets has greatly shortened the time for human beings to reach specific places. But these methods all have the same disadvantage, that is, they need to take the physical route, and the distance is different, and the time spent is different. So, is there a way to get from home to the supermarket without any means of transportation, or from your backyard to the International Space Station without taking a spaceship? Some scientists devoted themselves to this research and achieved gratifying results. A research team led by Chinese physicist Lin Pingkui of Australian National University recently used a technique called "quantum entanglement" for the first time: destroying a laser beam at one end of an optical communication system and then reappearing at the other end one meter away. On June 17, Australia's Federal Minister of Science, McGoland, presided over a press conference and announced this achievement. The team said that the ultimate goal of teleportation is to send people to a distant place in an instant, just like the movie "Adventure in the Starry Sky", without transportation. Dr. Lin Pingkui said: "This is the scene described in the sci-fi movie Adventure in the Stars (also translated as Star Trek). Starship enterprise is a science fiction technology that can transport astronauts from one planet to another. " The basic unit of light is photon. The so-called "instantaneous beam transfer" is simply to transfer a beam of light from one room to another. The key is to copy the photon data in this beam in another room. The researchers first compiled a radio message into a "photon code" and included it in the laser beam. Then, the researchers combined these laser information with quantum entanglement technology and destroyed them after scanning. However, the password information recorded in the laser beam is saved and sent to the receiving station at the other end in electronic form. The receiving station instantly reads and translates the electronic information, and then restores the laser beam that just contained the specific radio information. Scientists' instant dream transfer The so-called "t eleportation" technology is to instantly disappear people or things from one place and then reappear in another place. This means that time and space will disappear in the journey, and we can get from one place to another in an instant without taking a physical route. This is actually a theory put forward by Einstein, a master of science, which is to dissolve an object into energy, transmit it to a far place, and then restore the energy to an object. 10 years ago, the scientific community considered it impossible. At present, six scientific groups in the world are actively studying. Science fiction stories about delay have a long history. From the space warships in the early Star Wars Adventures and Star Wars, to the time delay number in the Fortress comic book in the 1980s, and even the protagonist Wukong in the Dragon Ball comic book in the early 1990s, they can go beyond the time and space constraints and instantly move to places 654.38+800,000 miles away. In the movie Magic Fly, the protagonist turns himself into a pile of particle codes by instantly transferring the device, and then restores it at the other end of the device. Unexpectedly, a fly entered the device during the period, and as a result, the protagonist mixed with the genes of the fly and became a monster. A few years ago, Jodie Foster's Contact with Time and Space also talked about the transfer of time and space. It can be seen that people's interest in this technology lasted for a long time, because in Ai En Stein's theory of relativity, nothing can travel faster than the speed of light. Therefore, to realize the dream of interstellar flight, human beings must rely on technologies similar to teleportation. For human beings who are eager to break through the three-dimensional space limitation, teleportation is as distant as a time machine, but it is the most attractive dream. 1March, 993, instant transfer finally came out of science fiction and became a theoretical possibility. At that time, American physicist Charles Bennett and a research team of I BM confirmed that instantaneous transfer was feasible. Since then, scientists have done a lot of experiments with photons, proving that instantaneous transfer is actually feasible. 1997, Professor Selinger of the United States proved that light particles can travel a long distance at the same time. 1998, physicists at California Institute of Technology and two research teams in Europe turned the idea of instantaneous transfer into reality. They successfully transferred a photon to one meter in an instant on the coaxial cable. As predicted, when the photon is successfully copied, the original photon does not exist. In 200 1 year, a Danish physicist working in Massachusetts successfully stopped the light beam for half a second, and then found that the light beam ran away at the speed of light. Time travel takes time. The research team led by Dr. Lin Pingkui has 12 members. It is reported that Australian scientists destroyed billions of photons in this experiment and then successfully copied them. This process, called quantum participation, takes only a billionth of a second. The international scientific and technological community believes that this experiment conducted by Australian scientists has opened the prelude to the revolutionary progress of electronic and communication technologies. Dr. Lin Pingkui, who is in charge of this experiment, also believes that the ultimate success of this experiment will enable government agencies, banks and anyone from all walks of life who wants to exchange information at high speed to achieve this goal with incredible speed and absolute confidentiality. However, it seems that it is still far away to experiment with people and other objects in remote teleport mode. Professor Lin Pingkui, who was born in Malaysia, said that the instantaneous transfer and dissemination of organisms is still out of reach, but new technologies still have many uses. Scientists believe that in a short time, this technology can be used to develop supercomputers that are one billion times faster than the fastest computers at present, and the arrival of the quantum information era can be established by improving the efficiency of communication systems. Scientists believe that the new generation of computers will be able to use instant transmission technology to replace wires and chips to transmit information and become quantum computers, which are more efficient and faster than today's computers. Researcher kimble said: "The era of quantum information will come. Although it will not happen in 5 to 10 years, this technology will be very common in 100 years. " In theory, this technology can also transmit objects, and researchers are developing the technology of instantaneous particle transfer. Particles are the basic unit of matter. Australia has taken a rather cautious attitude towards such an experiment. Because although this is an attractive technology, it is too difficult, so before that, few scientists were willing to spend their energy in this field. Only in 1998, California Institute of Technology did a similar experiment. Dr. Lin believes that compared with similar experiments conducted in the United States, the experiments conducted by Australian National University are more reliable and the results are more positive. Dr. Lin also pointed out that the laser beam was destroyed in the experiment and the long-distance instantaneous transmission process was not completed, but the radio signal was intact. Dr. Lin admitted: "There are still some differences between our experiments and science fiction films. For the time being, photons can only be transmitted remotely in the laser, and objects cannot be transferred instantly. " Dr Lin has published many valuable papers. He said that the goal of his research is to prove that instant transfer can be done, which is useful for the future development of technology. A reporter once asked him why he locked his research field in the instantaneous transfer of light. He replied humorously: "That's because it is easier to study optics than mechanical applications." He said that ordinary people rely on Newton's physical theory to predict the running route of a football or where the plane will land, but in the quantum world, a world smaller than the atomic world, the general experience of physics is untenable, and you will find many wonderful things happen, and particles seem to appear in different places at the same time. Physicists call the state of quantum "supernatural". The focus of scientists' next research is to instantly transmit real objects larger than photons to distant places. Dr. Lin said: "I think it is feasible in principle, but it may be a thousand years later." For example, what we have invented now can only be regarded as an abacus (quantum instantaneous transfer), which is far from being a supercomputer (instantaneous transfer of organisms).
