Hundreds of years ago, mankind embarked on the road of science and technology and began a glorious industrial era. As we just walked into the door of science and technology, we were so unfamiliar with everything inside. As time went by, we discovered scientific knowledge, mastered scientific theories, and gained a preliminary glimpse of a corner of science.
The initial scientific research was limited to macroscopic systems, and the mysteries of the world we can see and the material we can see. In the macroscience system, we only see some superficial situations, but we do not know the true inner secrets. For example: when people get sick, the external manifestations are various symptoms. In ancient times, doctors only used their experience to treat these diseases and did not know the secrets behind the disease.
Later, the pace of science continued to move forward, and scientists finally discovered the existence of microscopic world . They dominate the operation of the macroscopic world. The matter we can see in reality is all composed of microscopic particles.
Although we know the existence of the microscopic world, it is very difficult to study their mysteries. We cannot directly observe microscopic particles like we observe macroscopic matter. We need to use various amplification devices. Even so, the microscopic world we can see is just the tip of the iceberg, and there are very few microscopic mysteries found.
Another point is that the physical theory of the microscopic world is very different from that of the macroscopic world. At first, scientists believed that the macroscopic is composed of microscopic, so the physical rules of the two worlds should be the same, but the real research observations surprised us.
The various physical rules of the macro world do not apply to the micro world. The micro world has its own set of physical rules. Many phenomena subvert our cognition, such as superposition states and quantum entanglement, which is completely impossible in the macro world.
By the end of the 19th century, more and more scientists discovered that our existing classical theories could not explain microscopic systems and urgently needed to create a new scientific system. Therefore, with the efforts of many physicists, quantum mechanics was founded in the early 20th century, using the quantum phenomenon that subverts our cognition. Quantum mechanics will also become the discipline that physicists most expect to achieve in the 21st century.
Quantum mechanics is a physics theory that describes atom and subatomic scale. It will completely change people's understanding of the components of matter and bring people to a new world. In the quantum world, there are many phenomena that are very strange, such as: quantum entanglement.
Among the many quantum phenomena, the most attractive thing for scientists is quantum entanglement. Once it can be mastered by us, human technology will enter a new era and may even open up the interstellar era.
So, what is quantum entanglement? Quantum entanglement is a strange quantum mechanic phenomenon. It refers to two quantums in an entangled state. No matter how far apart they are, there will be a relationship. One of the quantum states changes, and the other quantum states will also change accordingly in an instant, ignoring the limitations of space.
quantum entanglement has some similarities with mysterious telepathy. I believe many friends have heard that some twins have telepathy. The two are in different cities. One is injured, and the other can also be sensed instantly. Some scientists believe that telepathy may also be a phenomenon of quantum entanglement.
Quantum entanglement discovered its existence shortly after humans established the quantum mechanics system. However, many scientists are unwilling to believe that it is too subverting our cognition, especially Einstein called it "ghostly ultra-distance action " and believed that it was wrong.
Even if scientists such as Einstein do not recognize quantum entanglement, some scientists continue to move forward on these paths. With the continuous deepening of research, more and more scientists recognize the phenomenon of quantum entanglement. Now, physicists no longer doubt its authenticity, but are thinking about how to study this phenomenon thoroughly and apply it to real science and technology.
2022 Nobel Prize in Physics has been released. Three scientists who received this award are French scientist Alan Aspe , American scientist John Crowze and Austrian scientist Anton Cellinger.
The research directions of these three scientists are the same, that is quantum entanglement. The Nobel Prize of was given to them, which also commends their contributions in "entangling photon experiments, verifying violations of Bell inequality and creating quantum information science ".
Human beings have discovered some mysteries of quantum entanglement. The future direction is to apply discovery to reality and research some technological products, such as: quantum computer , quantum encryption communication, quantum networks, etc.
More and more scientists have joined the research and exploration of quantum entanglement phenomena. The research of the three Nobel Prize winners has cleared some obstacles for us. From a practical perspective, quantum entanglement represents a huge resource. It is still in a blank space and is also the protagonist of a new round of technological competition since the 21st century.
In the 20th century, the emergence of computers changed people's lives. It is a powerful tool that is applied to all aspects of reality and rapidly improving human scientific and technological strength.
21st century, in-depth research on quantum mechanics and the scientific and technological achievements of quantum entanglement will also become a new powerful tool that will change human life again.
So what will quantum entanglement bring to humans? From the definition of quantum entanglement, we can also see that its main application should be in communication, which can achieve instant communication without space.
Human beings have been exploring and researching space for more than half a century. Over the past 50 years, we have gained more understanding of the universe, and more unknowns have continued to appear. We urgently need to go further, explore the farther starry sky, and even walk out of the solar system and explore the extragalactic system.
Interstellar travel, interstellar exploration is not a dream in the future, but in interstellar exploration, communication is very important. Without good communication, you will lose your direction in the universe. The consequence of Star Trek can be said to be dead and lifeless, after all, the universe is so big that it is boundless.
Our existing wireless communication speed reaches the speed of light. This speed can be used on the earth to achieve instant communication. However, in the vast universe in light years, the speed of light is just a turtle's speed. It is too slow. It takes 11 minutes for the signal from the Mars rover to be transmitted back to the earth, while the signal from the Voyager takes 17 hours.
This is just in the solar system, and communication takes such a long time. If it is interstellar exploration, with our existing wireless communication, a communication can be as few as a few years, or as many as decades or hundreds of years, which is completely unfavorable to interstellar exploration.
Therefore, interstellar exploration requires a higher level of wireless communication mode. quantum communication , which is studied in quantum entanglement, is undoubtedly very good. It can ignore distance. Even if the interstellar spacecraft is several light years away from the earth and dozens of light years, it can still achieve instant communication, which is of great significance to human exploration and research.
