Preface
Recently, China has just announced a new news, it is the mainland has made another breakthrough in quantum technology, mastered a "black technology", not long after the news was announced, the United States could not hold back, and immediately imposed sanctions on Chinese enterprises.
So what kind of "black technology" will make the United States panic and can't wait to impose sanctions on Chinese companies as soon as it appears?
"Black Technology"
Over the years, the Chinese Academy of Sciences has been committed to the study of quantum science, and through continuous experiments and breakthroughs, quantum technology has been continuously updated and has more efficient performance.
On May 9, the Chinese Academy of Sciences held a press conference to show the new quantum technology to the media, the public, professionals, etc., and also to the world.
This breakthrough has largely relied on the Hall effect, which has been a top-down approach in past quantum Hall effect studies.
Based on the original materials, the quantum Hall state is then realized through the structure and properties of these materials themselves.
The use of this method is very demanding, to maintain a low temperature environment, but also to have high-purity two-dimensional materials and strong magnetic fields, it is often difficult to meet all of them, and the variables are relatively large, and it is very difficult to operate.
This time, however, scientists have changed their thinking and adopted a "bottom-up" approach, which is different from traditional methods in that it is more flexible and easier to control, allowing for better control of the materials and processes of the experiment.
If we put it more simply, in fact, we can think of the quantum Hall effect as a house, and the traditional method is to add and transform the original house.
The new method is to break and rebuild, accurate to every brick and tile, and control the whole process of building a house, so as to build a brand new house.
This time, the institute has successfully achieved a nonlinear interaction between photons using a new type of superconducting qubit developed by itself.
China Science Daily, 2024-05-07, "International First! Continental has made a major breakthrough in the field of quantum computing》
Thus, the equivalent magnetic field acting on photons is further constructed to construct an artificial gauge field, and the fractional quantum anomalous Hall state of photons is realized for the first time in the world.
This new breakthrough in quantum technology is likely to cause a new round of scientific and technological revolution in the world, and this breakthrough is not only the progress of China's science, but also allows China to have more voice in the international community and win a certain competitive advantage and status.
The Paper, 2024-05-14, "From Quantum Communication to Quantum Computing, How China's Quantum Information Technology Moves Forward with Quantity"
In most countries, science and technology are the primary productive forces, and with certain scientific and technological means, they can play a major role in social development, military security, and telecommunications, and enhance China's international strength.
That's why this time, the United States can't wait to impose sanctions on China after the news comes out.
But after all, they are unknown, so they have found some high-sounding reasons to take advantage of the opportunity to sanction Chinese companies in the name of "wandering".
Guoxin Online 2024-05-10The United States Adds 37 More Chinese Enterprises to the Entity List (with List)
"Exile, sanctions"
On May 9, the U.S. Department of Commerce announced that all 37 Chinese companies were added to the so-called Entity List.
The reasons for the U.S. sanctions on these companies involve military security, information, etc., and 11 of them have also been included in the sanctions list because of the "stray balloon" incident.
However, in fact, the "stray balloon" incident happened last year, but now it is being used by the United States as a reason for sanctioning Chinese companies, which is really unconvincing, and it is difficult not to make people feel that they are taking the opportunity to abuse their power and suppress the mainland.
In February last year, a Chinese civilian unmanned meteorological airship appeared in the sky over the United States, which was very large and conspicuous, and was seen by many people and uploaded videos and photos on the Internet.
For a while, it caused heated discussions on the Internet and also attracted the attention of the US government, when the United States saw this balloon and thought that it was sent by spies to steal US secrets.
Later, after checking it, it was found that the balloon seemed to be from China, and immediately concluded that it was a spy sent by China, describing it as a "spy balloon" specifically to steal American information and disrupt American society.
After learning of the incident, China also immediately responded, denying the US accusations, not admitting that the balloon was Chinese, and also stating that China had never sent spies to investigate US intelligence.
However, at that time, the United States insisted that China was responsible for this incident, and did not listen to our explanation or response at all, and still placed this charge on China's head, and used it to trumpet China's badness, accuse China of being a villain, and later suspected of using force to shoot down the balloon.
A few months later, the U.S. military suddenly released a message claiming that the "stray balloon" had not done anything to collect U.S. intelligence, and admitted in disguise that it had wronged China.
From the very beginning, without any conclusive evidence, they decided that China was the devil, and used online speech to crusade against China and smear China, completely ignoring explanations.
But it didn't take long for him to come out and slap himself in the face to correct China's name, and the attitudes before and after were simply two extremes, how rampant the accusations against China were in the front, and how gray and slippery the back was.
Moreover, they only explained the truth, did not apologize for their previous actions, and did not explain the question of who the balloon belonged to, which seemed to be a farce directed and staged by themselves.
The drama should have ended with the U.S. military's response, but who knows that it will be brought up again a year later, and this time it will still be aimed at China.
This time, the U.S. has added eight companies on the grounds that it supports high-altitude balloons flying over the United States in 2023, and three more companies on the grounds that it has ties to companies related to stray balloons.
The United States admitted it at the time, but now it is suddenly using last year's incident as a cover to sanction Chinese companies, obviously deliberately finding reasons to do so, in order to suppress China and curb China's development.
Judging from these actions of the United States, they still can't hold their breath at all, and when China is a little troubled, they immediately take obstructive measures, and even the reasons are full of loopholes, which looks a little ridiculous.
