In today's information age, the most basic facility is electronic chip, and optical quantum chip is also the infrastructure and core support of the next generation information industry. I wonder if you know the word optical quantum chip?
Perhaps speaking of chips, many people will think of the chip production of Huawei mobile phones. Due to various repression, Huawei was attacked crazily for a period of time, because mask aligner is an important tool for chip development. It is difficult for engraving machines to develop chips.
Recently, China has made great progress in the field of photonic quantum chips, which means that in the field of chip production, photonic quantum chips have a development direction. At this time, the United States cannot sit still. Why can't we just sit back and wait? You know, chip technology has always been monopolized by Americans. In other words, we are hindered in this respect. But now that we have learned this technology, it also means that we have broken the monopoly. Then can't you be angry over there?
When it comes to chips, the most unavoidable thing is Huawei. We know that the president of Huawei has worked hard for many years, and now it can even be said that he has brought Huawei all the way to the peak of technology. At present, Huawei's products are very popular even around the world.
With the emergence of 5G, more and more countries have a new understanding of China. The United States, on the other hand, began to suppress China with all its strength. It is precisely because of American sanctions that Huawei was forced to enter the cold winter of development history almost overnight, and the crisis and opportunities were hidden in the wallet.
Because the United States monopolized the chip market, some of Huawei's businesses had to press the pause button. In this case, China's homemade chips and homemade mask aligner started immediately. Not only the scientific research team, but also domestic enterprises are very busy. However, this is not an easy task after all, and there has been no breakthrough. You know, in this respect, our technical mastery is very immature, and we have to pay more to catch up.
Later, we also read an article published by Academician Guo Guangcan of Chinese Academy of Sciences, saying that China has made a technological breakthrough in optical quantum chips. In recent years, China science and technology market has set off a chip research and development boom. In addition to the research and development of semiconductor chips, we are constantly seeking new breakthroughs in the field of photonic quantum chips, and finally achieve overtaking in corners.
So first of all, what is a quantum chip? Quantum circuit is integrated on the substrate and carries the function of quantum information processing, that is, quantum chip. The manufacturing process of this quantum chip is basically the same as that of the traditional chip. Quantum chip belongs to a new chip based on traditional photoconductor.
This semiconductor material is still different from the previous semiconductor materials, and there are many differences on the basis of composition. Traditional chips form circuits through triode mos transistors. It uses high and low levels to represent binary 0 and 1. However, quantum chips are different. People use different quantum states to represent 0 and 1 in quantum algorithms.
So it can be understood that although the final products are the same, the materials used are different. To give an inappropriate example, like Taobao goods and brand goods, although the appearance is the same, the materials used are definitely different. And if quantum chips appear, they will definitely become the core technology of computers in the future. So, what is a photonic quantum chip? Is there a photonic quantum chip that can bypass mask aligner? Next, let's take a look.
This new photonic chip adopts micro-nano processing technology, so a single chip can integrate a large number of photonic devices. Therefore, the fabrication principle of optical quantum chips is essentially different from traditional chips and quantum chips.
Generally speaking, mask aligner is the core machine of chip manufacturing. In the whole chip processing process, mask aligner can compensate all kinds of optical errors by controlling the energy and shape of the light source, so that it can emit light from the circuit, and then restore the circuit diagram to the silicon chip. Then chemically etched on the circuit network of the silicon wafer.
In this way, the production principle is completely different, which naturally bypasses the restrictions of mask aligner. If optical quantum chips are used all over the world in the future, our researchers will not have to study the 7-nanometer and 5-nanometer technologies of raspberries.
Even the field of chips will directly enter a new era, and mask aligner will directly change from a rare and indispensable object to something that has been severely degraded and ruthlessly eliminated. Just like those bosses who were once alive but were buried in the long river of history.
Some people may not understand. In fact, compared with traditional chips, optical quantum chips are a brand-new chip state. And compared with traditional chips, its biggest advantage is that the stability of photonic chips will be stronger, so the actual performance will be stronger.
Let's just say that the performance of traditional chips mainly depends on the number of integrated transistors. If the transistors are small, the number of transistors that make up the chip will be more and the computing power will be relatively stronger.
People who have a certain understanding of mask aligner should not be too unfamiliar with the technology of chip manufacturing. At present, 7 nm and 5 nm are relatively high-end processes here. Apple 12, Huawei mate40, etc. 5nm chips are used here. However, the 5-nanometer chip technology is currently only owned by Samsung and TSMC. Recently, however, it was reported that Samsung will manufacture 3-nanometer chips.
You know, semiconductor chips are the core of the whole technical field. After all, every technical field is inseparable from the support of chips. Chips are as important as the heart of electronic products. Just like mobile phones, computers and even aerospace in daily life, these little things are inseparable from chips.
Chip is actually the floorboard of all kinds of semiconductor components. All previous chips used purified silicon as the basic material. Things like processors are all made of silicon. Because of its stable physical properties, this element can be used to make chips. Moreover, the cost of silicon is still very low, and it can be purified from sand.
Since the birth of the semiconductor industry, silicon-based chips have occupied an important position. However, with the passage of time and the development of the times, silicon wafers have also encountered the physical limit of Moore's Law. This has also led to the inability of silicon materials to move forward and create brilliant achievements. Therefore, many technology companies began to develop technologies such as electronic chips and graphene chips, and also replaced silicon-based materials with new materials.
Since China was suppressed by the United States, it has started the road of independent research and development of chips. Now, China Yuanyuan Quantum Company is the first company in China to develop and popularize the application of quantum computers.
Moreover, the company also cooperated with Hecheng to build a quantum chip laboratory, the main goal of which is to enable us to complete the design of integrated chips at low temperature. It is worth mentioning that Dr. China University of Science and Technology is a founding team member of this company.
Yuanyuan Quantum Company has made a quantum breakthrough. Quantum technology is actually quite close to our life, and many countries are also studying this thing. China has also made some small achievements in quantum technology. China Photonic Quantum Chip was born. As soon as the news came out, all countries in the world were shocked. America even had the cheek to ask us to share technology.
Since then, the successful research and development of optical quantum chips has declared that the era when China's chip field was blocked by western countries' technology is gone forever, and even the manufacturing technologies of three-nanometer and five-nanometer chips of the world's top chip manufacturing companies are gone forever. What you are proud of will become meaningless. Some people here may ask, what is this optical quantum chip? Why can we get rid of the backward situation of chip manufacturing? How is it different from traditional chips? Can you really change lanes and overtake in one fell swoop?
Due to the long-term blockade of foreign cutting-edge technologies, mask aligner has also become our "heart disease". Especially after the United States restricted the export of chips, in order to overcome this difficulty, the whole country is racking their brains to find ways to break the blockade of foreign chip technology. Is there any way to bypass mask aligner in chip manufacturing?
Just when everyone was at a loss, an exciting news appeared, that is, the team of Chinese Academy of Sciences developed a photonic quantum chip. Once the optical quantum chip is mass-produced, we will completely get rid of the nuclear-free dilemma and no longer have to worry about being stuck by others.
Therefore, researchers in China had to find another way and finally turned their attention to the field of quantum technology. China has been at the leading level in the world in this field. Integrated optical quantum chips were first proposed by British scientists in 2008, and then set off a research boom around the world.
Optical quantum chips were once considered as a stepping stone to the quantum era. Many powerful high-tech enterprises have entered the market one after another, all wanting to eat crabs first and seize the opportunities in the future high-tech market. Optical quantum chips use photons instead of electrons in traditional chips to complete the conversion of photoelectric signals.
As the core component of mobile devices, it is more stable and more powerful than traditional chips. Why do you say that? You know, the performance of traditional chips mainly depends on the number of transistors integrated on them. In other words, the smaller the transistor, the more transistors that make up the chip, and the stronger the computing power.
The difference is that the optical quantum chip takes light as the carrier to replace electricity, and a large number of optical quantum devices are integrated on the chip through micro-nano processing technology. So the integration and accuracy are much higher than the former. The stability will be better, and the performance is incomparable to traditional chips.
If optical quantum chips are mass-produced in the future, our researchers will no longer need to continue to develop three-nanometer chips, and the world chip field will also open a new era. Now everyone is in the era of 5G big data, but the 5G Internet requires computers to have higher performance and lower power consumption.
However, it is difficult for traditional chips to meet these needs, because the mainstream chips at present are all silicon-based chips. Because of Moore's law, it is very difficult to break through this bottleneck, and optical quantum chips can solve these problems.
Optical quantum chips take light as the carrier and have obvious advantages. For example, proprietary information is kept for a long time and is not easily disturbed by the outside world. In addition, the stability is high, and the cost will be reduced after mass production. Therefore, if it succeeds, it will relocate to mask aligner, which has a decisive advantage.
You should know that the physical limit of pure silicon-based chips is seven nanometers. When the silicon atom is less than seven nanometers, electrons will drift and the transistor will have leakage problems. At present, China's mask aligner can only reach 28 nanometers, which is far from the world. There is still a long way to go to reach the highest level.
Although it is enough for daily use as a large electronic device, for small devices such as mobile phones, chips with higher precision are needed. In order to get higher performance in limited space, more advanced chips must be used. Production process.
Seeing this, some people may ask, why didn't our country produce first-class mask aligner? First of all, it's much harder than you think. It takes more than 65,438+000,000 parts to manufacture only one mask aligner. It is absolutely impossible to say that all parts are not imported. Even the Netherlands comes from all over the world. Imported parts, but we were banned from abroad in this respect. At the same time, we also realized the first quantum call with Austria. With the continuous vigorous development of science and technology, quantum technology has gradually entered our daily life, and China has also begun to enter the field of quantum communication.
China has made such great achievements in the quantum field because of the efforts of all the scientists in China. In the field of optical quantum chips, China will break through all obstacles in the near future and successfully produce optical quantum chips on a large scale. We believe that in the coming era of 5G big data, optical quantum chips will play a huge role in more fields and must be the best choice to adapt to the development of the future era.
At that time, those of us who have mastered the latest key quantum technology will no longer have to worry about their lifeline being taken over by others. Of course, we can't slack off because of this. Although China has made a great breakthrough in photonics, there is still a long way to go to realize mass production, but I believe that in the near future, China Heart will certainly illuminate the world.
The era when China people have no core will always be history. Here, we would like to thank thousands of researchers for their contributions to the motherland. China's science and technology can become one of the world powers, each of which plays an indelible role. You have demonstrated to the world with practical actions what a powerful country China is.
Finally, let us pay high tribute to these obscure scientific and technological workers who have devoted themselves to the great rejuvenation of the Chinese nation. They are the pride of the motherland, the backbone of the Chinese nation and an example for each of us to learn. what do you think? Finally, China will be able to achieve chip self-sufficiency in the future and will no longer be subject to people. Today, the sharing of owl technology is here. Welcome to leave a message for discussion. See you next time.
