After quantum chips, quantum refrigerators also came out! What is it for?
Affected by the "chip rules", Chinese companies to obtain high-end chips encountered "layers of barriers", the country must not only accelerate the autonomy of the chip industry, but also always beware of the "means" of the old United States, in view of the growth rate of Chinese semiconductors, the Biden team has launched the "lock 14nm chip" plan.
SMIC achieved mass production of 14nm process as early as three years ago, only a foot away from the mass production of 7nm process, but unfortunately could not obtain EUV lithography machine, further improvement of the process was stuck, after the conclusion of the tripartite agreement between the United States, Japan and the Netherlands, the DUV lithography machine for mature processes will also be limited.
The Netherlands has clearly stated that it follows up the new regulations, in the summer will interrupt the supply of DUV lithography machines for Chinese enterprises, only retaining the supply of 38nm lithography machines, it is reported that through multiple exposures, 14nm chip manufacturing can be achieved, but obviously this "loophole" is deliberately left by them, the purpose is to continue to contain domestic lithography machines.
If a road to the field of "silicon-based chips", even if the manufacturing of high-end chips can be realized, it will face a lot of stumbling, and there is a possibility of being "stuck in the neck" at any time, because the chip industry is highly dependent on globalization, and it is difficult to achieve the autonomy of the entire industrial chain in China, so overtaking on the curve has become the main theme.
And quantum chip is the main direction, the first domestic production line has been unveiled, laying the foundation for the domestic chip industry, and recently reported the formation of "quantum chip refrigerator", what is this equipment used for? Will it bring any changes to the development of quantum chips?
The quantum refrigerator is born
At present, the electronic chips used on the market are based on "silicon-based" materials, and the top process has been successfully upgraded to the 3nm level, and TSMC and Samsung have corresponding mass production capabilities, which are expected to be equipped in Apple's next generation of iPhones.
However, in the face of the continuous upgrading of the era of information technology, the subsequent demand for chip performance is becoming more and more prominent, and silicon-based chips are about to face the limit of Moore's Law, the current detectable limit is 1.8nm, which means that after ten years, if there are no alternative semiconductor materials and the birth of technology, the entire chip industry system will be inaccessible.
This is good news for Chinese semiconductors, which has enough time to complete the breakthrough of silicon-based chips, but obviously in the face of a "ceiling" of technology, it is not the best choice for the future, and quantum chip research and development came into being, and China has achieved the mass production of quantum chips, and has achieved independent supporting industries.
CCTV recently unveiled the first quantum chip production line in Hefei, Anhui, according to the visit, the core equipment non-destructive probe station, laser annealing instrument, etc., are all independent by Origin Quantum Company, and also independently developed the quantum chip design software "Origin Kunyuan", which means that from R & D design, to the final manufacturing molding, have been localized.
At present, the finished product "Wukong" has entered the testing stage, and soon the "Wukong quantum computer" will become the strongest existence in China, mastering a large number of core technologies, and ensuring that China is comfortable in the field of quantum chips, but the scope of use of quantum chips is limited, and the finished product cannot be put into use immediately after being manufactured, and preservation has become a big problem.
According to public information, the superconducting materials in quantum chips are very sensitive to the environment, and even have chemical reactions with oxygen and water molecules in the air, which will directly affect the performance of quantum chips, which means that they need to be stored in a vacuum environment.
In order to better store the "quantum chip", the Anhui Quantum Computing Engineering Research Center has set up a project, and recently successfully produced a container called "quantum chip refrigerator", with three preservation chambers, and also equipped with an intelligent monitoring system to better observe the real-time situation inside.
Is China going to lead?
For quantum chips, many people are relatively unfamiliar, it is easy to associate with quantum computers, obviously this is not involved in ordinary people, but for the country's high-end scientific research industry, it plays an extremely important performance role.
Supercomputing is a top existence in the field of computing, many countries do not have similar technology, and quantum computers in computing power, is more than 100 million times supercomputing, traditional computers are limited by chip limitations, can not break through the limit of computing power, and the birth of quantum chips can create infinite possibilities.
With the birth of quantum chip production line, after large-scale mass production, it will be adapted to more industries, and the future will definitely involve all aspects of life, and the country has a complete autonomous system, which is bound to occupy an active position in the future competition.
And today's Europe and the United States no longer have the "spirit of scientific research", have always wanted to maintain the advantage by "eating the old book", and the spirit of Chinese waste of sleep and food, no country can compare, in this competition China has taken the lead, what do you think of this?
