Huawei once again broke through the barrier: officially announced quantum chip technology. It is understood that the patent relates to the field of quantum computers to solve the problems of difficult fabrication of quantum chips and low yield. Huawei once again broke through the barrier: officially announced the quantum chip technology.
Huawei Breaks Barriers Again: Officially Announces Quantum Chip Technology 1 Recently, Huawei, the most powerful technology enterprise in China, announced the patent of "a kind of quantum chip and quantum computer". This is not the first time it has published a patent for quantum chips. Last year, it was authorized to disclose a patent related to a quantum key distribution system, method and equipment, which shows that it has made another breakthrough in quantum chip technology.
China keeps betting on quantum chip technology, because this brand-new chip technology will get rid of the dependence of silicon-based chips on mask aligner technology. Because mask aligner's industrial chain is in the hands of Europe, America and Japan, it is difficult for China to obtain advanced EUV mask aligner under the current circumstances, so China has been trying to explore new chip routes.
Quantum chip is just the route that China's scientific and technological circles continue to invest. As early as June 2020, the research teams of China University of Science and Technology and Zhejiang University have made a breakthrough in the theory of quantum chip technology, which was published in Physical Review Express and Science. Since then, China has begun to increase its quantum chip technology.
In 2020, China developed "Jiuzhang No.1" and launched "Jiuzhang No.2" in 20021year. These two quantum computers take the route of optical quantum technology; China University of Science and Technology cooperated with Shanghai Microsystems of Chinese Academy of Sciences to develop "Zu Chongzhi II", taking the superconducting quantum route, thus China is in the leading position in quantum computing technology in the world.
However, these quantum computers are all prototypes and are relatively large. Quantum computers have really become practical and need to be improved. Therefore, the research and development of quantum chips has become the focus of further promoting the commercialization of quantum computing in China. As a leader in China's chip industry, Huawei has no hesitation in shouldering the heavy responsibility.
In fact, Huawei has been developing quantum chips for many years. It is estimated in the industry that it began to develop quantum chips as early as 20 17, so it can obtain the patent of quantum chip technology in 20021year. Now the patents of quantum chips have been announced one after another, which represents the accelerated progress in the research and development of quantum chip technology.
Huawei's Hisilicon chip represents the most advanced chip technology in China. Its Kirin chip is on a par with Qualcomm, the boss of mobile phone chip, which promotes Huawei's mobile phone to form a tripartite confrontation with Apple and Samsung in the global high-end mobile phone market. In 20 19, its Kunpeng 920 chip broke the bottleneck of ARM architecture server chip. After several years of development, Kunpeng 920 chip has gained a place in the domestic server chip market.
Since Q4, 2020, Huawei has no chip foundry company to produce chips for Huawei, which is a well-known reason. Huawei's performance has suffered heavy losses, and its revenue in 20021year has dropped by more than 200 billion. However, it was not discouraged and continued to increase investment in technology research and development. Huawei Hisilicon continued to strengthen chip technology research and development.
It is precisely because of Huawei's insistence that Huawei Hisilicon has continuously made technological breakthroughs in quantum chips. It may become a pioneer in promoting the commercialization of quantum chips. After all, its chip technology research and development strength is strong enough.
Another driving force for Huawei to continuously develop quantum chips is undoubtedly to break the current chip manufacturing problems. Due to various reasons, Huawei's chip OEM problem still faces many obstacles. Once quantum chips are commercialized, the technology of silicon-based chips will be innovated, and mask aligner will no longer be an obstacle. By then, Huawei will become a leader in the global chip industry.
China's chip industry is now highly prosperous, and it has a layout in many aspects of chip technology. It is believed that with the joint efforts of the chip industry in China, China chip will eventually go out of its own unique road, completely overcome the restrictions of overseas chip industry chain, and usher in its own spring.
Huawei breaks the barrier again: officially announces quantum chip technology 2. It is learned from the enterprise search website that today, Huawei Technologies Co., Ltd. announced an important invention patent "A quantum chip and computer", with the publication number of CN11413758a, and the application time was June 2020.
It is understood that the patent relates to the field of quantum computers to solve the problems of difficult fabrication and low yield of quantum chips.
The patent abstract shows that in the quantum chip provided by this application, the quantum chip is composed of m sub-chips, which will effectively reduce the manufacturing difficulty and improve the manufacturing yield; Moreover, when a sub-chip has quality defects, it will not lead to problems such as high cost and waste of resources caused by quality defects.
According to Baidu Encyclopedia, a quantum chip integrates a quantum circuit on a substrate and then carries the function of quantum information processing. It mainly adopts superconducting system, semiconductor quantum dot system and micro-nano photonics system.
It is worth mentioning that in April this year, Huawei disclosed a patent for chip stacking and packaging and terminal equipment, and the application number was CN 1 14287057A, which can solve the high cost problem caused by the adoption of silicon via technology.
According to reports, the patent relates to the field of semiconductor technology, which can solve the high cost problem caused by the adoption of silicon via technology while ensuring the power demand.
Huawei breaks through barriers again: quantum chip technology is officially announced. On June 3rd10, Huawei Technologies Co., Ltd. published the invention patent "A Quantum Chip and Quantum Computer" with the publication number of CN114613758a.
The patent abstract shows that the application provides a quantum chip and a quantum computer, and relates to the technical field of quantum computing, so as to solve the problems of great difficulty in manufacturing quantum chips, low yield and the like.
The quantum chip provide by that application comprises:
A substrate, m sub-chips, a coupling structure and a cavity mode suppression structure;
Each sub-chip comprises n qubits, and m sub-chips are arranged on the surface of the substrate at intervals;
The coupling structure is used to realize the interconnection between m sub-chips;
Cavity mode suppression structures are arranged at the edge of each sub-chip and/or in the gaps between m sub-chips for increasing the cavity mode frequency of quantum chips.
Where m is a positive integer greater than 1 and n is a positive integer greater than or equal to 1.
In the quantum chip provided by the application, the quantum chip is composed of m sub-chips, which effectively reduces the manufacturing difficulty and improves the manufacturing yield; Moreover, when a sub-chip has quality defects, it will not lead to problems such as high cost and waste of resources caused by quality defects.
Huawei has also explored quantum technology before. 202 1, 1, 12, Huawei Technologies Co., Ltd. was authorized to disclose the patent related to "a quantum key distribution system, method and equipment", with the publication number of CN 108737083B.
In June, 20021,the Ministry of Industry and Information Technology issued the first domestic industry standard of QKD based on BB84 protocol, Part III: Quantum Random Number Generator (QRNG), which was led by Guo Dun Quantum and compiled by China Xintong Institute, Guo Ke Quantum, Huawei and Jinan Institute of Quantum Technology.
