Old technology lithography machines are no longer an obstacle to Huawei’s modern quantum chips

Huawei continues to conduct chip research and has accumulated deep chip experience. It has had great success with chips in the areas of cell phones, base bands and servers. However, Huawei has expanded the field of chip research and development and has made corresponding breakthroughs in targeting quantum chips.

According to Huawei’s official announcement, it has released a patented quantum chip technology, which is of great help in solving the efficiency problem. What is Huawei’s intent for quantum chips? Can the development of quantum chips break the dependence on lithography machines?

Huawei announces patent on quantum chip

Research advances in quantum are increasingly being explored in the industry, and many reports have come one after another. For example, Professor Pan Jianwei of the University of Science and Technology of China led the team to achieve breakthroughs in the quantum computing prototypes of “Nine Chapter One” and “Nine Chapter Two.”

There is also Alibaba’s successful breakthrough in the new superconducting quantum field, with a two-bit gate control accuracy of 99.72%, setting a new world record.

There are many similar cases of breakthrough progress in China, which are essentially related to quantum computing and quantum chips. Let people gradually realize that quantum technology has gradually moved from theory to reality, and it may also enter life in the future, and become an important technology to promote the development of science and technology.

In the field of quantum technology, Huawei has officially announced that it has obtained a patented technology for quantum chips.

On June 10, Huawei announced an invention patent titled “A quantum chip and quantum computer.” The summary shows that this patent covers quantum processing technology, which is mainly used to solve the problems of the difficulty of producing quantum chips and low yield.

If Huawei had not announced this patent, many people might not know that Huawei also has a job in the field of quantum chips. In the past, Huawei’s chip research and development has focused on cell phones, base bands and other areas, and has developed a range of chips, such as Kirin, Honghu, Kunpeng and Balong. But in the field of quantum, what kind of layout has Huawei made?

In fact, Huawei has been working on the layout of the quantum field for a long time. In January 2021, it announced a patent titled “A quantum key distribution system, method and equipment,” which is mainly used in the field of quantum key communication. If nothing else, Huawei can explore quantum communication according to this patented technology.

Whether it is quantum chips or quantum communications, Huawei’s exploration of the layout has proven that it will continue to move forward in the field of quantum, and there is a tendency to accelerate. Perhaps it is to keep pace with the trend of scientific research, or Huawei has found a new direction for chip development.

Huawei began to explore the direction of chip development regularly. Before the announcement of the quantum chip patent, Huawei also announced two patents related to chip stacking. Will this be a different path? Very likely.

However, quantum chips have not yet been widely used, and there is still a long way to go before they are normalized. In the future, to advance the landing of quantum chips and develop industrial manufacturing, can we break the dependence on lithography machines?

Can the development of quantum chips break the dependence on lithography machines?

Almost all chips on the market must be manufactured by a lithography machine, and under the operation of the lithography machine, the lithographic exposure is realized on the silicon wafer. To produce high-end chips, an EUV lithography machine must also be used to process high-end nanochips with an EUV light source with a wavelength of 13.5 nm. It can be argued that a lithography machine is an essential tool for chip fabrication.

But can the development of quantum chips break the dependence on lithography machines? Or is there an indispensable demand for lithography machines?

If you understand the principle of quantum chips, you can get the answer. Quantum chips differ from ordinary silicon-based chips, and there are major differences in materials. If silicon-based chips are made of silicon materials, then quantum chips only use quantum collisions to realize the interaction of information.

In the whole manufacturing process, there is no dependence on the lithography machine. Therefore, there is no demand for lithography machines in the future development of quantum chips. No matter how advanced the lithography machine is, it will not affect the sustainable development of quantum chips.

How quantum chips should be industrialized is another matter. After all, silicon-based chips already have a globalized manufacturing model for the industrial chain, and hundreds of manufacturers are involved in all aspects, from design to manufacturing.

How do quantum chips go industrial?

The quantum chip seems to be still in the laboratory stage, and how to make the quantum chip commercial is a brand new problem.

There must be a complete set of production links. The good news is that domestic manufacturers have already made layouts in the industrial design software of quantum chips.

Hefei Yuanyuan Quantum participated in the development and launched the Yuanyuan Kunyuan Q-EDA software. This is the first industrial-level quantum chip design tool in China, providing design-level support for domestic manufacturers to develop quantum chips.

Contacting Huawei’s launch of quantum chip technology, if necessary, this Yuanyuan Kunyuan may come in handy.

The emergence of Yuanyuan Kunyuan has taken a key step in the industrialization of quantum chips. Next, more domestic manufacturers are required to make research breakthroughs and establish a solid foundation in the field of quantum chips. There is no need to think about the lithography machine in the development process, which means that valuable time can be spent where it is needed. It is expected that Huawei will make more quantum chip breakthroughs after this.

Summarize

Huawei announced the patent research on quantum chips, which is a rare research achievement in the field of quantum chips by Huawei in recent years. But it also further proves that Huawei’s chip layout is diversified. Huawei will strive to implement any opportunities for breakthroughs, so that the development of domestic chips can achieve more brilliant achievements.
