Due to the modification of global chip rules, Kirin chip has become a masterpiece. For this reason, Huawei has increased its R&D investment in the chip field, not only established Hubble to invest in the semiconductor industry, but also developed a variety of new chip technologies. Among them, quantum chip is one of Huawei's research directions, and it has made considerable achievements now.
On November 2, Huawei ranked fifth in the hot search list for the technology for announcing the "superconducting quantum chip patent". This patent has attracted a lot of attention. What is the significance of it?
Huawei Superconducting Quantum Chip Patent Announcement
On November 1, Huawei announced an important patent involving "superconducting Quantum Chip". According to the patent summary, the superconducting quantum chip contains two parts: coupler and controller .
coupler is used for coupling first and second superconducting bit circuits. The frequency response curve of the coupler includes at least one phase inversion point, and the phase inversion point includes a resonant point or pole of the frequency response curve. The
controller is used to adjust the frequency response curve of the coupler so that the bit frequencies of the first and two-bit circuits contain odd phase inversion points. At the same time, the frequency of the phase inversion points is further adjusted so that the equivalent interaction of the cross resonance effect of the first and second superconducting bit circuits is zero.
In fact, to put it simply, this patented technology can reduce the crosstalk between qubit , so that the crosstalk error is significantly lower than the threshold required for quantum error correction.
What is the significance of this technical patent?
First of all, from a technical point of view, being able to reduce crosstalk between qubits is a great improvement.
You should know that crosstalk between multiple bits during quantum computing will generate coupling between signal lines, mutual induction and mutual capacities between signal lines, causing noise on the line. If crosstalk is serious, it will affect the performance of quantum chip design, and overcoming the impact of crosstalk is a key requirement for achieving quantum error correction and large-scale fault-tolerant quantum computing.
Therefore, the research significance of this patented technology is of great significance and lays the foundation for the future research and development of quantum chips.
Secondly, from the perspective of patents, Huawei has seized the initiative by releasing patents in the field of quantum chips.
At present, countries around the world are further making arrangements to make quantum technology explode again and form a trend of a quantum secondary revolution. According to statistics from World Economic Forum , in 2021, the total investment in global quantum computing research is as high as US$25 billion.
shows that quantum technology has become an important entry point for developing scientific and technological strength, and "quantum chip" technology is a good research direction to overcome key technologies in the quantum field and master key applications. If more technical achievements are achieved in "quantum chips" and more patents are obtained, it will definitely be more beneficial.
Huawei has been making arrangements for many years in the field of "quantum chips". It is understood that Huawei began to invest in research and development in 2017 and has obtained many patented technologies. For example, in June this year, Huawei also announced the patented technology: "a quantum chip and quantum computer ".
has now announced the patent for superconducting quantum chips again, indicating that Huawei has been conquering related technologies and has applied for technical patents one by one. The more patents there are, the greater the voice in the core fields. For example, Huawei and , China Academy of Information and Communications Technology, , China Quantum and , Jinan Quantum Technology Research Institute, , etc., have compiled the first domestic quantum random number-related industry standard.
Finally, from the perspective of chips, it is conducive to Huawei's "overtaking on the curve".
Since the global chip rules were modified, Huawei's Kirin chips have been unable to be produced, and its mobile phones have also become chipless. In order to solve these problems, Huawei had to invest in the semiconductor field and seek breakthrough methods.
However, most of the old silicon-based chip design and manufacturing environment, related core technologies and patents are in the hands of the West. If you want to bypass these technologies and achieve "overtaking on a curve", the best way is to take different paths and not follow other people's old paths.
Therefore, Huawei will have some research on chip superposition technology, carbon-based chips, photonic chips and quantum chips. Nowadays, Huawei has announced new patents many times, which is conducive to Huawei's leading edge in terms of quantum chips.
Summary
Perhaps, everyone does not have a deep understanding of quantum technology, but this is a cutting-edge technology that countries and regions are competing to study. Quantum chip technology is one of the key research directions, so Huawei's superconducting quantum chip patents are of certain significance and have a wide range of research value.
Of course, as a scientific enterprise with strong scientific research strength, Huawei's patented technology is naturally of great significance. I wonder, do you think the patented technology is powerful?
