The computer revolution! US containment of China targets Quantum China | US | Quantum
US President Biden recently signed an executive order to establish an outward investment review mechanism, restricting US entities from investing in China's semiconductor and microelectronics, quantum information technology, and artificial intelligence fields. Analysis suggests that the US's practice of restricting overseas investment to curb China's development of quantum technology has limited impact.
Quantum computers will surpass artificial intelligence and become the forefront of technological breakthroughs
When it comes to disruptive technology, quantum computers are the shining stars in the current technology industry. What is a quantum computer? Simply put, when a device processes and calculates quantum information while running quantum algorithms, it belongs to a quantum computer. In the face of quantum computers, traditional computers are like 'abacuses'.
Famous physicist Kaohsiung Ka Lai pointed out in his book "Quantum Hegemony: How the Quantum Computer Revolution Will Change Everything" that the development of quantum computing is at an important turning point.
Theoretical physicist Ka Lai Daoxiong
We have gone through three basic stages of the computer revolution. The first stage is when we use sticks, stones, levers, gears, pulleys, and ropes for calculations, which is the first simulation stage; Then it was World War II, when we began using electricity and transistors. This leads us towards today's microchip and digital revolution, and we are now in the second stage, which is the stage of 1 and 0 bits and bytes. But nature will laugh at us because it does not use a combination of 0 and 1 to calculate, but rather calculates based on electrons, electron waves, and the waves that produce molecules. That is why we are now entering the third stage.
Jialai Daoxiong said, imagine a mouse in a maze. The digital computer will calculate one by one the different route plans made by the mouse at each fork in the road or maze where decisions need to be made, which takes a long time. Now, quantum computers can immediately analyze all possible solutions and trajectories simultaneously. This seems to violate human common sense that humans cannot appear in two places at the same time. But accept reality, in quantum theory, you can appear in many places simultaneously. This is the power of quantum computers.
Superconducting quantum computers have astonishing computing power
In 2019, a quantum artificial intelligence research team from Google developed a quantum computer with 53 superconducting qubits and demonstrated powerful computing power. In solving a specific complex computational task, this superconducting quantum computer can successfully complete the task in just 200 seconds. If the world's top ranked supercomputer was used for calculation, it would take up to 10000 years to achieve.
The core component of quantum computers is quantum chips
Unlike the core component CPU of traditional computers, the core component of quantum computers is quantum chips. Due to the fact that the quantum computing system is still in its early stages, researchers from various countries need to invest a lot of effort not only in these chips, but also in the infrastructure required to drive them.
At present, quantum computers are still in the stage of development from laboratory research and development to enterprise productization.
Google team research to further upgrade superconducting quantum computing system
In February 2023, Google's quantum artificial intelligence research team further upgraded the superconducting quantum computing system, which originally only had 53 qubits, to 72 qubits and successfully verified the feasibility of quantum error correction solutions. This also means that people are one step closer to truly practical quantum computers in the future.
Japan's first domestically produced quantum computer officially put into use
On March 27th, Kyodo News Agency reported that Japan's first domestically produced quantum computer, developed by the Japan Institute of Physics and Chemistry and others, was officially put into use on the same day. Like the technology used by Google and IBM in the United States, Japan's first domestically produced quantum computer also uses a superconducting circuit with zero resistance at extremely low temperatures to prepare the basic unit of information for calculation - quantum bits.
China Successfully Developed "Zuchongzhi II" with Advanced Computing Speed
In 2021, the Chinese superconducting quantum computer "Zuchongzhi 2" was launched. The superconducting quantum computer has 66 quantum bits and is nearly 10000 times faster in terms of computational speed than the system released by Google in 2019.
On May 31st, the "Zuchongzhi" quantum computing cloud platform was officially launched and opened to users worldwide. In June of this year, Chinese scientists announced that their quantum computing device "Jiuzhang" could perform some of the tasks commonly used by artificial intelligence at a speed 180 million times faster than the world's most powerful supercomputer.
Chinese Scientists Realize the Preparation of 51 Superconducting Quantum Bit Clusters
Recently, a Chinese scientific research team has successfully developed the first generation of commercial grade semiconductor quantum chip circuit boards, which can support the packaging and testing needs of up to 6 bit semiconductor quantum chips, allowing semiconductor quantum chips to interact and connect with other key core components of quantum computers more efficiently, fully leveraging the powerful performance of semiconductor quantum chips.
Zhu Xiaobo, Chief Quantum Computing Engineer of "Zuchongzhi"
The direction of superconducting quantum computing is highly valued by various countries due to its inherent advantages, but it is the field with the most investment. In the field of quantum computing, we belong to the world's leading level. In the field of superconducting quantum computing, we believe that we are in the world's first square.

Analysis: The US's approach to curbing China's development of quantum technology has limited impact
Quantum computing technology is a disruptive technology that relates to the fundamental computing capabilities of future development. Whoever first masters the key core technology of quantum computers can occupy the high ground of the quantum information era. Analysis suggests that as China promotes the localization of technology, the US's practice of restricting overseas investment to curb China's development of quantum technology has limited impact.
