What do you mean by the new progress in quantum chip research and development?

In recent years, the popularity of chips has not dropped, especially with the large-scale development of 5G and the development of new energy vehicles, the demand for chips has reached an unprecedented level. Therefore, there has been a "chip shortage" all over the world. As the world's largest importer of chips, China is increasingly affected. However, although some chip purchases are still subject to overseas companies, the good news is that this situation will be greatly improved in the future. Because the quantum chip is coming. If the quantum chip can be successfully developed, it will completely change the current situation.

Perhaps many people are not familiar with quantum chips. But it was developed in an electronic power.

So what is a quantum chip?

Quantum chip is a quantum circuit integrated on the main panel, so it is a quantum information processing function. Based on the quantum mechanical characteristics of superposition and entanglement, quantum computers can achieve a leap in computing power far beyond classical computers, and are known as "nuclear weapons" in the information age, which is related to the core competitiveness of the country in the future. And quantum chip is the core of this subversive technology.

Similar to the CPU in the classic computer, the quantum chip is the central processing unit of the quantum computer, also known as QPU(Quantum Processing Unit), which integrates the computing unit of the quantum computer-quantum bits. The more mature the manufacturing process of quantum chip is, the more qubits are integrated, and the more powerful its computing power is. Theoretically, a quantum computer with 300 qubits can calculate more data than the sum of atoms in the whole universe.

At present, the fastest progress is superconducting quantum technology. From 20 19 to 10, Google achieved quantum superiority with 53-bit superconducting quantum chips, which proved that quantum computers surpassed classical computers in a specific problem (random quantum circuit sampling).

Domestic quantum chip

According to the latest news, Hefei Benquan Quantum and Hefei Jinghe Integrated Circuit Company have signed a cooperation agreement, and the two sides will jointly build a joint laboratory of Benquan Quantum and Quantum Chip.

According to the plan, this laboratory will realize the whole chain development from quantum chip design to packaging test. In other words, domestic chip companies will surpass traditional chip designers and manufacturers by developing quantum chips.

It is worth mentioning that at present, domestic quantum chip production is still mainly based on laboratory processing. To realize the large-scale production of quantum chips, mature manufacturing technology and mature production and processing mode are needed.

In fact, the ultimate goal of the two companies to build a laboratory is to make the production line of quantum computing chips land as soon as possible, which is also the biggest obstacle to the development of the domestic quantum computing industry.

As for the establishment of the joint laboratory of origin-crystal and quantum chips, American Academician James even bluntly said that it is impossible for the United States to make a fuss about chips in China in the future, and the chip war will eventually come to an end. I believe that China's quantum chips will shine brilliantly in the world in the future.
