As we all know, China has always had shortcomings in the field of chips, due to the lack of lithography machines that must be used to manufacture chips, China has not been able to break through the bottleneck of precision chips. Nowadays, foreign chip manufacturing technology has been upgraded from the original 180nm to 5nm, and 3nm technology has also been developed. In fact, in this development situation, silicon chips have approached the physical limit of materials, continue to invest energy in the field of silicon chips, and the potential that can be tapped is very limited. Therefore, finding a material that can replace silicon chips has become an important breakthrough in the development of chips in the future.
With the technology that humans have mastered so far, what materials are likely to replace silicon chips? It is reported that China has found a suitable alternative, and superconducting quantum chips are undoubtedly the best choice. China is at the forefront of the world in the field of quantum computers, and the "nine chapters" quantum computer developed can realize the calculation of 76 qubits, providing a foundation for the development of superconducting quantum chips. Compared with silicon chips, the performance of superconducting quantum chips is more excellent, but it also puts forward high requirements for the development of technology, and there are many difficulties that need to be overcome.
Recently, Zhejiang University has sent out an exciting news, and successfully developed superconducting quantum chips "Mogan No. 1" and "Tianmu No. 1". "Mogan I" is a dedicated quantum chip that uses a fully connected architecture suitable for implementing quantum simulations and precise regulation of quantum states for specific problems. The Tianmu-1 chip is oriented to general-purpose quantum computing and uses a relatively scalable near-neighbor connectivity architecture. With greater programming flexibility to perform more kinds of quantum algorithms, it can be applied to more research fields. It is worth mentioning that China's superconducting quantum chips have realized an independent one-stop system from research and development to manufacturing, which also means that chips can be manufactured by bypassing the lithography machine.
For superconducting quantum chips, there are many different voices on the network. Some netizens believe that the most important task in China at present is to break through the technical barriers of silicon chips, and the development of superconducting quantum chips is a waste of resources and is not yet needed. In fact, superconducting quantum chips can inject vigorous development force into the development of Science and Technology in China, and are pioneers in the field of creating quantum technology, which will help China occupy the initiative in the commercialization of quantum chips and achieve curve overtaking for the United States. At the same time, China has not given up the development of silicon chips, I believe that one day China will be able to master the world's leading chip manufacturing technology.
