The so-called quantum chip is to integrate quantum circuits on the substrate, and then carry the function of quantum information processing.

In view of the development history of traditional computers, the research of quantum computers needs to take the road of integration in order to realize commercialization and industrial upgrading after overcoming the bottleneck technology.

Superconducting systems, semiconductor quantum dot systems, micro nano photonics systems, and even atomic and ionic systems all want to take the path of chip.

From the perspective of development, superconducting quantum chip system is ahead of other physical systems in technology;

The traditional semiconductor quantum dot system is also the goal that people are trying to explore, because after all, the traditional semiconductor industry has been very mature.

For example, once semiconductor quantum chips break through the threshold of fault-tolerant quantum computing in terms of decoherence time and control accuracy, they are expected to integrate the existing achievements of the traditional semiconductor industry, greatly saving development costs.
