Quantum chip is to integrate quantum circuits on the substrate, and then carry the function of quantum information processing. Drawing on the development history of traditional computers, quantum computer research needs to take the road of integration in order to realize commercialization and industrial upgrading after overcoming bottleneck technology. Superconducting systems, semiconductor quantum dot systems, micro-nano photonics systems, and even atomic and ion systems all want to go the way of chip. From the development point of view, the superconducting quantum chip system is ahead of other physical systems in technology; Traditional semiconductor quantum dot systems are also the target of people's efforts to explore, because after all, the development of the traditional semiconductor industry has been very mature, such as semiconductor quantum chips in decoherence time and control accuracy once the threshold of fault-tolerant quantum computing, is expected to integrate the existing achievements of the traditional semiconductor industry, greatly saving development costs.
