It should be said that each has its advantages. The difference between a lithography machine and a quantum chip is that the production equipment is a manufacturing tool, and the other is a product manufactured by the equipment. The two are in different positions in the industrial chain. At present, quantum chips have not yet been commercialized, and they are still in a relatively simple integrated circuit state, and have not yet reached the degree of mass manufacturing using large precision optoelectronic devices such as lithography machines.
