The invention provides a liquid metal quantum processor, which comprises a current closing path containing a liquid metal knot. The liquid metal knot is composed of at least one basic structure unit,and the basic structure unit is a liquid metal-insulating layer liquid metal. The liquid metal quantum processor provided by the invention is a novel concept macroscopic liquid metal quantum processorbased on a liquid metal flexible material, and the liquid metal junction is easier to cut compared with a traditional Josephson junction made of a solid metal material. The invention is advantageousin that the production cost of the liquid metal quantum processor is reduced, and higher flexibility is provided for intelligent quantum processing.
