Quantum computation has attracted much attention from both academia and the public due to its great achievements. Along with its fast development and increasing investment, a series of problems are raised. For example, can quantum supremacy be realized? Recently, several results have been reported to address the problem of sampling random circuits, accompanied by classical improvements [1-3]. Another problem worthy of note is how to use a quantum computer. Irrelevant to specific problems that can be solved by a quantum computer, this is actually a problem about how many users can conveniently access quantum computation resources.
