Quality factor determination method and device, equipment and storage medium

The invention provides a quality factor determination method and device, equipment and a storage medium, and relates to the technical field of computers, in particular to the field of quantum calculation and quantum simulation. According to the specific implementation scheme, the method comprises the following steps: simulating to obtain target coupling strength between a target quantum bit and a target control line in a target chip layout; the target coupling strength is the coupling strength between the target quantum bit and the target control line under the condition that the target control line has no preset load; obtaining a target association relationship, wherein the target association relationship represents the relationship among the following three: the coupling strength between the quantum bit and the control line under the condition of no preset load, the Q factor of the quantum bit under the condition that the control line has the preset load, and the gap between the control line and the quantum
