Abstract
This nonlinear microwave filter is provided with quantum bits that are formed on a circuit board in which target quantum bits are formed which are quantum bits controlled in a superconducting quantum circuit, and that are coupled to a control waveguide to which the target quantum bits are coupled, wherein the distance to a waveguide end in the control waveguide is within a predetermined range from semi integer times the resonant wavelength, the quantum bits have a resonant frequency in which the difference from the resonant frequency of the target quantum bits is within a predetermined range, and the coupling to the control waveguide is stronger by a predetermined value than the coupling between the target quantum bits and the control waveguide.
