Abstract:
In a quantum computing circuit forming a superconductive loop including a plurality of Josephson junctions, first and second superconductive magnetic flux quantum bit element (101, 102) are biased at a half-quantum magnetic flux, and have mutually different characteristic frequencies. A coupling superconductive magnetic flux quantum bit clement element (103) is located between the first and second superconductive magnetic flux quantum bit elements (101, 102) to perform parametric variable control between the element (101, 102) by supplying a microwave magnetic field pulse which is equal to the frequency difference between the elements (101, 102).
