Abstract:
1. A quantum information processing device comprising: a resonator incorporating a material containing a plurality of physical systems, each of the physical systems having at least four energy states, transition between two energy states of the at least four energy states, and transition energy between at least two energy states of the at least four energy states, the at least four energy states being non-degenerate when a magnetic field fails to be applied to the physical systems, the transition resonating in resonator mode that is in common between the physical systems, each of the at least four energy states representing a quantum bit, the transition energy being shifted when the magnetic field is applied to the physical systems; and a magnetic-field application unit configured to apply a magnetic field having a direction and an intensity to the material, to eliminate a linear transition energy shift between two energy states included in the physical systems, each of the two energy states included in the physical systems being with excluding the two energy states resonating in the resonator mode.
