The present invention addresses the problem of providing a quantum bit cell and a quantum bit integrated circuit having an easy-to-integrate structure. The quantum bit cell of the present invention including a spin torque oscillator capable of emitting a microwave with a propagation distance of 1 μm or less and having a maximum diameter of 1 μm or less, and a solid-state element quantum bit arranged near the spin torque oscillator at an interval of the propagation distance or less, where a quantum two-level system is controlled by the microwave.
