QUANTUM INFORMATION PROCESSING SYSTEM AND QUANTUM INFORMATION PROCESSING METHOD OF QUANTUM INFORMATION PROCESSING SYSTEM

A quantum bit array including a plurality of quantum dots capable of confining a quantum bit and a plurality of gate electrodes used to control of the plurality of quantum dots, and a control device controlling a plurality of quantum bits using the plurality of gate electrodes, the quantum bit array includes a storage region including a plurality of quantum dots storing the quantum bit, and an operation region including a plurality of quantum dots capable of applying a quantum gate operation of changing a spin state to the confined quantum bit, the stored quantum bit is moved from the storage region to the operation region by a shuttle operation of moving the quantum bit with a Coulomb force generated by using the plurality of gate electrodes, and the quantum gate operation of changing the spin state to the quantum bit is performed in the operation region.
