PROBLEM TO BE SOLVED: To provide a quantum circuit device for performing an arithmetic operation by using quantum dots capable of realizing stable and high speed operations. SOLUTION: This quantum circuit is provided with asynchronous coupled dots obtained by connecting a main quantum dot 3a to an arithmetic quantum dot 3b whose size is smaller than that of the main quantum dot 3a, asynchronous coupled quantum dots obtained by connecting a main quantum dot 3c arranged apart from the main quantum dot 3a with a distance substantially incapable of tunneling to an arithmetic quantum dot 3d arranged apart from the arithmetic quantum dot 3b with a distance capable of tunneling, and a laser element for emitting a laser beam with wavelength resonating with the inter-level energy of the asynchronous coupled quantum dots to the asynchronous coupled quantum dots. |
