Quantum devices, quantum logic device, a logic circuit according to a driving method and quantum logic device of the quantum logic device

A to achieve the performance that surpasses the current CMOS technology in terms of miniaturization and power consumption, and provides a technique capable of realizing a logic circuit implementation and not inconsistent method of classical computer using existing sequential circuits . A first conducting member 101a having a two-dimensional electron gas in the xy plane carrier is confined in the z-direction, 101b and the second conducting member 102a, the electric field that gives the 102b, first conducting member 101a, the influence of the 101b the third conductive member 103a for generating, 103b and the first conducting member 101a, 101b and the second conducting member 102a, the easier the insulating member 104 to flow a tunnel current between 102b, first conductive member 101a, 101b and third conductive member 103a, and a hard insulating member 105 passing a tunnel current between the 103b, the third conducting member 103a, the electric field generated by the potential applied to 103b, the first conductive member 101a, affecting 101b of the sub-band .
