ABSTRACT:
A quantum operational device includes a plurality of quantum boxes arranged in a plurality of stages isolated by a distance which permits tunnelling of electrons or holes through the distance, uses as bit information the presence or absence of an electron or a hole in each of the quantum boxes, and prohibits tunnelling of an electron or a hole from a quantum box in a stage to another quantum box in an adjacent stage when an electron or a hole exists in the quantum box in the adjacent stage. The device only needs quite low power, performs operation at a high speed, and can be fabricated by a simple manufacturing process.
