ABSTRACT:
A quantum dot logic unit (8) is provided which comprises a row of quantum dots (14, 16, and 18), with each quantum dot separated by vertical heterojunction tunneling barriers (20, 22, 24, and 26). Electric potentials placed on inputs (32, 34, and 36) are operable to modulate quantum states within the quantum dots, thus controlling electron tunneling through the tunneling barriers.
