摘要
A functioning logic gate based on quantum-dot cellular automata is presented, where digital data are encoded in the positions of only two electrons. The logic gate consists of a cell, composed of four dots connected in a ring by tunnel junctions, and two single-dot electrometers. The device is operated by applying inputs to the gates of the cell. The Logic AND and OR operations are verified using the electrometer outputs. Theoretical simulations of the Logic gate output characteristics are in excellent agreement with experiment.
