< electronics , computing > (Or "quantum dot cell") A structure comprising four quantum dots arranged in a square, with two diagonally opposed dots containing electron charges. One diagonal containing charges is arbitrarily defined as representing a value of '1', the other as '0'. In a five-dot cell, the fifth, central dot contains no charge.
