Abstract

Scalable quantum dot devices and methods are described. An example quantum dot device may comprise one or more repeated cells of a repeating quantum dot structure. The repeated cells may be arranged as a linear array of quantum dots. A single repeated cell may comprise a plurality of quantum dots. The repeated cells may be configured to cause movement of a single electron between adjacent quantum dots. A repeated cell may also comprise a charge sensor for readout of the plurality of quantum dots.
