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.

Abstract: An exemplary quantum dot device can be provided, which can include, for example, at least three conductive layers and at least two insulating layers electrically insulating the at least three conductive layers from one another. For example, one of the conductive layers can be composed of a different material than the other two of the conductive layers. The conductive layers can be composed of (i) aluminum, (ii) gold, (iii) copper or (iv) polysilicon, and/or the at least three conductive layers can be composed at least partially of (i) aluminum, (ii) gold, (iii) copper or (iv) polysilicon. The insulating layers can be composed of (i) silicon oxide, (ii) silicon nitride and/or (iii) aluminum oxide.
