QUANTUM DOT DEVICES WITH DOUBLE QUANTUM WELL STRUCTURES

摘要

Disclosed herein are quantum dot devices, as well as related computing devices and methods. For example, in some embodiments, a quantum dot device may include: a quantum well stack including first and second quantum well layers, wherein a barrier layer is disposed between the first and second quantum well layers; a first set of gates disposed on the quantum well stack such that the first quantum well layer is disposed between the barrier layer and the first set of gates; and a second set of gates disposed on the quantum well stack such that the second quantum well layer is disposed between the barrier layer and the second set of gates.
