Abstract

Disclosed herein are quantum dot devices, as well as related computing devices and methods. For example, in some embodiments, a quantum processing device may include: a quantum well stack having alternatingly arranged relaxed and strained layers; and a plurality of gates disposed above the quantum well stack to control quantum dot formation in the quantum well stack.
