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, the quantum well stack includes a quantum well layer, the quantum processing device further includes a plurality of gates above the quantum well stack to control quantum dot formation in the quantum well stack, and (1) gate metal of individual gates of the array of gates is tapered so as to narrow farther from the quantum well stack or (2) top surfaces of gate metal of individual gates of the array of gates are dished.
