Quantum dot devices with fine-pitched gates

Abstract:

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; a first gate above the quantum well stack, wherein the first gate includes a first gate metal and a first gate dielectric layer; and a second gate above the quantum well stack, wherein the second gate includes a second gate metal and a second gate dielectric layer, and the second gate dielectric layer extends over the first gate.
