Abstract
Quantum dot devices, and related systems and methods, are disclosed herein. In some embodiments, a quantum dot device may include a quantum well stack; a plurality of first gates above the quantum well stack; and a plurality of second gates above the quantum well stack; wherein the plurality of first gates are arranged in electrically continuous first rows and the plurality of second gates are arranged in electrically continuous second rows parallel to the first rows. Quantum dot devices according to various embodiments of the present disclosure are based on arranging first and second gates in hexagonal/honeycomb arrays.
