Illustration showing 2D array of quantum dots

Caption

(a) Scanning electron image of one of the Foundry-fabricated quantum dot devices. Four quantum dots can be formed in the silicon (dark grey), using four independent control wires (light grey). These wires are the control knobs that enable the so called quantum gates. (b) Schematic of the two-dimensional array device. Each Qubit (red circle) can interact with its nearest neighbor in the two-dimensional network, and circumvent a Qubit that fails for one reason or other. This setup is what "second dimension" means.
