Abstract

In various embodiments, a quantum object confinement device is provided that includes a plurality of electrodes and is configured to confine one or more quantum objects. Each electrode is configured to generate a confinement potential for confining one or more quantum objects, the confinement potential defining the positions of the one or more quantum objects. The quantum object confinement device includes one or more metasurfaces configured to be associated with the positions of the quantum objects. The metasurfaces are comprised of a plurality of transparent conductive oxide metamaterial structures.
