Abstract

An electronic component is formed by a semiconductor component or a semiconductor-like structure having gate electrode assemblies, for reading out the quantum state of a qubit in a quantum dot. The electronic component comprises a substrate having a two-dimensional electron gas or electron hole gas. Electrical contacts connect the gate electrode assemblies to voltage sources. The gate electrode assemblies have gate electrodes, which are arranged on a surface of the electronic component, for producing potential wells in the substrate.
