Zinc oxide (ZnO) quantum dots (QDs) are expected to be not only physically interesting but also a promising platform for qubits. In this work, we demonstrate charge sensing and radio-frequency reflectometry in ZnO double QDs formed in the few-electron regime. These results contribute to the development of qubits based on ZnO devices.
