Advancing Quantum Computing with Zinc Oxide Quantum Dots

A New Sensor Boosts Zinc Oxide Qubit Measurement Speed

Researchers at Tohoku University, in collaboration with the National Institute for Materials Science (NIMS) and the University of Tokyo, demonstrated charge sensing, high-frequency reflectometry, and the formation of a few-electron double quantum dot in a zinc oxide (ZnO) device—three key technologies for developing and evaluating spin qubits. Semiconductor quantum dots, like those made of ZnO, are promising building blocks for scalable quantum …
