Researchers led by MIT postdoc Cui-Zu Chang has achieved the first zero-resistance edge state in a circuit. The circuit exhibits the quantum anomalous Hall effect, a property that allows it to transfer information. Superconductors have also achieved zero resistance, but they can only transfer electrical information.
