  • Multilevel logic and storage devices on the atomic scale are of great interest as they allow more efficient data storage and processing with a smaller number of logical gates. Here we demonstrate a multilevel atomic quantum transistor, allowing for the gate-controlled switching between different quantized conducting states providing a basis for the future development of novel ultra-small quantum- electronic devices.
