Applying a small voltage causes an atom to relocate, turning the switch on or off. ETH Professor Mathieu Luisier, who participated in this study, simulated the system using Piz Daint Supercomputer. «The simulation at Piz Daint was essential in order to prove that the circuit works indeed with a single atom», Luisier says.
