Artists impression of the spin-detection single molecule shuttle. The Buckyball containing the Nitrogen (or Phosphorous), is held between two gold electrodes by linking flexing molecules (shown schematically as springs). The shuttle picks up an electron (shown as glowing ball), from one electrode and then moves to the other electrode to dump the electron. The average current depends sensitively on the equilibrium position of the shuttle and via the interaction of the shuttle's spin and nearby (unshown), nanomagnet. Credit: Jason Twamley

“We are trying to understand quantum nano-electro-mechanical systems,” Jason Twamley explains to PhysOrg.com. “These systems display richer dynamics and interactions than one can obtain with quantum optical systems, because it’s very hard to get photons to interact with each other.”
