Recent advances in experimental techniques offer physicists the opportunity to implement simple systems worth of the “gedanken-experiments” imagined by the founders of quantum theory to address its controversial aspects.
I will present experiments on one of these toy model systems, namely a single 3/2 nuclear spin.
I will first show how, using a single molecular magnet transistor, we can measure an object which otherwise is highly isolated from its environment. I will then present the coherent manipulation of the three possible nuclear spin transitions. Finally I will illustrate how we use this fully controlled 4-level system to explore foundational aspects of the quantum world.
