In quantum logic, a single atomic ion is co-trapped together with a single molecular ion in a radio-frequency ion trap. Similar to strongly coupled pendulums, the two ions share normal modes of motion. This shared motion allows cooling, controlling, and detecting of the molecular ion via the atomic ion.
We will explore new types of quantum superpositions in molecules. One example is putting a single molecule in a quantum superposition of two distinct total-nuclear-spin states. In other words, we will bring a molecule to a quantum state where it has both hyperfine and no-hyperfine energy levels.
