Abstract

We demonstrate coherent microwave control of the rotational, hyperfine and Zeeman states of ultracold CaF molecules, and the magnetic trapping of these molecules in a single, selectable quantum state. We trap about 5× 10³ molecules for 2 s at a temperature of 65(11) μK and a density of 1.2 × 10⁵ cm^-3. We measure the state-specific loss rate due to collisions with background helium.
