Stark- and Zeeman-based decelerators have shown much promise as a route to the full quantum state control of cold neutral molecular samples. Here, we combine Stark deceleration and trapping using a microstructured electrode array with internal state control using a coherent millimeter-wave source. The millimeter wave radiation is coupled to the molecules only microns from the trap electrodes, switching their quantum state. Such on-chip manipulations constitute an important step for future chip-based molecular devices.
