  In the last years, it was demonstrated that neutral molecules can be loaded
on a microchip directly from a supersonic beam. The molecules are confined in
microscopic traps that can be moved smoothly over the surface of the chip. Once
the molecules are trapped, they can be decelerated to a standstill, for
instance, or pumped into selected quantum states by laser light or microwaves.
Molecules are detected on the chip by time-resolved spatial imaging, which
allows for the study of the distribution in the phase space of the molecular
ensemble.
