  The electric dipole moment (EDM) plays a crucial role in determining the
interaction strength of an atom with electric fields, making it paramount to
quantum technologies based on coherent atomic control. We propose a scheme for
engineering the potential in a Paul trap to realize a two-level quantum system
with a giant EDM formed by the motional states of a trapped electron. We show
that, under realistic experimental conditions, the EDM can significantly exceed
the ones attainable with Rydberg atoms. Furthermore, we show that such
artificial atomic dipoles can be efficiently initialized, readout, and
coherently controlled, thereby providing a potential platform for quantum
technologies such as ultrahigh-sensitivity electric-field sensing.
