Query: Interferometer with a driven trapped ion   We propose an interferometric measurement of weak forces using a single ion
subjected to designed time-dependent spin-dependent forces. Explicit
expressions of the relation between the unknown force and the final populations
are found considering different scenarios, such as the weak force acting on two
branches, on one branch, or having errors in the driving force. The flexibility
to design the trap trajectories is used to minimize errors due to
anharmonicities in the trap. The advantages of the approach are the use of
geometrical phases, which provides stability, the possibility to design
faster-than-adiabatic processes with sensitivity control, and the independence
of the results on the motional states for the small-oscillations regime in
which the effective potentials are purely harmonic.
