- Abstract summary: We show that spin squeezing can be used to enhance the sensitivity of accelerometry close to the Heisenberg limit.
For a space borne platform in low earth orbit, such a scheme may enable the measurement of the E"otv"os parameter with a sensitivity of the order of 10(-20)

- Abstract: We theoretically prove the feasibility of applying spin squeezing to a light
pulse atom interferometer even in the presence of large momentum transfer using
off-resonant Raman transitions, in order to enhance the sensitivity of
accelerometry close to the Heisenberg limit. We also show how to implement this
scheme in a dual-species atom interferometer for precision test of the
equivalence principle by measuring the Eotvos parameter, and identify the spin
squeezing protocol that is best suited for such an experiment. For a space
borne platform in low earth orbit, such a scheme may enable the measurement of
the E\"otv\"os parameter with a sensitivity of the order of 10^(-20).
