• 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).

  We experimentally demonstrate two atom interferometers capable of measuring both the magnitude and direction of applied inertial forces. These interferometers do not rely on the ubiquitous light-pulses of traditional atom sensors. We find the performance of our device to be near the quantum limit for the interferometer size and quantum detection efficiency of the atoms.

A scheme involving high-order Hermite-Gaussian states as probes is proposed for estimating the spatial displacement and angular tilt of light.
