• 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).

  This paper explores the sensitivity gains afforded by spin-squeezed states in atom interferometry, in particular using Bragg diffraction.

  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.

  We present an optomechanical system for in-situ tuning of the coherent spin-motion and spin-spin interaction strength. We characterize the system using measurements of the induced mean-field spin precession. These experiments show approximately a $times2$ variation in the ratio of the coherent to incoherent interaction strength.
