Our research group is developing new architectures for quantum inertial sensors based on cold atoms that incorporate features needed to reduce noise, improve response to dynamics, and improve readout. These features may include novel optical cooling and trapping techniques, integration with nanophotonic optical waveguides, spin squeezing, and atomic state readout based on quantum nondemolition measurement. We are additionally evaluating the potential performance of atom interferometer sensors on real-world platforms.
