Atom Interferometry in Space for Fundamental Science and Practical Applications

Abstract

Recent progress in cold atom interferometry has lead to a new way of sensitive inertial sensing. Significant performance enhancement of cold atom interferometer-based sensors is anticipated when operated in the microgravity environment in space. We are developing a quantum gravity gradiometer based on the atom interferometer techniques for satellite-based global gravity field mapping. The same technology can be employed for tests of fundamental physics. We will discuss some of the possibilities and describe the implementation of our atom interferometer system.
