• Abstract: Recent advances in cold atom interferometry have cleared the path for space applications of quantum inertial sensors, whose level of stability is expected to increase dramatically with the longer interrogation times accessible in space. In this study, a comprehensive in-orbit model is developed for a Mach-Zehnder-type cold-atom accelerometer. Performance tests are realized under different assumptions, and the impact of various sources of errors on instrument stability is evaluated. Current and future advances for space-based atom interferometry are discussed, and their impact on the performance of quantum sensors on-board satellite gravity missions is investigated in three different scenarios: state-of-the-art scenario, near-future (between the next 5 and 10 years) and far-future scenarios (between the next 10 to 20 years). We show that one can achieve a sensitivity level close to 5E-10 with the current state-of-the-art technology. We also estimate that in the near and far-future, atom interferometry in space is expected to achieve sensitivity levels of 1E-11 and 1E-12, respectively. A roadmap for improvements in atom interferometry is provided that would maximize the performance of future CAI accelerometers, considering their technical capabilities. Finally, the possibility and challenges of having ultra-sensitive atom interferometry in space for future space missions are discussed.

  We present a new approach in which atom interferometry is performed in a laboratory-scale Einstein Elevator. With a total interrogation time of $2T = 200$ ms, we demonstrate an acceleration sensitivity of $6 times 10-7$ m/s$2$ per shot. These represent state-of-the-art results achieved in microgravity and further demonstrates the potential of quantum inertial sensors in Space.

• Combined Classical and Quantum Accelerometers For the Next Generation of Satellite Gravity Missions [0.0]
  Quantum accelerometers are very promising for future satellite gravity missions. Their limitations due to the low measurement rate and the existence of ambiguities in the raw sensor measurements call for hybridization of the quantum accelerometer with a classical one. We performed a more advanced hybridization simulation by implementing a comprehensive noise model for the satellite-based quantum accelerometers. We found that implementing a hybrid accelerometer onboard a future gravity mission improves the gravity solution by one to two orders in lower and higher degrees.

We infer a precision enhancement of 8.8 decibels when measuring a small difference between external fields. We estimate that tens of decibels of precision enhancement could be attained for measurements with a higher atom flux.

  NASA's Cold Atom Lab operates onboard the International Space Station as a multi-user facility for studies of ultracold atoms. Atom interferometers are a class of quantum sensors which can use freely falling gases of atoms cooled to sub-photon-recoil temperatures. A three-pulse Mach-Zehnder interferometer was studied to understand limitations from the influence of ISS vibrations. Ramsey shear-wave interferometry was used to manifest interference patterns in a single run that were observable for over 150 ms free-expansion time.

Thanks to a set of domain randomizations simulating uncertainties in physical measurements, the agent successfully aligns this interferometer without any fine tuning.
