Over the past two decades, important progress in cold atom physics has established cold-atom interferometry as a unique tool for precision measurements of time and frequency and for inertial sensing. As a PhD student, I worked on a cold-atom gyroscope at SYRTE , l’Observatoire de Paris which pushes the performance of a Cs cold-atom interferometer on the ground which is sensitive principally to rate of rotation in a particular axis where we reached a sensitivity of 1 nrad/s in 1000 s of integration [1]. Presently, at Imperial College London, I am a researcher at Imperial College London, where we are working on a compact 1-axis cold-atom accelerometer using Rb atoms, which will combine the large operating range of a high bandwidth MEMS accelerometer with the high sensitivity of the cold-atom accelerometer. The purpose is to push the performance of such cold-atom inertial sensors such that they will set a baseline for very precise inertial sensing and, in the future, be used for navigational purposes.
