Optimal control of pulses for atom interferometry

The application of optimal control techniques to the manipulation of quantum systems is a mature field of study in the realm of NMR spectroscopy. Its application to atom interferometry, however, is a relatively new endeavour. In this seminar I will present some of my work in this field, both in academia and industry. Specifically, I will describe the design and implementation of modulated laser pulses to improve the performance of atom interferometric inertial sensors. I will touch upon both design considerations : moving beyond heuristics inherited from NMR literature to develop figures of merit specific to cold-atom sensors ; and the specifics of implementation : discussing the characterisation of individual pulse performance, the calibration of experimental hardware, and the demonstration of real sensitivity enhancements in a simulated noisy environment.
While of particular interest to experts in quantum sensing and atom interferometry, this presentation will be light on equations and employ a pedagogical approach suited to a general technical audience.
