High BandwidthInterial Atom Source (high-BIAS)

Lead Participant: Airbus Group Limited


Our work focuses on the development of a compact, integrated, high bandwidth source of cold atoms. This will provide a key subsystem for many quantum technologies and will be initially targeted for inertial sensors, such as accelerometers, gyroscopes, and full inertial measurement units (IMUs) based on atom interferometry. In order to transition these systems out of the laboratory and into commercial applications this work will address the present challenges of size, weight, and power (SWaP) and measurement rate. Through innovative engineering coupling a compact ultra-high vacuum system to a compact lasers source, we will produce a low SWaP system suitable for aerospace use. In addition, by using sequential cold matter generation and progressive cooling to maximize the flux of cold atoms, the system will maximize potential sensor bandwidth. This system will demonstrate conclusively that the SWaP and bandwidth are not fundamental limitations to cold atom inertial sensing for aerospace applications. The project will generates technology for the end user and enables a market for component makes, subsystem suppliers, and system integrators providing both market pull and technology push.
