The goal of project ICAS is the integration of ultra cold atom based sensor principles on the CMOS platform. Modern techniques in atomic physics allow to cool down atomic ensembles close to absolute zero temperature (e.g. down to a few 10 nano Kelvin). These so called "ultra-cold atoms" are an extremely suitable candidate for the realisation of highly sensitive quantum based sensing devices., as their beheauviour is susceptibel to external influence such as gravity or magneitc fields. Within the Project ICAS we try together with partners at the University of Nottingham to integrate cold atoms on a CMOS compatible platform, which is the first step towards mass production of these sensor systems.
