Optical clocks require more stable optical oscillators to accelerate the redefinition of the SI second, bring excellent fundamental science to metrology and enable applications for innovative sensors in clock-based geodesy.
While the application of quantum measurement strategies in atomic clocks and sensors via multi-particle and light-matter interactions is at the proof-of-principle stage, this project will implement and further develop state-of-the-art quantum measurement strategies on optical oscillators of metrological relevance. It will impact on metrology and sensing with cold atomic systems and optical devices, as well as in those techniques used in scalable quantum information processing and simulation.
