Ultra-stable optical oscillators from quantum coherent and entangled systems (USOQS)
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.
The overall objective of this project is to realise a new generation of ultra-stable optical oscillators which take advantage of quantum technologies. This implies a knowledge transfer in theoretical and experimental quantum manipulation from quantum optics and quantum computing, to the optical frequency metrology field.
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.
