USOQS Q-CLOCKS CC4C Workshop


October 5th, 2020 Ultra-stable optical oscillators from quantum coherent and entangled systems.


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.

The overall objective of this project is to realise a new generation of ultra-stable optical oscillators which take advantage of quantum technologies. Knowledge transfer in theoretical and experimental quantum manipulation from quantum optics and quantum computing, to the optical frequency metrology field is at the heart of the project.

The implementation, study and characterisation of both established and brand-new methods to develop quantum-enhanced optical oscillators toward a 10-17 relative instability at one second integration time is targeted. This will enable the operation of optical clocks and atomic sensors at their projected accuracy limits of 10-18 with practical measurement times ranging from minutes to hours. Non-classical techniques will be introduced to overcome technical obstacles and the Quantum projection noise (QPN) limit, to approach the Heisenberg noise limit.
