An optical atomic clock for practical applications

PTB-News 1.2023

The aim in an international research project called AQuRA (Advanced Quantum Clock for Real-World Application) is to build an optical atomic clock that is based on neutral atoms and is both accurate and robust within 3.5 years. With this clock, using complicated laboratory setups or relying on atomic clock specialists will be a thing of the past for everyday practical applications, such as when geodata needs to be collected to measure sea level rise due to global warming. The EU is providing 7.5 million euros in funding for the project. Eight further partners from metrology institutes, universities and industry in six countries are also participating in the project in addition to PTB. The University of Amsterdam is tasked with coordination.
