Atomic clocks go nuclear

The quantum metrology research group is working towards a new type of atomic clock, that uses the atomic nucleus of Thorium-229 to realize the „ticking“. Going from electronic shell to nuclear transitions promises an increase in precision together with a more robust and compact implementation.
