Optical atomic clocks are considered the atomic clocks of the future because they are more accurate than microwave atomic clocks. These clocks are usually complex laboratory setups. However, the transportable optical strontium lattice clock developed by the Physikalisch-Technische Bundesanstalt (PTB) can be transported to its place of use by trailer and still ranks among the top optical clocks. PTB researchers report on the results of the comprehensive characterisation of this clock, which has now been completed, in the latest issue of the journal ‘Quantum Science and Technology’.
