The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices ...

Optical clocks are typically evaluated on two levels — accuracy (how close a clock comes to measuring the ideal “true” time, ...

Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with relative uncertainties as low as one part in 10²⁰.

Optical clocks can reach accuracies at the level of 10-18 , “which is a number so accurate that if the clock started running at the big bang, by now it will have lost 1 second”, says Alexandra ...

RF clock performance: (a) The fractional Allan deviation of the clock without (orange) and with (green and purple) noise suppression, the extracted interferometric noise (yellow), and the optical ...

Optical clocks are incredibly precise, but they are also highly complex. There are just around 100 of them in existence worldwide, largely because they are difficult to build, operate, and ...

The rapid evolution of quantum computing and optical clocks has led to a demand for an unprecedented degree of stability, thereby driving the boundaries of contemporary laser technology. Toptica’s CLS ...
