Abstract
Optical atomic clocks are the most precise and accurate measurement devices, reaching fractional systematic uncertainties below one part in 10-18. Their exceptional performance opens up a wide range of applications in fundamental science and technology. The extreme electronic properties of highly charged ions (HCI) make them highly sensitive probes for tests of fundamental physical theories and significantly lower sensitivity to some of the leading systematic perturbations that affect state-of-the-art optical clocks. This makes them exciting candidates for next-generation clocks. In this contribution, we will briefly review the history of optical spectroscopy of HCI and how scientific advances enabled the first coherent spectroscopy of HCI using quantum logic techniques. A first generation of optical clocks based on HCI with atom-related systematic uncertainties at the 10-18 level and below is demonstrated. Comparisons of the isotope shift between 40Ar13+ and 36Ar13+ as well as g-factor measurements with theory are interpreted as a test of quantum electrodynamic (QED) theory. This demonstrates the suitability of HCI as references for high-accuracy optical clocks and to probe for physics beyond the standard model.
