An Al clock with systematic uncertainty and its frequency ratios

Fabian Dawel, Johannes Kramer, Derwell Drapier +15

Advances in optical clocks motivate a redefinition of the second, requiring rigorous evaluations of systematic uncertainties and robust consistency among the clocks. Here, we repor…

A high-stability optical clock based on a continuously ground-state cooled Al ion without compromising its accuracy

Fabian Dawel, Lennart Pelzer, Kai Dietze +12

Single ion optical clocks have shown systematic frequency uncertainties below , but typically require more than one week of averaging to achieve a corresponding statistic…

Entanglement-enhanced optical ion clock

Kai Dietze, Lennart Pelzer, Ludwig Krinner +11

Entangled states hold the promise of improving the precision and accuracy of quantum sensors. We experimentally demonstrate that spectroscopy of an optical clock transition using e…

Multi-ion frequency reference using dynamical decoupling

Lennart Pelzer, Kai Dietze, Víctor J. Martínez-Lahuerta +6

We present the experimental realization of a continuous dynamical decoupling scheme which suppresses leading frequency shifts in a multi-ion frequency reference based on $^{40}\mat…

Coherent photo-thermal noise cancellation in a dual-wavelength optical cavity for narrow-linewidth laser frequency stabilisation

Fabian Dawel, Alexander Wilzewski, Sofia Herbers +7

Optical resonators are used for the realisation of ultra-stable frequency lasers. The use of high reflectivity multi-band coatings allows the frequency locking of several lasers of…

A low phase noise cavity transmission self-injection locked laser system for atomic physics experiments

Ludwig Krinner, Kai Dietze, Lennart Pelzer +2

Lasers with high spectral purity are indispensable for optical clocks and coherent manipulation of atomic and molecular qubits for applications such as quantum computing and quantu…
