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…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
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…
