Landé factor measurement of Ti using simultaneous co-magnetometry and quantum logic spectroscopy
Till Rehmert, Maximilian J. Zawierucha, Kai Dietze +6
The use of atomic systems as accurate magnetic field probes requires precise characterization of the particle's magnetic properties. Insufficient knowledge of the spatial and tempo…
Quantum logic control of a transition metal ion
Till Rehmert, Maximilian J. Zawierucha, Kai Dietze +2
Extending quantum control to increasingly complex systems is crucial for both advancing quantum technologies and fundamental physics. In trapped ion systems, quantum logic techniqu…
Deterministic preparation of a dual-species two-ion crystal
Maximilian J. Zawierucha, Till Rehmert, Jonas Keller +3
The demand for efficient preparation methods for dual-species ion crystals is rapidly expanding across quantum technology and fundamental physics applications with trapped ions. We…
A scheme for quantum-logic based transfer of accuracy in polarizability measurement for trapped ions using a moving optical lattice
Fabian Wolf
Optical atomic clocks based on trapped ions suffer from systematic frequency shifts of the clock transition due to interaction with blackbody radiation from the environment. These…
Prospect for precision quantum logic spectroscopy of vibrational overtone transitions in molecular oxygen ions
Fabian Wolf, Jan C. Heip, Maximilian J. Zawierucha +3
Precision spectroscopy has been the driving force for progress of our physical understanding and still is a promising tool for the investigation of new physics. Molecules offer tra…
Motional Fock states for quantum-enhanced amplitude and phase measurements with trapped ions
Fabian Wolf, Chunyan Shi, Jan C. Heip +6
Non-vanishing fluctuations of the vacuum state are a salient feature of quantum theory. These fluctuations fundamentally limit the precision of quantum sensors. Nowadays, several s…
Unexpectedly large difference of the electron density at the nucleus in the 4p P fine-structure doublet of Ca
C. Shi, F. Gebert, C. Gorges +9
We measured the isotope shift in the S-P (D2) transition in singly-ionized calcium ions using photon recoil spectroscopy. The high accuracy of the technique…
Non-destructive state detection for quantum logic spectroscopy of molecular ions
Fabian Wolf, Yong Wan, Jan C. Heip +3
Laser spectroscopy of cold and trapped molecular ions is a powerful tool for fundamental physics, including the determination of fundamental constants, the laboratory test for thei…
Precision isotope shift measurements in Ca using highly sensitive detection schemes
Florian Gebert, Yong Wan, Fabian Wolf +3
We demonstrate an efficient high-precision optical spectroscopy technique for single trapped ions with non-closed transitions. In a double-shelving technique, the absorption of a s…
