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…
A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions
Tobias Leopold, Steven A. King, Peter Micke +5
A cryogenic radio-frequency ion trap system designed for quantum logic spectroscopy of highly charged ions is presented. It includes a segmented linear Paul trap, an in-vacuum imag…
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…
Detection of motional ground state population of a trapped ion using delayed pulses
Florian Gebert, Yong Wan, Fabian Wolf +2
Efficient preparation and detection of the motional state of trapped ions is important in many experiments ranging from quantum computation to precision spectroscopy. We investigat…
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…
