The Quantum Valley Lower Saxony has received spectacular attention from the press and from Lower Saxonys Minister of Science and Culture Björn Thümler. Reports were made from, amongst others NDR and Sat-1. Online articles can be found from (amongst others) Zeit, Welt, Süddeutsche Zeitung, Stern, and...

Trapped ions are excellent systems for optical frequency metrology, as they can be well isolated from the external environment. Using laser-cooling, ion temperatures below the millikelvin level can be reached, thereby greatly suppressing the relativistic time dilation associated with the thermal...

Electric field noise is a major contributor to the motional heating of trapped ions, resulting in frequency shifts and significant frequency uncertainties in precision spectroscopy, as well as decoherence in quantum simulation. This  becomes even more relevant when extending the systems to 2D or 3D...

Atomic clocks operate at extraordinary levels of precision and accuracy, and can be used for searches for new physics beyond the Standard Model of particle physics (SM) by searching for miniscule deviations in their operating frequencies. For example, a hypothetical fifth force between the neutrons...
