In a paper published today we present a novel ion trap fabrication method enabling the realization of multilayer ion traps scalable to an in principle arbitrary number of metal-dielectric levels.

We benchmarked our method by fabricating a multilayer ion trap with integrated three-dimensional...

We developed an ultra-stable laser system at 946 nm for the interrogation of our multi-ion clock based on Indium ions. The demonstrated instability of 1.1x10-16 at 1 s ranks among the best instabilities achieved worldwide with ultra-stable lasers at room temperature. In addition, all key components...

In our latest paper we demonstrated quantum control of 9Be+ ions directly implemented by an optical frequency comb.

Based on numerical simulations of the relevant processes in 9Be+ for different magnetic field regimes, we demonstrated a wide applicability when controlling the comb’s spectral...
