Our new paper got published in njp Quantum Information.

We demonstrated the experimental realization of a two-qubit Mølmer–Sørensen gate on a magnetic field-insensitive hyperfine transition in 9Be+ ions using microwave near-fields emitted by a single microwave conductor embedded in a...

In our new article in Applied Physics B we present a multilayer surface electrode ion trap with embedded 3D microwave waveguide for the implementation of quantum logic entanglement gates.

We explain the simulation procedure that led to the trap design and characterization of the resulting microwave...

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...

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...

Today the BASE collaboration reports on the first measurement of cyclotron quantum heating rates in a cryogenic Penning trap. The team demonstrates that the scaled electric field noise in the spin-analysis trap, an essential instrument in the 1.5 p.p.b. measurement of the antiproton magnetic moment,...
