In Optics Express, scientists led by Dieter Meschede report on building optical fiber filters that are not only extremely compact and stable, but also color-tunable. Optical resonators or filters are important components cutting out very narrow spectral lines from...

Building on the added value of having a multi-site cluster, the idea of creating a hub for available infrastructure within our ML4Q framework emerged and a first fabrication map for the Aachen site was posted last November. Here, we present an overview of fabrication...

ML4Q researchers from Bonn have published a Nature paper on competing magnetic orders in a bilayer Hubbard model with ultracold atoms - congratulations to all the authors on their impressive results! Details can be found in the press release. Publication: Marcell...

Three cluster members joined efforts to discuss chaotic fluctuations in superconducting transmons. In their recent paper (https://arxiv.org/abs/2012.05923), the authors from the groups of Simon Trebst, Alexander Altland and David DiVincenzo investigate the possibility...

​More that 120 cluster members and associated members joined in the first talk of the newly launched ML4Q Concepts seminar series. The first talk was given by Fabian Hassler who gave an introduction of Majorana fermions and their application potential in quantum...
