QSolid and QuBRA – newly funded BMBF projects with ML4Q members

QSolid and QuBRA – newly funded BMBF projects with ML4Q members

by Marian Barsoum | Jan 12, 2022 | 2022, News, Press release, Transfer

Two consortial projects which involve ML4Q members started as of January 1st within the Federal Government Framework Program “Quantum technologies – from basic research to market”. Quantum computer in the solid state – QSolid was granted a...
New paper in Science – A new phase transition in the Bose-Einstein condensate now observed

New paper in Science – A new phase transition in the Bose-Einstein condensate now observed

by Marian Barsoum | Apr 14, 2021 | 2021, Articles, BEC related, Press release

ML4Q researchers from the groups of Martin Weitz and Johann Kroha in Bonn have published a Science paper on their new observation of a new phase transition of a photon Bose-Einstein condensate. 10 years after discovering the Bose-Einstein condensate, the researchers...
Köhl group realizes quantum network node

Köhl group realizes quantum network node

by Marian Barsoum | Mar 15, 2021 | 2021, Articles, Press release

The group of Michael Köhl succeeded in implementing a special interface between light and matter. In npj Quantum Information they report the realization of a quantum network node using a trapped ion inside a fiber-based Fabry–Perot cavity. They show the generation of...
A new superconducting circuit could accelerate the realization of a fault-tolerant quantum computer

A new superconducting circuit could accelerate the realization of a fault-tolerant quantum computer

by Marian Barsoum | Feb 18, 2021 | 2021, Articles, Press release

New theoretical work from the group of David DiVincenzo proposes a scheme to circumvent the necessity of active qubit stabilization and enable highly efficient hardware for future large-scale quantum processors. Congratulations to the authors! Together with colleagues...
Compact, stable and color-tunable – news from the ML4Q Fiber Lab

Compact, stable and color-tunable – news from the ML4Q Fiber Lab

by Marian Barsoum | Jan 21, 2021 | 2021, Articles, Press release

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...
