New video on Quantum Cryptography

Can you explain what you are doing in your PhD and postdoctoral studies in different levels of difficulty? Are you able to take your audience step by step into the details of your complicated thesis work? Here is how we challenged our researchers! In our video series...

Physics is not only a “boy thing” – an interview with Corinna Kollath

Corinna, it's almost 10 years now that you became professor for Theoretical Quantum Physics at the University of Bonn. How has it been? I hardly notice that it is almost 10 years, since it has been very busy: I contributed to setup two collaborative research centers...

MINT Fans und Teens aufgepasst! Hast Du schon mal was von Quantencomputern gehört? Vielleicht bist Du auch schon einigen verrückten Phänomenen der Quantenphysik im Unterricht begegnet? Oder auch noch nicht? Am Quanteen Day 2023 wollen wir uns der Faszination...

Schreiber and Bluhm group demonstrate electron transport on a quantum chip

Lars Schreiber and Hendrik Bluhm have now come a significant step closer to solve qubit connectivity on semiconductor chips. Their team succeeded in transferring electrons, the carriers of quantum information, over several micrometres on a quantum chip. Their "quantum...

ML4Q member, Sebastian Hofferberth, has received an ERC Synergy Grant together with colleagues from Humboldt University Berlin (Arno Rauschenbeutel) and Aarhus University (Thomas Pohl). The "SuperWave" project, led by Humboldt University Berlin, deals with the...


About ML4Q

“Matter and Light for Quantum Computing” (ML4Q) is a Cluster of Excellence funded in 2019 within the Excellence Strategy by the German Research Foundation (DFG). It is a cooperation by the universities of Cologne, Aachen, and Bonn, as well as the Forschungszentrum Jülich.

ML4Q at a glance (download link)


The aim of ML4Q is to develop new computing and networking architectures using the principles of quantum mechanics. Computing and networking power beyond anything classically imaginable would make quantum computers powerful tools in key areas such as materials design, pharmaceutics, or artificial intelligence. Quantum communication could be made effectively secure.
ML4Q builds on and extends the complementary expertise in the three key research fields (solid-state physics, quantum optics, and quantum information science) at the partner institutions in order to develop the best hardware platform for quantum information technology, and provide comprehensive blueprints for a functional quantum information network.
