ERC Starting Grant for Julian Schmitt

We congratulate ML4Q project PI Julian Schmitt on receiving an ERC Starting Grant! In his project TopoGrand, Julian will investigate new ways of generating and controlling topological states in open systems by using Bose-Einstein condensates of photons in coupled...

Spinning out of Science – A personal view on technology transfer and starting your own business

The great thing is that our technology works simultaneously in research and in practice. Any progress we make in development is directly used for basic research in the laboratory next door.We did it! A few weeks ago, we officially established Midel Photonics GmbH – a...

Error-Free Quantum Computing gets real – Fundamental building blocks for fault-tolerant quantum computing demonstrated

Error-free quantum computing gets real Fundamental building blocks for fault-tolerant quantum computing demonstrated   For quantum computers to be useful in practice, errors must be detected and corrected. A research group at RWTH Aachen University, in...


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.
