Quantum one-way street in topological insulator nanowires

Quantum one-way street in topological insulator nanowires Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important...

Quantum Computing challenged by disorder – study published in Nature Communications

Research conducted in the ML4Q groups of Simon Trebst, Alex Altland and David DiVincenzo analyzed cutting edge device structures to demonstrate that some of them are indeed operating dangerously close to a threshold of chaotic meltdown. The challenge is to walk a thin...

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.
