Theoretical Nanoelectronics

The quantum mechanical nature of matter is the basis of all functioning of electronic devices. We use techniques from many-body physics, from quantum statistical physics, and from the mathematics of topology, to analyze the properties of electrons and other state-of-the-art physical platforms for quantum technology in a wide range of present-day exploratory devices. Our work can enable the development of new qubits, protocols for quantum error correction and quantum fault-tolerance, and new approaches to building scalable quantum computers.

Halfway Through: The QSolid Quantum Computer Project is Heading Towards the Prototype of the 10-Qubit Demonstrator

The QSolid project was launched in January 2022 with the aim of building a high-quality quantum computer "Made in Germany" based on superconducting quantum chips. After 30 months, the large-scale project, led by Prof. Frank Wilhelm-Mauch from Forschungszentrum Jülich, has reached the mid-term.

Quantum tug of war

A team of theoretical physicists led by Mohammad Ansari at FZJ, in collaboration with the experimental team of Britton Plourde at Syracuse University, introduced a novel approach using a multimode coupler that enables tunable coupling strength between any pair of qubits.
