New WSS research center for molecular quantum systems

The University of Basel and the University of Bern are launching a new research center dedicated to the development of superconducting quantum units. The Werner Siemens Foundation is supporting the initiative with CHF 15 million over the next eleven years.

The WSS Research Center for Molecular Quantum Systems will explore an innovative approach to quantum computing by leveraging superconducting materials and topological quantum bits (qubits). These specialized qubits, which store and process information according to the principles of quantum mechanics, are known for their robustness against interference—an essential characteristic for reliable quantum computation.

A key focus of the center is the use of superconducting materials, which allow electricity to flow without resistance, minimizing energy loss. By integrating these materials with molecular structures, researchers aim to develop more stable and efficient qubits than current technologies permit. The concept of topological protection—where the qubits’ structure inherently shields them from external disturbances—plays a crucial role in maintaining computational accuracy over extended operations.

“Our aim is to realize superconducting qubits using topological superconductors for the first time,” explained Professor Ernst Meyer, Director of the WSS Research Center and Professor of Physics at the University of Basel. “We are not simply refining existing technology but taking a fundamentally new approach that combines physics, chemistry, and interdisciplinary research.”

The research center will synthesize molecules with precise properties designed to coat superconductors and facilitate qubit formation. Through electromagnetic field manipulation, these qubits will interact and execute logical operations. Additionally, experiments at extremely low temperatures will help researchers understand the molecular binding properties of superconductors, enhancing their stability.

Stable qubits for next-generation quantum computing

With a long-term vision of scaling quantum computing technology, the center aims to reduce computational errors and enable quantum processors at the nanometer scale. These advancements could support applications such as climate modeling, medical simulations, and energy-efficient information processing.

The project brings together expertise from the University of Basel, the University of Bern, and the University of Salzburg. It will be led by Professors Ernst Meyer (Director) and Dominik Zumbühl (Co-Director), strengthening Switzerland’s position in cutting-edge quantum research.
