A Department of Energy-funded project between Argonne and the University of Illinois Urbana-Champaign explores coupling magnetism and microwaves for quantum discoveries.

The U.S. Department of Energy (DOE) has recently funded both DOE’s Argonne National Laboratory and the University of Illinois Champaign-Urbana (UIUC) in a new project related to quantum information science. The Argonne team will bring to the project its expertise in coupling superconducting and magnetic systems. The UIUC team will contribute its world-class capabilities for developing new magnetic materials for quantum systems.

“Quantum information science promises new and different ways in which scientists can process and manipulate information for sensing, data transfer, and computing,” said Valentine Novosad, a senior scientist in Argonne’s Materials Science division. “UIUC is a perfect partner for us to realize breakthrough discoveries in this area.”

In the emerging field of quantum information science, microwaves may play a fundamental role because their physical properties enable them to provide desired quantum functionality at temperatures near to
