Circuit Quantum ElectroMagnonics for Scalable Quantum Computing

Quantum computing can solve problems beyond classical reach, but scaling hardware remains a challenge. This project targets a critical bottleneck: the cryogenic microwave infrastructure for scalable quantum computing. It introduces fully integrated hybrid quantum systems combining microwave photons, magnons, and Josephson effects, pioneering the new field of Circuit Quantum ElectroMagnonics. Three directions will be pursued: novel superconducting 3D-integrated architectures for strong magnon–photon coupling, directional quantum interfaces for networking, and quantum-limited amplifiers for qubit readout. The PI brings rare interdisciplinary expertise and proven leadership, fostering an inclusive and strategic research environment. Hosted at the Niels Bohr Institute and supported by the Villum Young Investigator Programme, this project will drive breakthroughs in quantum hardware, establish the PI as a globally recognized scholar, and enhance Denmark’s leadership in the field.
