Magnon Bundle in a Strongly Dissipative Magnet

Abstract

The rise of quantum information science based on hybrid quantum systems bridges different areas of research and provides innovative perspectives on quantum technology. Magnons show great potential as information carriers, but generating robust quantum states of magnons in a scalable hybrid system remains an outstanding challenge. Here the authors consider a superconducting qubit coupled to magnets by the dipole interaction. With delicate frequency detuning between magnet and qubit, an exotic quantum state of magnons is found. Interestingly, magnetic dissipation helps to stabilize the quantum states, which readily involves a wide class of magnetic materials in quantum information.
