Magnetic Nanocomponents for Frequency Converting in Quantum Computing Technologies

Abstract

This manuscript presents the features of the application of thin-film YIG magnets (micro- and nanoscaled) in the development of effective quantum converters of electromagnetic radiation from the microwave band to the optical. The manuscript analyzes studies of thin-film YIG magnets that are placed in a specially selected region of a planar microwave resonator in order to maximize their strong electromagnetic coupling. Key parameters of such a resonator system, namely, the strength of the photon-magnon coupling and the cooperativity are analyzed. Promising planar microwave resonators with YIG film, in which strong photon-magnon coupling is realized, are considered. © 2024 Elsevier B.V., All rights reserved.
