Superconducting Qubits Coupled to Propagating Magnons

ORAL

Abstract

Over the last few years, there has been significant experimental effort in coupling superconducting qubits to magnons. In most of those experiments, the coupling was between magnetostatic modes in an Yttrium Iron Garnet (YIG) sphere and a superconducting qubit, mediated via a 3D cavity [1]. Using propagating magnons instead of microwave photons to relay information and mediate interactions between qubits opens up a range of new experiments due to the different properties propagating magnons have compared to microwave photons [2]. Here, we focus on coupling superconducting qubits to propagating magnons in a YIG film.
