- Abstract summary: Magnetic invisible magnon modes, their chiralities and quantum properties can be characterized through the Rabi frequency of the superconducting transmon qubit.
We demonstrate how magnetically invisible magnon modes, their chiralities and quantum properties such as nonlocality and two-mode magnon entanglement in bipartite AFMs can be characterized.

- Abstract: The detection of magnons and their quantum properties, especially in
antiferromagnetic (AFM) materials, is a substantial step to realize many
ambitious advances in the study of nanomagnetism and the development of energy
efficient quantum technologies. The recent development of hybrid systems based
on superconducting circuits provides the possibility of engineering quantum
sensors that exploit different degrees of freedom. Here, we examine the
magnon-photon-transmon hybridisation based on bipartite AFM materials, which
gives rise to an effective coupling between a transmon qubit and magnons in a
bipartite AFM. We demonstrate how magnetically invisible magnon modes, their
chiralities and quantum properties such as nonlocality and two-mode magnon
entanglement in bipartite AFMs can be characterized through the Rabi frequency
of the superconducting transmon qubit.
