Cooperative-effect-induced one-way steering in open cavity magnonics

Researchers demonstrated a novel method to generate and control one-way quantum steering between photon and magnon modes in a non-Hermitian cavity magnonic system by leveraging the cooperative effects of coherent and dissipative coupling, achieving robust quantum correlations that can be precisely controlled through the relative phase of cooperative dissipation and magnon mode frequency detuning.
