Asymmetric EPR Steering in a Cavity-Magnon System Generated by a Squeezed Vacuum Field and an Optical Parametric Amplifier

A Hidki, N Benrass, A Lakhfif, M Nassik - arXiv preprint arXiv:2408.05638, 2024 - arxiv.org
We investigate a cavity-magnon system with two magnon modes coupled to a common
cavity microwave field. The cavity is integrated with an optical parametric amplifier (OPA) …

Stationary Quantum Entanglement and Asymmetric Steering in Cavity Magnonic System with Floquet Field and Coherent Feedback

SY Guan, HF Wang, X Yi - Advanced Quantum Technologies - Wiley Online Library
A scheme is proposed to prepare quantum entanglement and quantum steering between
two indirectly coupled microwave cavity modes within a hybrid cavity magnonic system. The …
