Overview

Novel scheme demonstrates robust magnon entanglement in ferrimagnetic crystals, highlighting implications for quantum technologies.

Key Points

  • The aim is to entangle two spatially separated ferrimagnetic YIG crystals using an optomagnonic ring cavity.
  • Injecting a laser field into an optomagnonic ring cavity.
  • Using magnetostriction-induced mechanical displacements coupled with an optical cavity via radiation pressure.
  • Driving magnons with electromagnetic fields while analyzing the robustness of entanglement.
  • Generated a robust macroscopic entangled state with red-detuned laser and blue-detuned microwave fields.
  • Magnon entanglement remains effective against thermal fluctuations.
  • Quantum steering is tuneable based on the asymmetry of magnomechanical coupling.
