Tuning entanglement by squeezing magnons in anisotropic magnets

Abstract

There has been much recent interest in coherently preparing and manipulating entanglement in various systems, stimulated by its importance in quantum information science. Here, the authors discuss entanglement between individual spins within anisotropic magnets in thermodynamic equilibrium, suggesting magnetic materials as a natural resource for processing quantum information. Furthermore, they show that entanglement can jump discontinuously by varying an applied magnetic field, which can potentially serve as a switch for quantum information processing tasks.
