Quantum sensing of antiferromagnetic magnon two-mode squeezed vacuum

ALE Römling, A Kamra - Physical Review B, 2024 - APS
Néel ordered antiferromagnets exhibit two-mode squeezing such that their ground state is a
nonclassical superposition of magnon Fock states. Here we theoretically demonstrate that …

Inductive magnon noise spectroscopy

L Siegl, R Schlitz, JB Youssef, C Runge… - arXiv preprint arXiv …, 2024 - arxiv.org
State tomography allows to characterize quantum states, and was recently applied to reveal

Dipole-dipole-interaction-induced entanglement between two-dimensional ferromagnets

D Wuhrer, N Rohling, W Belzig - arXiv preprint arXiv:2403.13354, 2024 - arxiv.org
We investigate the viability of dipole-dipole interaction as a means of entangling two distant
ferromagnets. To this end we make use of the Bogoliubov transformation as a symplectic …
