Deterministic quantum entanglement between macroscopic ferrite samples

JMP Nair, GS Agarwal - Applied Physics Letters, 2020 - pubs.aip.org
We show how macroscopic magnetic samples like yttrium iron garnet samples are excellent
candidates for producing deterministic quantum entanglement and, thus, providing a …

Tuning entanglement by squeezing magnons in anisotropic magnets

J Zou, SK Kim, Y Tserkovnyak - Physical Review B, 2020 - APS
We theoretically study the entanglement between two arbitrary spins in a magnetic material
where magnons naturally form a general squeezed coherent state in the presence of an …

Macroscopic entanglement of two magnon modes via quantum correlated microwave fields

M Yu, SY Zhu, J Li - Journal of Physics B: Atomic, Molecular and …, 2020 - iopscience.iop.org
We present a scheme to entangle two magnon modes in two macroscopic yttrium-iron-
garnet spheres. The two spheres are placed inside two microwave cavities, which are driven …

Magnon-magnon entanglement and its quantification via a microwave cavity

V Azimi Mousolou, Y Liu, A Bergman, A Delin… - Physical Review B, 2021 - APS
Quantum magnonics is an emerging research field, with great potential for applications in
magnon based hybrid systems and quantum information processing. Quantum correlation …

Magnon-atom interaction via dispersive cavities: Magnon entanglement

D Kong, X Hu, L Hu, J Xu - Physical Review B, 2021 - APS
In general, a magnon does not interact directly with an atom. Here we present a scheme to
generate coherent coupling between two magnons and a superconducting artificial atom via …

Nonlocal magnon entanglement generation in coupled hybrid cavity systems

DW Luo, XF Qian, T Yu - Optics Letters, 2021 - opg.optica.org
We investigate dynamical generation of macroscopic nonlocal entanglements between two
remote massive magnon–superconducting-circuit hybrid systems. Two fiber-coupled …

Quantum entanglement between two magnon modes via Kerr nonlinearity driven far from equilibrium

Z Zhang, MO Scully, GS Agarwal - Physical Review Research, 2019 - APS
We propose a scheme to entangle two magnon modes via the Kerr nonlinear effect when
driving the systems far from equilibrium. We consider two macroscopic yttrium iron garnets …

Quantum correlation in disordered spin systems: Applications to magnetic sensing

P Cappellaro, MD Lukin - Physical Review A—Atomic, Molecular, and Optical …, 2009 - APS
We propose a strategy to generate a many-body entangled state in a collection of randomly
placed, dipolarly coupled electronic spins in the solid state. By using coherent control to …

Heralded entanglement between widely separated atoms

J Hofmann, M Krug, N Ortegel, L Gérard, M Weber… - Science, 2012 - science.org
Entanglement is the essential feature of quantum mechanics. Notably, observers of two or
more entangled particles will find correlations in their measurement results that cannot be …

Entangling a magnon and an atomic ensemble mediated by an optical cavity

Y Wu, JH Liu, YF Yu, ZM Zhang, JD Wang - Physical Review Applied, 2023 - APS
We propose a scheme to entangle a magnon in an yttrium iron garnet sphere with an atomic
ensemble by using an optical cavity as the qubus. The cavity mode couples with the magnon …
