… we have studied remote entanglement generation of macroscopic magnons and SQs in two
coupled hybrid microwave cavity systems. The communication channel of the two cavities is …

… where we consider only qubit or magnon mode j coupled to the cavity array. x = 0, −l, l
represents the position for the qubit, magnon mode 1, and magnon mode 2. Solving these …

… The magnon-magnon entanglement can be realized not only in ferrimagnets but also in
an … enhancement of magnon-magnon entanglement in an antiferromagnet via the cavity-induced …

… We now proceed to explain the enhancement of the magnon-magnon entanglement in
the presence of the light mode. In terms of the two-mode squeezing operator S(θ) = …

… For the remote entanglement generation, we consider two cavity-magnon systems that are
coupled to each other through an optical fiber. It is known that the magnon modes operate …

… magnon even or odd cat states by performing local non-Gaussian operations on the optical
mode that is entangled with the magnon mode … magnon cat states is expected to be t ∼ 1 μs. …

… the tripartite entanglement where magnons, cavity photons, and phonons are entangled with
… further prove that the steady state of the system is a genuinely tripartite entangled state. The …

… magnon entanglement entropy allows for experimental quantification of magnon-magnon
entanglement, as … has been used for verification of entanglement in optical and atomic systems …

… entanglement transfer among the six bipartite entanglements. Then we focus on entanglement
between a magnon and an atomic ensemble, and we show that the entanglement can be …

… The condition for optimizing the magnonmagnon entanglement is found … magnonmagnon
entanglement can be created. Such entanglement is also shown to be robust against cavity …
