Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

Magnonics addresses the physical properties of spin waves and utilizes them for data
processing. Scalability down to atomic dimensions, operation in the GHz-to-THz frequency …

Nonclassical quantum states are the pivotal features of a quantum system that differs from its
classical counterpart. However, the generation and coherent control of quantum states in a …

The magnon cat state represents a macroscopic quantum superposition of collective
magnetic excitations of large number spins that not only provides fundamental tests of …

Chirality or handedness distinguishes an object from its mirror images, such as the spread
thumb, index finger, and middle finger of the right and left hand. In mathematics, it is …

We study nonreciprocal photon blockade in cavity optomagnonics, where a sphere of
ferromagnetic crystal supports two optical whispering-gallery modes and one magnon …

We propose to directly and quantum-coherently couple a superconducting transmon qubit to
magnons—the quanta of the collective spin excitations, in a nearby magnetic particle. The …

Nonlinear magnonics studies the nonlinear interaction between magnons and other
physical platforms (phonon, photon, qubit, spin texture) to generate novel magnon states for …

In this paper, we propose a quantum interference mediated control of switching between
magnon-atom entanglement and magnon blockade. A three-level Λ configuration atomic …
