Magnonics addresses the dynamic excitations of a magnetically ordered material. These
excitations, referred to as spin waves and their quanta, magnons, are a powerful tool for …

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

The emergent field of cavity quantum materials bridges collective many-body phenomena in
solid state platforms with strong light–matter coupling in cavity quantum electrodynamics …

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 …

Recent experiments have demonstrated that light and matter can mix together to an extreme
degree, and previously uncharted regimes of light-matter interactions are currently being …

Engineered quantum systems enabling novel capabilities for computation and sensing have
blossomed in the last decade. Architectures benefiting from combining complementary …

Hybrid dynamic systems have recently gained interest with respect to both fundamental
physics and device applications, particularly with their potential for coherent information …

We reveal the cooperative effect of coherent and dissipative magnon-photon couplings in an
open cavity magnonic system, which leads to nonreciprocity with a considerably large …

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

Photons at microwave and optical frequencies are principal carriers for quantum information.
While microwave photons can be effectively controlled at the local circuit level, optical …
