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

Spins in solids or in molecules possess discrete energy levels, and the associated quantum
states can be tuned and coherently manipulated by means of external electromagnetic …

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

Magnon-photon coupling inside a cavity has been experimentally realized and has attracted
significant attention for its potential docking with quantum information science. Whether this …

We review the progress made in integrating magnetic molecules containing transition metal
ions into nanoelectronic solid-state devices and using them as molecular spin qubits …

Molecular nanomagnets (MNMs), molecules containing interacting spins, have been a
playground for quantum mechanics. They are characterized by many accessible low-energy …

We discuss the problem of gauge fixing for strongly correlated electrons coupled to quantum
light, described by projected low-energy models such as those obtained within tight-binding …

Molecular spin qubits have been shown to reach sufficiently long quantum coherence times
to envision their use as hardware in quantum processors. These will however require their …

Vanadyl systems have been shown to possess superior quantum coherence among
molecular spin qubits. Meanwhile two-dimensional (2D) networks of spin qubit nodes could …

A stable and high-quality single-magnon state is desired by the single-magnon source for
quantum-information application with a macroscopic spin system. We consider a hybrid …
