A Josephson current through a half-metallic ferromagnet between two conventional
superconductors is theoretically studied. The spin dynamics such as magnon excitation …

We propose a theoretical scheme of using two fixed-frequency resonator couplers to tune
the interaction between two Xmon qubits. The indirect interaction between two qubits …

Coherent coupling between spin-wave excitations (magnons) and microwave photons in a
cavity may disclose new paths to unconventional phenomena as well as novel applications …

We investigate magnon statistics in a qubit-magnon hybrid quantum system in which an
effective appreciable qubit-magnon coupling can be realized by exchanging virtual cavity …

Rigidity of an ordered phase in condensed matter results in collective excitation modes
spatially extending to macroscopic dimensions. A magnon is a quantum of such collective …

We report the observation of strong coupling between the exchange-coupled spins in a
gallium-doped yttrium iron garnet and a superconducting coplanar microwave resonator …

Generation of entanglement between spatially separated macroscopic systems enables
quantum networks and fundamental tests of quantum theory. Here, we propose a scheme to …

We perform Eliashberg calculations for magnon-mediated superconductivity in a normal
metal, where the electron-magnon interaction arises from interfacial coupling to …

We propose a scheme for preparing magnon squeezed states in a hybrid cavity-magnon-
qubit system. The system consists of a microwave cavity that simultaneously couples to a …

Spin qubits in semiconductors are a promising platform for producing highly scalable
quantum computing devices. However, it is difficult to realize multiqubit interactions over …
