The superradiant phase transition (SPT) has been widely studied in cavity quantum
electrodynamics (CQED). However, this SPT is still subject to ongoing debates due to the no …

We show how to enhance the detection sensitivity of magnon Kerr nonlinearity (MKN) in
cavity magnonics. The considered cavity-magnon system consists of a three-dimensional …

Strong long-distance spin-magnon coupling is essential for solid-state quantum information
processing and single-qubit manipulation. Here, we propose an approach to realize strong …

We show how to generate Bell states and N-partite W states of long-distance
superconducting (SC) qubits in a SC waveguide QED system, where SC qubits are coupled …

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 …

We consider the problem of engineering the two-excitation Dicke state| D 2 3〉 in a three-
qubit system with all-to-all Ising-type qubit-qubit interaction, which is also subject to global …

Motivated by the significantly improved scalability of optically trapped neutral-atom systems,
extensive efforts have been devoted in recent years to quantum-state engineering in …

We investigate a time-efficient and robust preparation of spin-squeezed states—a class of
states of interest for quantum enhanced metrology—in internal bosonic Josephson junctions …

The twist-and-turn dynamics of spin squeezing results from the interplay of the one-axis-
twisting (nonlinear in the collective-spin operators) and the transverse-field turning (linear) …

Nonreciprocal devices, allowing to manipulate one‐way signals, are crucial to quantum
information processing and quantum networks. Here a nonlinear cavity‐magnon system is …
