The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

A two-interacting-qubit quantum Rabi-like model with vanishing transverse fields on the
qubit pair is studied. Independently of the coupling regime, this model can be exactly and …

Confined electromagnetic modes strongly couple to collective excitations in ensembles of
quantum emitters, producing light–matter hybrid states known as polaritons. Under such …

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 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 …

Interconversions of W and Greenberger-Horne-Zeilinger states in various physical systems
have recently been attracting considerable attention. We address this problem in the fairly …

Using the quantum-brachistochrone formalism, we address the problem of finding the fastest
possible (time-optimal) deterministic conversion between W and Greenberger-Horne …

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) …
