• Abstract: We present a systematic study on the effects of dynamical transfer and steady-state synchronization of quantum states in a hybrid optomechanical network, consisting of two cavities with atoms inside and interacting via a common moving mirror (i.e. mechanical oscillator), are studied. It is found that high fidelity transfer of Schr\"{o}dinger's cat and squeezed states between the cavities modes is possible. Additionally, we show the effect of synchronization of cavity modes in a steady squeezed states at high fidelity realizable by the mechanical oscillator which intermediates the generation, transfer and stabilization of the squeezing. In this framework, we also have studied the generation and evolution of bipartite and tripartite entanglement and found its interconnection to the effects of transfer and synchronization. Particularly, when the transfer occurs at the maximal fidelity, at this instant any entanglement is almost zero, so the modes are disentangled. On the other hand, when the two bosonic modes are synchronized in a squeezed stationary state, then these modes are also entangled. The results found in this study may find their applicability in quantum information and computation technologies, as well in metrology setups, where the squeezed states are essential.

  Synchronization in quantum systems can be induced through applying dissipation on the central sites. Two types of synchronization, stemming from the topological edge states, are characterized by the off-diagonal or diagonal correlations between the boundary sites. Remarkably, the synchronous oscillations maintain steady amplitude and frequency in the thermodynamic limit.

  We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide.

We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

  We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
