- Abstract: Inspired by the discrete-variable pairwise entanglement, in this work, we in
theory analyze the continuous-variable pairwise entanglement between microwave
modes based on a hybrid optoelectromechanical system, where the multi-pair
microwave superconducting circuits simutaneously interact with each other via a
mechanical resonator, which forms a Fabry-P\'erot cavity along with a standing
mirror. With experimentally reachable parameter settings, wanted entanglement
can be acheived when the pair number up to 10, and more is also available,
which has the potential to be useful in quantum technologies where the demand
for scalability and intergration is continuously increasing.

We compare four criteria for continuous-variable entanglement, which serve as sufficient conditions for determining the separability of Gaussian two-mode states.
Our findings indicate that while the applied inseparability criteria show similar entanglement patterns within specific parameter ranges, the degree of entanglement varies depending on the chosen criteria.

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

We study the dynamics of a pair of optomechanical systems interacting dissipatively with a wave guide in a unidirectional way.
We explore both classical and quantum correlations established between the modes in both the transient and in the stationary regime.
We show that this unidirectional coupling establishes a temperature gradient between the mirrors, depending on the frequencies' detuning.

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.
