We propose a scheme to implement a fast modulation of the boundary conditions by tuning the applied magnetic flux through superconducting quantum interference devices (SQUIDs) localized in the middle of the transmission line resonator (TLR). In the ultra-strong coupling regime of light-matter, we show that this model allows the observation of vacuum fluctuations by turning the virtual photons into a real ones. Furthermore, we analyze the phase space properties of our scheme by using the Wigner distribution function. Finally, we map our system to the ground state in order to show the creation of a genuine quantum entanglement and compare it to the strong coupling regime.
