We investigate the medium effect of the two-layer parity time (PT) symmetric on the quantum optical properties of an incident squeezed light at zero temperature. For this purpose, we calculate the quadrature squeezing of the output states of a two-layer PT, using the canonical approach in quantization of the electromagnetic field and modeling the electric permittivity functions of the constituent layers by the Lorentz model, for a situation in which the incident states on the right and left side of the two-layer PT are the quantum vacuum and squeezed states, respectively. It will be shown that although the PT loss effect is compensated in the phase symmetry regime, the output light is no longer squeezed.
