“…The modifications of the light beam propagating through media give rise to identical effects, such as shift peak and shape distortions of the transmitted pulse [25][26][27], in both the classical and quantum domains. However, incident light with a nonclassical nature may exhibit some alterations in the squeezing and quantum coherence that can only be described in the framework of full quantum theory [25][26][27][28][29][30][31][32][33][34][35]. Despite the successful implementation of PT -symmetry in the classical systems, some controversial results are proposed in the full quantum regime, such as ultrafast states transformation and the violation of the no-signaling principle [36,37].…”

We investigate the propagation of a normally incident squeezed coherent state of light through dispersive non-Hermitian optical bilayers, particularly at a frequency that the bilayers hold parity-time (PT) symmetry. To check the realization of PT-symmetry in quantum optics, we reveal how dispersion and loss/gain-induced noises and thermal effects in such bilayers can affect quantum features of the incident light, such as squeezing and sub-Poissonian statistics. The numerical results show thermally-induced noise at room temperature has an insignificant effect on the propagation properties in these non-Hermitian bilayers. Moreover, tuning the bilayers’ loss/gain strength, we show that the transmitted squeezed coherent states through the structure can retain to some extent their nonclassical characteristics, specifically for the frequencies far from the emission frequency of the gain layer. Furthermore, we demonstrate, only below a critical value of gain, quantum optical effective medium theory can correctly predict the propagation of quantized waves in non-Hermitian and PT-symmetric bilayers.

“…The scattering of quantized waves from a dispersive and absorptive medium at rest has been discussed in Refs. [38][39][40][41][42][43][44][45][46][47], but to the best of our knowledge, this problem has not been studied before for the case of a moving medium whose velocity may have any value up to the speed of light in free space. In this contribution, we intend to discuss such scattering behavior in detail.…”

Within the framework of a phenomenological quantization scheme, we present the quantization of the electromagnetic field in the presence of a moving absorptive and dispersive magneto-dielectric slab (MDS) with uniform velocity in the direction parallel to its interface. We derive the quantum input-output relations for the case that quantum states propagate perpendicularly to the moving MDS. We thoroughly investigate the impact of the motion of the moving MDS on quantum properties of the incident states. To illustrate this, by modeling the dispersive and dissipative effects of the slab by the Lorentz model in its rest frame, we compute the quadrature squeezing and the Mandel parameter for the transmitted state when the incident states from left and right sides are, respectively, the coherent and the quantum vacuum states. It is shown that how quantum features of the incident state are degraded when it is transmitted through the moving MDS.

In this paper, we construct the m-photon-added and m-photon-subtracted coherent states on a sphere. These states are shown to satisfy the usual conditions of continuity in the label, normalizability and the resolution of identity. The preparation of the constructed states, as the states of radiation field is considered. We examine and analyze the nonclassical properties of these states, including the photon mean number, Mandel parameter and quadrature squeezing. We find that these states are sub-Poissonian in nature, whereas the degree of squeezing is reduced (enhanced) by increasing m for the photon-added (photon-subtracted) coherent states on a sphere.
