We have studied quantum effects in a system governed by the spatial nonlinear Schrodinger equation derived for a two beams interaction in a quadratic nonlinear material. For a quadratic nonlinear material it has recently been demonstrated [2, 3] that, under suitable conditions, in the interaction between the fundamental and the second harmonic field, the fundamental field propagation can be described as a solution of a nonlinear Schroedinger equation, given in terms of spatial solitons [4,5]. In this work we are interested at the quantum properties of the fundamental beam in this kind of interaction. We use a quantum field description [1] where the spatial variable of propagation z plays the role of time in the standard quantum theory, and we apply it to the case of a strong plane wave that can be described as a classical field propagating through the nonlinear medium in the z-direction. We assume TE polarizations for all the monochromatics fields involved into the interaction in a type I material.

Quantum material design presents a significant challenge due to the complexity of exploring the vast space of possible material structures. This paper introduces a novel approach – Adaptive Lattice Mapping – that leverages quantum algorithms to dynamically adjust the structure of quantum materials, enabling the efficient discovery of materials with tailored properties. The core mechanism involves a quantum optimization process that iteratively refines lattice configurations to achieve desired performance characteristics. This method offers a fundamentally new pathway for materials discovery, potentially accelerating the identification of materials with enhanced functionalities.
