Abstract: In 2015 we suggested an experimental nonlinear optical system to simulate the Newton-Schrodinger equations [1]. A model that unifies quantum mechanics with Newtonian gravity, describing the gravitational self-interaction of a quantum wavepackets. Recently, we broke the Newtonian limit suggesting the Post-Newtonian Schrodinger equations and a system to experimentally simulate its dynamics. In this talk I will present new solitonic solutions of the Post-Newtonian system and experimental simulations done with optical beams propagating in a nonlocal nonlinear medium. In the second part of the talk I will present our efforts toward solid-state based quantum metasurfaces [2] with subwavelength atomic-like arrays. Specifically with arrays of Silicon-Vacancy centers in diamond that have proved as promising emitters for quantum information [3,4]. Analysis of new entanglement generation protocols will be presented along with an overview of our experimental setup in my recently established lab.
