Title: Simulation of Matrix Product States to Unveil the Initial State Dependency of non-Gaussian Dynamics of Kerr Nonlinearity
(Submitted on 19 Nov 2023 (v1), last revised 25 Apr 2024 (this version, v2))
Abstract: We simulate a free dissipative and coherent-driven Kerr nonlinear system using a time-evolving block decimation (TEBD) algorithm, to study the impact of the initial state on the exact quantum dynamics of the system. The superposition of two coherent branches results in non-classical time dynamics. The Wigner state representation confirms that the system ends up saturating to two different branches, through evolving different trajectories, resulting in de-Gaussification throughout evolution. Furthermore, we also see that the time evolution suffers a residual effect of the initial state.
