  The information scrambling in many-body systems is closely related to quantum
chaotic dynamics, complexity, and gravity. Here we propose a collision model to
simulate the information dynamics in an all-optical system. In our model the
information is initially localized in the memory and evolves under the combined
actions of many-body interactions and dissipation. We find that the information
is scrambled if the memory and environmental particles are alternatively
squeezed along two directions which are perpendicular to each other. Moreover,
the disorder and imperfection of the interaction strength tend to prevent the
information flow away to the environment and lead to the information scrambling
in the memory. We analyze the spatial distributions of the correlations in the
memory. Our proposal is possible to realize with current experimental
techniques.
