  In this paper, we present a collision model to stroboscopically simulate the
dynamics of information in dissipative systems. In particular, an all-optical
scheme is proposed to investigate the information scrambling of bosonic systems
with Gaussian environmental states. By varying the states of environments, we
find that in the presence of dissipation the transient tripartite mutual
information of system modes may show negative value signaling the appearance of
information scrambling. We also find that dynamical indivisibility based
non-Markovianity play dual roles in affecting the dynamics of information.
