  We estimate the net information exchange between adjacent quantum subsystems
holographically living on the boundary of $AdS$ spacetime. The information
exchange is a real time phenomenon and only after long time interval it may get
saturated. Normally we prepare systems for small time intervals and measure the
information exchange over finite interval only. We find that the information
flow between entangled subsystems gets reduced if systems are in excited state
whereas the ground state allows maximum information flow at any given time.
Especially for $CFT_2$ we exactly show that a rise in the entropy is
detrimental to the information exchange by a quantum dot and vice-versa. We
next observe that there is a reduction in circuit (CV) complexity too in the
presence of excitations for small times.
