Abstract: In this paper, we estimate the net information exchange between adjacent quantum subsystems holographically living on the boundary of [Formula: see text] space–time. 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 [Formula: see text] 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.
