Motivation and main concerns go We investigate the dynamics of decorrelation under different choices of the pointer states of system reservoir couplings. In detail, we consider a two qubit system, initially prepared in certain states with non-zero quantum correlations, subjected to local dissipative channels responsible for various pointer states. Dynamical evolution of entanglement, quantum discord, and the mutual information sharing between the two qubits, is depicted. We elucidate various optimizations of the pointer states e.g., minimization and maximization of the conditional entropy, as well as the geometric optimization via minimizing discord, and analyze the properties of the corresponding behavior of decorrelation❖ We investigate the dynamics of decorrelation under different choices of the pointer states of system￾reservoir couplings.
