This paper investigates the entanglement dynamics of a two‐qubit system in the presence of n‐sequential sin 2‐pulse shape. The study explores entanglement under two scenarios: when the system is completely isolated from the environment and when it interacts with one of the surrounding environments, namely the thermal environment and the common dephasing environment. The authors quantify entanglement through concurrence while systematically examining the effects of initial state preparation, qubit coupling strength, laser‐qubit interaction intensity, pulse sequences, and decohering environments. The results highlight that the entanglement of the two‐qubit system strongly depends on the initial state. Increasing the coupling strength between the qubits and the n‐sequential pulse enhances the maximum values of entanglement. Conversely, augmenting the laser‐qubits coupling or introducing the influence of the environment diminishes the entanglement.
