Entangling power is crucial for quantum information processing. This study examines the anti-Jaynes–Cummings model (AJCM) in generating quantum correlations between two atoms interacting via the Ising model and its effect on the entangled system. The AJCM is shown to create entanglement suitable as a quantum channel for information encoding. Interaction parameters act as controls to enhance quantum correlations, increase the capacity of the final atomic state, and improve system efficiency. When the atomic system starts in a maximally entangled state, increasing interaction strength and mean photon number further boosts concurrence and channel capacity.
