| Abstract: | This study investigates the dynamics of the quantum memory-assisted entropic uncertainty relation (QMA-EUR) and the atomic entanglement of formation, both induced by the interaction of maximally entangled two-qubit systems with spatially separated coherent cavities, under two types of decoherence: intrinsic decoherence and Ohmic environmental decoherence. The controllable dynamics of the entropic uncertainty and the lower bound (Berta's bound) and atomic entanglement between are investigated under the physical coupling effects of the cavities' initial coherent field amplitudes, the nonclassicality associated with coherent and even coherent states, detuning between the qubits and cavities, and intrinsic decoherence rate. The interactions between the pair of atomic qubits and spatially separated coherent cavities induce regular anti-correlated oscillatory dynamics of the entanglement of formation and the QMA-EUR quantifiers, which depend on the underlying physical couplings. It is resulted that the decoherence-induced effects—including the extension of disappearance intervals of quantum memory resource, the disappearance of recurrent maximally entangled states, the upward shift of entropic uncertainty minima—are influenced by both the nonclassicality of the initial coherent cavity states and the qubit-cavity detuning parameters. Increasing the detuning couplings further amplifies these decoherence effects. It is found that the dephasing dynamics of QMA-EUR and atomic entanglement of formation, associated with the generated maximally entangled state (due to the intrinsic decoherence model) and influenced by externally applied Ohmic noise, are strongly dependent on the initial cavity-coherent-field amplitudes of the cavities, the degree of nonclassicality inherent in both coherent and even coherent states, the detuning between the qubits and the cavities as well as on the decoherence.
