dc.descriptionhe entropic uncertainty relation (EUR) [1], [2], [3] has various possible applications, including security [4], quantum memory [5], [6], quantum metrology [7], and quantum key distribution [8]. Quantum memory-assisted (QMA) entropic-uncertainty relation (QMA-EUR) is one of the major types of the EURs [9], [10]. QMA-EUR has been experimentally realized [11], [12]. Using the uncertainty Alice-Bob-game process based on two-qubit states, it is proven that the quantum states QMA-EUR and correlation are related [13], [14]. Bob prepares two entangled qubits, he sends one of them (measured system) to Alice and the other qubit (memory) is still with Bob. Alice carries on measurements and informs Bob of her outcomes.
dc.description.abstractThis study explores the dynamics of atomic entanglement of formation and entropic uncertainty relation (EUR) of two moving atoms interacting with an even coherent cavity during a two-photon interaction. We investigate the impact of the initial even coherent amplitude, the atom–photon coupling strengths, and the atomic motion coupling on the dynamics of quantum memory (QM) entropic uncertainty and entanglement. The dynamics of the entropic uncertainty and entanglement of formation are significantly altered by the atom-photon-atom interaction parameters. By increasing the initial mean photon number, the QM entropic uncertainty and the atomic entanglement can be improved. Bob's capacity to limit his uncertainty regarding Alice's measurement results depends on the initial even coherent state, the atom–photon couplings, and the atomic motion parameter. The atomic location couplings produce QM entropic uncertainty and entanglement with regular oscillatory behavior. The system parameters control the sudden death-birth entanglement phenomenon, which is improved by increasing the atomic location coupling. keywords: Atomic motion; Entanglement of formation; Entropic uncertainty; Quantum memory
