| contents | Entanglement swapping is a fundamental protocol in quantum information processing that enables the distribution of entanglement between distant quantum systems. In this work, we first extend the concept of entanglement swapping to higher-dimensional quantum systems, specifically qudits. We then analyze the dynamics of entanglement swapping and quantify the average swapped entanglement in terms of concurrence and negativity. Our results demonstrate that higher-dimensional systems offer enhanced entanglement distribution capabilities compared to qubit-based protocols. We also discuss the application of entangled qudits in terms of long-distance teleportation that provides the base for quantum repeaters. Furthermore, we discuss the entanglement swapping for a real and noisy system. The behaviors of entanglement against fidelity with different dimensions are also discussed. |
