Abstract
Entanglement swapping is the cornerstone of quantum networks,while quantum information masking is a method to ensure data privacy. The combination of the two can open new perspectives for ensuring information security in quantum network environments. In this paper, we study entanglement swapping with information masking. We consider the entanglement swapping that combines several quantum information masking methods, including the entanglement swapping of two-particle entangled states and multi-particle ones. Based on our previous work [2025, arXiv, 2009.02555v11], we derive the entanglement swapping formulas. Besides, we put forward some hypotheses about observers, which, although not the main focus of this paper, can inspire people to rethink quantum mechanics phenomena and the relationship between humans and nature.
