Entanglement swapping is a key technology to realize long-distance quantum communication and build quantum networks, and has extensive and important applications in quantum information processing. In this paper, we propose a new algorithm to obtain entanglement swapping results, which is based on the idea of constructing new entangled states after entanglement swapping from all possible observation outcomes. We demonstrate the algorithm by the entanglement swapping between two bipartite entangled states, and derive the results of entanglement swapping between two 2-level Bell states, which are consistent with those obtained through algebraic calculations. Our work can provide new perspectives for thinking about the principles of quantum mechanics and trigger in-depth exploration of quantum mechanics principles and natural mysteries.

Entanglement swapping is one of the most peculiar quantum mechanical phenomena, which is a key technology to realize long-distance quantum communication and build quantum networks, and has extensive and important applications in quantum information processing. In this paper, we combine some principles of classical physics with those of quantum mechanics to propose a new theoretical framework and design a new algorithm for entanglement swapping based on it, the basic idea of which is to construct two entangled states after entanglement swapping from all possible observations. We demonstrate the algorithm by the entanglement swapping between two bipartite entangled states, and derive the results of entanglement swapping between two Bell states, which are consistent with those obtained through algebraic calculations. Our work not only provide new perspectives for exploring quantum mechanical phenomena and the principles behind them, but also can trigger in-depth exploration of the mysteries of nature.
Entanglement swapping has important applications in various fields such as quantum information processingand the preparation of entangled states. In this paper, we propose a new algorithm for deriving entanglement swapping results. The basic idea of our algorithm is to deduce the entanglement swapping results from all possible observation results, which is simpler than existing algorithms. We demonstrate the algorithm by the entanglement swapping between two bipartite entangled states, and derive the results of entanglement swapping between two 2-level Bell states, which are consistent with those obtained through algebraic calculations.
Since its establishment, quantum mechanics has developed for a century and has a very large theoretical system,but the phenomenon of quantum mechanics still lacks a generally accepted explanation,which undoubtedly shows that the existing theoretical system is incomplete.Inspired by ancient Chinese philosophy, we propose a new theoretical framework based onsome existing principles of classical physics and quantum mechanics,which opens a new perspective for the interpretation of quantum mechanics.Furthermore, based on this framework, we design a new algorithm for entanglement swapping,the basic idea of which is to derive two entangled states created by entanglement swapping from all possible observations.We demonstrate the basic idea of the algorithm through the entanglement swapping between two bipartite entangled states,and derive the results of the entanglement swapping between two Bell states,which is surprisingly consistent with those obtained through algebraic calculations.Of course, through the proposed algorithm, the correctness of the proposed theoretical framework can be verified.Our work will contribute to a deeper exploration of the mysteries of nature, including quantum mechanical phenomena.
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.
The quantum information network is important in establishing next-generation technology. In particular, maximal and long-distance entangled states are important in realizing a number of quantum information technologies, such as teleportation, key distribution and so forth. Entanglement swapping is a scheme that creates a long-distance network by using multiple short ones. Entanglement swapping protocols applied to non-maximal correlations have been thoroughly investigated by various people. Rather than providing any new analytic results, some examples of a numerical approach will be provided in this paper. In particular, the paper reveals the existence of different classes of coefficients that approximate the optimal outcome ( i.e. , the weaker average maximal entanglement between the two initial states). The new class of states is non-trivial in the sense that their coefficients are just as widely distributed as the coefficients of states satisfying optimality conditions are. Moreover, we will numerically examine entanglement swapping methods and show the distribution of optimal and general coefficients for three and four 2-level correlations.
Entanglement swapping is not only one of the core resources of quantum information processing, but also the backbone of long-distance quantum communication and quantum networks. Naturally, quantum information processing schemes based on entanglement swapping, such as quantum cryptography protocols and quantum algorithms, are more adaptable to quantum network environments. In this paper, we achieve quantum anonymous computation through entanglement swapping, the basic idea of which comes from our previous work [2019, Quantum Information Processing, 18(6), 168]. We propose two quantum anonymous computation protocols, in which entanglement swapping plays a crucial role in transmitting information and enhancing information security.
