- Abstract
Anonymous entanglement refers to the construction of entangled channel between two parties among the quantum network, while keeping the identities of these two parties unknown to other parties. A recent work of [A. Unnikrishnan et al., Phys. Rev. Lett. 122, 240501 (2019)] proposed the first anonymous entanglement protocol in the presence of malicious parties and untrusted source. However, the correctness of the original protocol will be threatened, considering that the generated entangled channel can be destroyed by malicious parties without being detected. In this paper, we propose an improved protocol, which ensures the anonymity of the parties and the correctness of shared entanglement channel simultaneously. Furthermore, we consider the noisy measurement in the security analysis, which makes our protocol practical and rigorous. Based on the security analysis, genuine multipartite entanglement could be certified in the untrusted quantum network with our protocol.
