- Abstract: Quantum network applications like distributed quantum computing and quantum
secret sharing present a promising future network equipped with quantum
resources. Entanglement generation and distribution over long distances is
critical and unavoidable to utilize quantum technology in a fully-connected
network. The distribution of bipartite entanglement over long distances has
seen some progresses, while the distribution of multipartite entanglement over
long distances remains unsolved. Here we report a two-dimensional quantum
repeater protocol for the generation of multipartite entanglement over long
distances with all-photonic framework to fill this gap. The yield of the
proposed protocol shows long transmission distance under various numbers of
network users. With the improved efficiency and flexibility of extending the
number of users, we anticipate that our protocol can work as a significant
building block for quantum networks in the future.
