摘要：

We present an approach to entanglement purification on complex quantum network architectures, that is, how a quantum network built from repeaters with limited processing fidelity can purify and distribute entanglement between users. In particular, we explore how noisy gates, depolarizing channels, and finite memory storage time influence the performance of entanglement purification in a quantum network. Finally, we apply the purification techniques we developed in the context of entanglement routing for different quantum network topologies in an effort to inform future design choices for quantum network configurations.
