On the Analysis of a Multipartite Entanglement Distribution Switch

2020 · Proceedings of the ACM on Measurement and Analysis of Computing Systems

We study a quantum switch that distributes maximally entangled multipartite states to sets of users. The entanglement switching process requires two steps: first, each user attempts to generate bipartite entanglement between itself and the switch; …

On the Stochastic Analysis of a Quantum Entanglement Distribution Switch

2021 · IEEE Transactions on Quantum Engineering

In this article, we study a quantum entanglement distribution switch that serves$k$users in a star topology. We model variants of the system as continuous-time Markov chains and obtain expressions for switch capacity, expected number of …

Optimal entanglement distribution policies in homogeneous repeater chains with cutoffs

2023 · npj Quantum Information

We study the limits of bipartite entanglement distribution using a chain of quantum repeaters that have quantum memories. To generate end-to-end entanglement, each node can attempt the generation of an entangled link with a neighbor, …
