On the Capacity Region of Bipartite and Tripartite Entanglement Switching

We study a quantum switch serving set of users in star topology. The function the is to create bipartite or tripartite entangled state among at highest possible rates fixed ratio. model randomized switching policies. Discovering that some are better than others, we present analytical results for case where stores one qubit per user, and find best policies outperform time division multiplexing (TDM) policy sharing between generation. This performance improvement decreases as number grows. easily augmented capacity region presence decoherence, obtaining similar results. Moreover, decoherence appears have little effect on capacity. also smaller class when two qubits user.
