Influence of Local Entanglement Swapping to Quantum Random Networks Robustness

Abstract

Abstract:

Entanglement percolation was used to establish long-distance entanglement between arbitrary nodes of quantum random networks. There is a local entanglement swapping operation for the network. This operation changes the local connection of the network, which also lead to the entire network topology structure is changed. It mainly discusses the influence of local operation to quantum networks robustness. When there are operation, we through theoretical analysis and numerical simulation find that the number of the larger degree nodes increase significantly and the threshold value changes less. This suggests that local entanglement swapping can greatly improve the quantum random networks robustness.

Key words: Quantum Random Networks, Entanglement Percolation, Entanglement Swapping, Robustness
