Random entanglement percolation on realistic quantum networks
arXiv:2604.21967 · doi:10.1393/ncc/i2026-26176-2
The paper analyzes entanglement percolation in heterogeneous quantum networks by treating edge singlet‑conversion probabilities as random variables, and examines how polarization‑dependent loss in photonic links determines these probabilities.
Abstract
We study random entanglement percolation in heterogeneous quantum networks, where the singlet-conversion probabilities (SCPs) of the edges are drawn from a probability distribution rather than being fixed. After briefly recalling random classical and random quantum entanglement percolation, we focus on polarization-dependent loss (PDL) as a physical source of random edge entanglement in photonic networks. In this setting, polarization imbalance induces a simple map from the PDL magnitude to the edge SCP. We illustrate this map for representative PDL models and discuss the resulting implications for entanglement percolation.
