Statistical limits for entanglement swapping with semiconductor entangled photon sources

Semiconductor quantum dots are promising building blocks for communication applications. Although deterministic, efficient, and coherent emission of entangled photons has been realized, implementing a practical repeater remains outstanding. Here we explore the statistical limits entanglement swapping with sources polarization-entangled from commonly used biexciton-exciton cascade. We stress necessity tuning exciton fine structure, explain why often observed time evolution photonic in is not applicable large networks. identify critical, statistically distributed device parameters based on two sources. A numerical model benchmarking consequences fabrication, dynamic techniques, effects developed, order to bring realization semiconductor-based networks one step closer reality.
