Summary

Story summary

Researchers developed a novel short time slot protocol that improves fidelity in quantum networks.
The approach maintains high fidelity over long distances by optimizing entanglement and swapping.
They formulated a new optimization problem, TETRIS, and created two algorithms, FNPR and FLTO.
Simulations show these algorithms outperform existing methods, delivering 60 to 78 percent gains overall and 20 to 75 percent in low entangling probability scenarios.
