A chip-scale source of topologically protected entangled photonic states could be tested in existing quantum networking testbeds within two years.
Topological photonic modes can be less sensitive to fabrication disorder, and programmable preparation could be implemented on silicon photonic foundry processes already used for entangled photon pair generation. If the protocol in the preprint works with standard fabrication tolerances, integrating it into testbeds is an incremental engineering step rather than a new physics requirement.
