Summary

Story summary

A team from the University of the Witwatersrand (South Africa) and Huzhou University discovered a hidden topological structure in quantum entanglement of photons generated by spontaneous parametric downconversion.
The structure spans 48 dimensions and more than 17,000 signatures, revealing a potential new method to encode quantum information.
Published in Nature Communications, the work suggests increased resilience to noise and notes that existing lab resources can explore these topological effects.
