Summary

Story summary

Researchers from the University of Massachusetts Amherst and Inria, Paris, find that randomness in Gaussian Boson Sampling obscures signals from hidden structures, hindering planted biclique detection.
They analyze node weights derived from Gaussian Boson Sampling outputs.
Natural fluctuations in these weights overwhelm signals of a planted biclique.
The study suggests detection may remain difficult even with quantum computing.
Future work may explore alternative GBS statistics or other quantum paradigms.
