Summary

Story summary

Cloudflare and other cybersecurity firms are reevaluating defenses after two preprint studies suggested quantum computers capable of breaking encryption could emerge sooner.
Researchers, including those from Oratomic, say cracking common security technologies may require as few as 10,000 qubits, far lower than earlier estimates.
The findings have sparked urgent discussions among academics and industry professionals about timing, risks, and mitigation strategies, with broader implications for science and industry.
