Q-Day Just Got Closer: Three Papers in Three Months Are Rewriting the Quantum Threat Timeline

AI-summarised brief · reviewed before publication

Quantum threat assessments have been significantly revised in recent months, with three research papers reducing the estimated resources needed to break modern encryption. The estimated qubits required to factor RSA-2048 have dropped from 20 million to fewer than one million, and potentially fewer than 100,000 under newer architectures. This shift represents the most significant update since 1994, prompting concerns among CISOs, CTOs, and policymakers to reassess quantum risk as a pressing issue.
