Google Issues New Warning About the Quantum Computing Security Apocalypse
Google has issued a new warning that the cybersecurity world should be prepared for “Q‑Day” - the moment when quantum computers can break today’s cryptographic systems - as early as 2029. The shift follows research suggesting that a 2048‑bit RSA key could be cracked in under a week using a quantum machine with one million noisy qubits, a far more achievable threshold than previously assumed. While current quantum computers remain too error‑prone to pose an immediate threat, Google urges the security community to accelerate the transition to post‑quantum cryptography. The update signals that quantum capabilities once thought decades away may arrive sooner than expected.
