Quantum Threat: Google Moves Up Cryptography Deadline
26 Mar
Summary
- Google now expects quantum computers to break security by 2029.
- One million noisy qubits could factor RSA keys in under a week.
- This shifts preparation for post-quantum cryptography forward.
The timeline for 'Q-Day,' the theoretical moment quantum computers can break all cryptographic security, has been drastically shortened by Google. The company now anticipates this eventuality by 2029, a significant acceleration from previous estimates. This adjustment requires the security community to expedite its transition to post-quantum cryptography (PQC).
This revised deadline is reportedly influenced by research indicating a quantum computer with one million noisy qubits could factor a 2048-bit RSA integer in less than a week. Previously, such a feat was thought to require a billion precise qubits. This development signals a remarkable and potentially concerning leap in quantum computing capabilities.
