According to 1M AI News monitoring, after Elon Musk on X reshared posts related to discussions about Google’s quantum-safe white paper, he joked: “Thinking on the bright side, if you forget your wallet password, maybe you’ll still be able to get it back in the future.”
This joke points to a white paper released today by Google’s Quantum AI team. Google says that in the future, breaking the 256-bit elliptic-curve encryption that protects systems like Bitcoin could require fewer than 500,000 physical qubits—about 20 times smaller than earlier estimates. Google also said the team has used zero-knowledge proofs to publish its findings without disclosing the attack roadmap, and it will continue with the post-quantum cryptography migration according to its 2029 timeline.
