Elon Musk sharply criticizes Google's quantum paper: Maybe you'll be able to recover after forgetting your wallet password

Elon Musk jokes about Google's quantum security white paper, suggesting that in the future, forgotten wallet passwords might be recovered. Google states that the number of qubits needed to crack 256-bit encryption will be reduced to 500,000 and commits to continuing research on post-quantum cryptography.

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.
