Google warned that quantum advances could break crypto security sooner than expected, with analysts recommending ‘appropriate urgency.’

A team of Google researchers just set a new date for post-quantum cryptography migration: 2029. Among other things, this means that Bitcoin, as well as many other cryptocurrencies, needs to adopt new cryptographic techniques that are resilient to quantum attacks within three years.

Google's new whitepaper says it could take only minutes for a quantum system to crack Bitcoin.

CZ took to X saying there’s “no need to panic” as it’s only about crypto needing to upgrade to quantum-resistant (post-quantum) algorithms. Google: Quantum computers may break Bitcoin, Ethereum security Fewer than 500,

Google Quantum just cut the qubit requirement to break Bitcoin encryption by 20x, and 6.7 million crypto addresses are in risk.

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100,000 qubits and 10 days to break, according to the researchers, from Caltech and quantum computing company Oratomic in Pasadena, Calif.
