Google quantum chip Willow cuts computation errors 40-fold, but bitcoin security threat still distant

Google succeeds in cutting errors in “magic state,” a key resource for quantum computing, to about one-fortieth of the previous level. Its Quantum AI team reports achieving 99.99% logical accuracy using its Willow processor, but the performance remains far from levels needed to crack bitcoin or RSA-2048 encryption. Researchers cite a wide gap in required accuracy and note that Willow has 105 physical qubits, far below estimates for such attacks.

Coinbase outlines quantum readiness roadmap for Bitcoin, discusses signature upgrade and inactive coins

Coinbase has released a draft discussion for Bitcoin’s transition to a post-quantum system, urging early preparation for signature upgrades and fund migration. It said ecosystem changes could take years and should begin before quantum computers can crack cryptography. Coinbase backed separating output types and signature methods, cited P2MR (BIP-360) and P2TRv2 as candidates, and urged caution on stateful signatures. It also called for separate approaches to inactive, lost and key-exposed coins.

Quantum computing threatens bitcoin, VanEck says solution exists even if slow

Bitcoin could be exposed to threats from quantum computing, but its community is already preparing responses, an assessment said. VanEck digital assets research head Matthew Sigel said bitcoin\'s decentralised structure could slow action, but technical solutions are being discussed. Industry concerns focus on whether future quantum computers could break bitcoin\'s cryptography, though none can do so now. Developers are testing quantum-resistant signatures, while Coinbase, Blockstream and a new security consortium are developing and backing proposals.
