Google Willow Chip Breakthrough Raises Quantum Threat to Satoshi-Era Bitcoin

Key Highlights: Early Bitcoin addresses, especially those mined during the network’s earliest days, carry exposed public keys directly on-chain, rendering physical recovery phrase security ineffective against theoretical quantum attacks. While newer Bitcoin transaction formats keep public keys obscured behind address hashes until funds are spent, upgrading unspent legacy coins requires existing private keys that lost-coin ...

Google Achieves ‘Magic State’ Quantum Breakthrough as Top 5 Quantum-Proof Blockchains Emerge

Key Highlights: Google Quantum AI has achieved “magic state cultivation” on physical hardware, cutting error rates 40-fold on its Willow processor while using only about half of its 105 physical qubits. Despite the leap forward, existing cryptocurrencies like Bitcoin remain secure for now, as breaking Elliptic Curve Cryptography (ECC) requires a 100,000x scaling of current ...

The Quantum Issue: Quantum Computing Isn’t Coming for Your Bitcoin

Key Highlights: Recent quantum-computing advances do not yet demonstrate a clear, linear path to a cryptographically relevant quantum computer (CRQC). Neutral-atom devices are among the more promising developments, but it remains too early to know whether any current technology can reach the required scale and stability. Bitcoin developers should continue pursuing post-quantum cryptographic upgrades despite ...
