Key Highlights: The Quantum Alliance estimates that between 6.04 million and 6.4 million Bitcoin—roughly 30% of the total supply, including Satoshi Nakamoto’s estimated 1.1 million BTC—are exposed to potential quantum vulnerabilities. Google Quantum AI announced a major breakthrough with its Willow processor, using “magic state cultivation” to cut quantum errors by a factor of 40 ...
Key Highlights: Google Quantum AI demonstrated “magic state cultivation,” reducing logical error rates from roughly 0.44% down to an upper bound of about 0.01% on its 105-qubit Willow chip. While an experimental milestone for fault-tolerant computing, the 40-fold error reduction does not accelerate timelines for cracking cryptographic schemes like Bitcoin and Ethereum’s secp256k1 curve. The ...
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 ...
