Recent research indicates that building a quantum computer capable of breaking elliptic-curve cryptography (ECC) is becoming easier and faster than previously thought. One study shows it could crack ECC in just 10 days, while another demonstrates breaking ECC-secured blockchains in under nine minutes. Both papers highlight significant progress in quantum computing capabilities, though neither has been peer-reviewed.

• A neutral-atom qubit approach could crack 256-bit ECC in 10 days using 100x less overhead than prior estimates.
• A Google team claims to break ECC securing Bitcoin-like cryptocurrencies in under nine minutes, a 20-fold resource reduction.
• Neither whitepaper has been peer-reviewed, so the claims remain unverified.
• Experts say the results don't pin down a timeline for practical quantum decryption, but confirm steady, unslowing progress toward it.
