Google says its Willow quantum chip reduced errors about 40 fold when preparing magic states, a critical resource for advanced quantum calculations. The development does not make a Bitcoin wallet attack imminent, but it highlights why older exposed public keys remain central to the quantum security debate.

Blockchains face a long-range security challenge as sophisticated actors collect encrypted data that could be decoded once quantum computing matures. Muriel Médard argues that post-quantum resilience can be built with classical coding techniques, including Random Linear Network Coding, rather than exotic hardware.
