[Nobel Physics Prize Winner Warns: Bitcoin Faces Quantum Computing Threat, Window Period Approaching] Odaily Planet Daily reports that former Google quantum hardware lead and 2025 Nobel Physics Prize winner John Martinis has warned that Bitcoin could become one of the first real-world targets of quantum computing attacks. He stated that recent research by Google indicates that advanced quantum computers might be able to derive Bitcoin private keys within minutes, significantly reducing the computational security barriers currently relied upon by the network. Since Bitcoin relies on elliptic curve cryptography and its network upgrades are slow and decentralized, this makes quantum threats harder to address compared to traditional financial systems. The exposure window of public keys during Bitcoin transaction broadcasts could be exploited by quantum computers to intercept funds before the transaction is fully confirmed. John Martinis emphasized that while building such quantum computers remains a highly challenging engineering task, the community must not take this threat lightly. He recommends planning quantum-resistant upgrades as early as possible, with related threats expected to gradually emerge within the next 5 to 10 years. (CoinDesk)
