Why Google’s new breakthrough quantum research focuses on Bitcoin rather than banking or nuclear codes

On Mar. 30, Google Quantum AI published a 57-page whitepaper coauthored with Justin Drake of the Ethereum Foundation and Dan Boneh of Stanford. The paper demonstrates that breaking the 256-bit elliptic-curve discrete logarithm problem, the cryptographic foundation underlying most blockchain transactions, requires roughly 500,000 physical qubits, a 20-fold reduction from prior estimates. That compression means [ ]
