Google Says End For Bitcoin Is Near? Quantum Computers Could Attack Crypto This Soon

It sounds out of a sci-fi video game, but new research suggest quantum attackers could break Bitcoin’s blockchain and steal coins mid-transaction sooner than it was originally expected. Is Doomsday Near For Bitcoin? A new whitepaper and blogpost published on Tuesday by Google’s Quantum AI team claims that Bitcoin and Ethereum’s cryptography can be broken with fewer than 500,000 physical qubits and roughly 1,200 “logical” qubits, far below the “millions” that used to be cited.

The research points at a significant decreased in the resources needed to break the ECDLP-256. The blog post says: We estimate that these circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical q
