Nine minutes to a private key, read from a qubit lab
Google now estimates that a superconducting quantum computer with fewer than half a million qubits could recover a Bitcoin or Ethereum private key in about nine minutes, and it backed the claim with a zero-knowledge proof that Trail of Bits then forged. What the numbers assume, how close today's hardware is to them, and what it means for Solana, from someone who spends her days on superconducting qubits.
