Bitcoin faces a new quantum alert. Google Research now estimates that a future cryptographically relevant quantum computer could break ECDLP-256, the base of elliptical cryptography used in the ecosystem, with fewer than 500,000 physical qubits and in just a few minutes. The figure of "9 minutes" summarizes this acceleration, but Google's official formula remains more cautious: "a few minutes." The source text you provided goes in the same direction.
