Where did they get from? Current estimates are tens of millions of qubits, and I don’t think that is likely to change. Also, a CRQC requires a low error rate as well. Just a lot of qubits does not make a quantum computer powerful. This is the “quality hype” that Google’s former head of quantum computing hardware said could be the death of quantum computer industry.

Cheers,
John

Subject: [Qirg] The Race to Save Our Secrets From the Computers of the Future
"China, Russia, and the U.S. are racing to find ways to prevent future quantum computers from cracking long-supported encryption protocols and endangering national security, the financial system, and critical infrastructure. Whereas the most powerful quantum device currently uses 433 quantum bits (qubits), tens of thousands or even millions of qubits would likely be necessary to break modern encryption systems. U.S. scientists are working to develop encryption systems that not even a powerful quantum computer can decipher, with the National Institute of Standards and Technology (NIST) expected to finalize its guidance for transitioning to the new systems next year. NIST said the federal government aims to migrate as much as possible to quantum-resistant algorithms developed through international academic collaboration by 2035. Many submitted algorithms—four of which NIST recommended for wider use—are lattice-based, which promise to complicate decryption exponentially as more dimensions are added."
