QuEra + Harvard and MIT, has achieved 3,000-qubit array sustained for over two hours 96 logical qubits (executing algorithms) Basically we're close to 100 logical qubits sustained long enough to do real work. Also China is investing 5 times the US private sector, we have no idea the result, very secretive. They could be at 200, 300, no idea. The fact that you need ~2000 logical qubits and a few hours to crack a bitcoin key is well known, it's just math. Because shor's algo is being optimised it could go down th 1,800, 1,700, 1,600 logical qubits, we don't know. Also AI-assisted classic algos to shrink the quantum input. Basically it's happening. This is why Signal is *already* migrated, why government are saying 2030 no more non-quantum keys. Anyone calling quantum computing FUD has no idea what is going on. Odell up there is right to be talking about it.

“Big Jump” indeed. Like saying, now that a human has broke the 4minute mile, is just a matter of time before a human will break the 3 minute mile. Or 2 minute mile! A growing subset of theoretical (and Quantum) physicists pose doubt that such a “jump” is even possible. Should we be aware and paying attention? Yes. Running around like chickens with our heads cut off screaming “QC is weeks/months/a few years from breaking SHA256!!!”? No. Thats FUD.
