Seems corroborated in this article? Quantum computing breakthrough could happen with just hundreds, not millions, of qubits using new error-correction system (msn.com) Denis Mandich, is the chief technology officer for the quantum computer company "Qrypt" and is quoted as saying: “With just 300 logical qubits, you have more compute power than has ever existed and could ever exist if you turned every atom---every atom in the universe---into a supercomputer,” We don't know how good quantum error correcting algorithms can get but estimates are that it will take between 10,000 and 100,000 of today's best physical Qubits to make one logical Qubit that has an error rate of 10^-15, which is what you need for a quantum computer to become practical. And as of today, the lowest physical Qubit error rate so far was 10^-6, one error per million operations, achieved by researchers in Sydney Australia. The better the physical Qubit is, the fewer of them you need to make a near perfect logical Qubit, and I have no doubt that over time both physical Qubits and quantum error correcting algorithms will get better, but I don't know how much time or how much better. John K Clark See what's on my new list at Extropoliseqq While adopting new algorithms will secure future communications, anyone with the capacity to intercept and record messages now can hold on to them until the time large scale quantum computers can be developed to break the old encryption. There will be some advantage to the first one to get such a computer (assuming that one also has the recorded communications protected with current algorithms).

But us getting big QC first doesn't affect that. What we need to do is change to encryption not susceptible to QCs, something we are already doing. I has nothing to do with how fast be make big QCs.
