I'm curious if they would manage even a single bit ECDLP with Shor's algorithm. As mentioned on the website 3-bit would be a breakthrough.
Error-prone qubits - Today's qubits have 99% - 99.9% fidelity - is that good enough?
99.9% fidelity might be enough for lg2(1000)=10 bit RSA via Shor's, maybe, sometimes.
For a 25 bit one would need 99.999997% fidelity, not only in qubits, but Toffoli (or whatever) gates as well.
I'm not sure what these 99.9% mean though. In what time frame is the error so low? After all, more time equals more noise. If I got it correctly, let it be 99.9% for 1 nanosecond, it would get down to 99% in just 10 nanoseconds, then 90% in 100 ns, and then is kinda gone with 1% in 1 microsecond.
