That's what I'm saying. I don't really mean never, but I don't see why we have good reason to believe we'll reach that threshold this millenium.
Until then, the best we can do is if you half the noise floor (or double the fidelity) you can add roughly one ideal qubit.
- jessriedel 3y agoYou can't double the fidelity because it's already much larger than 1/2, and if you mean halving the infidelity then this doubles the depth of the deepest circuit you can perform (not just increasing it by one layer). And none of that leads to an ideal qubit. The most obvious reason to suppose the fault tolerance threshold will be crossed is that simple extrapolation of progress predicts it will.
