I'm not sure the halved doubling time for quantum computers is right.

Maybe I'm not getting into the spirit of accepting the proposed counterfactuals - but is quantum computer performance doubling regularly at all? It seems more as though it is jammed up against decoherence problems already.

It's a purely theoretical counterfactual about the combination of Moore's law and Grover's algorithm.

Moore's law says that the computer becomes twice as efficient in 18 months. Grover's algorithm says that the time taken by a quantum computer to solve SAT is the square root of the time required by a classical computer. Thus in 18 months, Moore's law of hardware should make the quantum computer 4 times as fast.

I guess that quantum computers halve the doubling time, as compared to a classical computer, because every extra qubit squares the available state space. This could give the factor two in the exponential of Moore's law. Quantum computing performance currently isn't doubling but it isn't jammed either. Decoherence is no longer considered to be a fundamental limit, it's more a practical inconvenience. The change that brought this about was the invention of quantum error correcting codes. However experimental physicists are still searching for the ideal practical implementation. You might compare the situation to that of the pre-silicon days of classical computing. Until this gets sorted I doubt there will be any Moore's law type growth.
