Re: Conventional supercomputer?
"Regardless of what IBM says, I think Google's claim still stands - you can hardly call a supercomputer as being "conventional"
You need to include price as well for both sides - QC's aren't cheap or readily available at the moment and doing "just enough" to demonstrate they are faster than conventional, general purpose systems maybe setting the bar too low.
Given that Google will likely exceed their current QC compute levels, pointing at the exact system that will be considered equivalence is likely to change when we look back - I think it will be higher than the current estimates until QC can handle a wide range of problems and become practical replacements for large, conventional, facilities like the one IBM has highlighted. However, this is likely a matter of time and those with functioning, high qubit equipment are the groups likely to succeed at this task.
The problem for IBM is that history will forget the doubters and the losers...
