Well if we're counting every quantum interaction that would take a long time to solve on a classical computer as 'computational advantage' then arguably any nontrivial quantum interaction would do the trick. And as far as I can tell it's not calculating something that anyone would consider useful, so it's a bit debatable in what respect this result is any different.
So well, it depends on your perspective I guess.
- clavigne 5y agoThat's been the problem with the Google result too, even though they did have "controlled" operations. They basically showed that a quantum computer doing random operations has an output that is difficult to predict with classical simulation. It also solves no problem at all. They tried to shoehorn into the paper a "CSRNG" application but it's dubious at best if you have any kind of cost constraint.
