Not solved, no. Definitely much much better than before. The difference AlphaFold made is significant: we’re talking about getting a decent model in a couple minutes using a PC compared to several months of calculations before.

However we still need experimental data: in many occasions AlphaFold gives an incorrect model. With some experimental data that model can be improved, but we still have no reliable way to know what the structure of a protein is starting from the amino acidic sequence without extensive experimentation.

That’s the big promise of quantum computers, there are however two major problems in my opinion:

1. There’s still no theoretical framework which explains how once we have a quantum computer we may tackle protein folding
2. Plenty quantum computing companies closed shortly after AlphaFold was published since they lost all funding because protein folding was “solved”

Maybe samurai just needed bigger pockets
