Quantum computing still seems to be at a pretty early stage. At the same time, it looks like it has the potential to do truly remarkable things. In at least one case, it did something a classical computer just can’t feasibly do: But that seriously understates what’s going on here. Every calculation that’s done on…… Continue reading A quantum computer did something a classical computer just can’t do
