They are fundamentally analog machines. Digital computers have huge error bars, its basically impossible for a transistor to bit flip naturally. A small change in voltage does not change the represented value. This is untrue of quantum machines, where a small fluctuation in the qubit’s underlying state actually causes a change to the represented value.
We have already done tons of research into what we can do with quantum computers. Theoretical quantum computer science is a well researched field. Basically the only thing we’ve gotten out of it is Shor’s algorithm. Its honestly just not that useful even if we had high breakthroughs in the engineering.
