How to Avoid Exponentially Hard Problems in Digital Computing

The real question here is can quantum computers? run these exponentially large algorithms and once you hit 40 I Have as many possible paths as there are Adams in the universe, right? So one of the questions with quantum computers is that these quantum bits scale up exponentially. The idea is could a quantum computer Simulate the evolution through a search space Such that you can search an exponential number of options of paths in this world.
