>>17Quantum computers can feasibly simulate quantum simulations interactively; digital computers won't be able to simulate quantum simulations interactively. A 3D simulation where individual particles (or voxels or atoms) interact with one another is not something that digital computers will do so efficiently as compared to quantum computer. This is the reason why destructible 3D environments are so limited in contemporary gaming - there's just too much information to simultaneously process using digital systems. Contemporary 3D games with destructible environments are quite limited in the sort of things that can be interacted with or destroyed.
