If quantum supremacy was not possible, wouldn't that mean that something is wrong with our physics understanding?
So when people say quantum supremacy is impossible, do they say that the device itself is extremely complicated to build (like an earth to moon elevator for example), or that quantum supremacy isn't allowed not even in principle?
