CUDA is not magic. With enough work, you can get about 10x speedup on problems that map reasonably well to GPUs, but quantum computing enables us to solve a class of problems that decades of advances in conventional computing could not.
A quantum computer is not a faster version of a conventional Turing machine - it uses different physical principles in a fundamentally different way, in order to solve a specific type of problem that's not practical to solve using linear approaches.
