Literally impossible and proven thus.

If you are not aware, Nimtz experiment is extremely cheap, relative to many scientific experiments of such significance. You could replicate it in your garage at weekend and measure superluminal speed of quantum tunneling just for fun.

Also, you could not prove impossibility. You only could proove opposite. It is Einshtein declared impossibility without any reason and in was Nimtz who proove opposite.
