What exists is a weird engineering experiment that runs some synthetic tests that are designed to return a number that you plot on a graph which you show your investors. And it costs all the money in the world and then some.
Not only there is no practical use for all that, there are debates about what the practical uses might even be in theory for something that nobody really sure is happening.
