Quantum Earth

"Some things are literally impossible. Everything else is merely improbable, to varying degrees."
Lucas Winter, lawnmower man, was happy. With his life, that is. Not so much with the state of the world, but was pragmatic enough to recognise that there was nothing one man could do about that. Until a highly improbable series of events gave him the opportunity to make a significant difference.
Quantum computing was the holy grail of computing science, and a laboratory in Spain was nearing a breakthrough, but when something went wrong with their final experiment, a young man in a farmhouse on the other side of the world was the unsuspecting recipient of their years of research. With the help of the powerful computer now in his control, Lucas set about making the world a better place, though not everyone would see it that way.
