Note that this requires a Quantum Many Worlds, but if that's a
wrong assumption, you'll probably only lose the price of one
ticket. Big deal!
Step 1. Design a scheme for making a lottery number out of
arbitrary data. You should work from a domain much bigger than the
lottery number codomain space, and it should be a surjective
mapping.
Step 2. Get a bunch of quantum generated random data. Let it
perturb your behaviour in more ways than just the ticket number.
Step 3. Buy a lottery ticket.
Step 4. Futures that win: Celebrate and do whatever. Futures
that lose: Never ever gamble at a disadvantage, ever again.
