Is there anything in particle physics that emulates the processing

Theoretically, you can emulate a universal computer with billiard
balls, on an infinite table. I think that classical physics needs
three bodies to emulate a universal machine. QM needs 0 bodies, as
the quantum vacuum is already Turing Universal, and even emulates
"naturally" a universal quantum dovetailer (making it into a
possible comp measure winner).
Just three? Wow!
I think. Not yet seen a proof, but I think 3 bodies are enough.
(I assume it also needs no friction, perfectly elastic collisions
and what-have-you?)
Yes, sure.
