Well in the future light may be a possibility, and light is merely a photon, and you can have photons basically follow the same paths in each direction simultaneously without colliding.
So without in any way being an expert, I would think that if light can somehow be controlled precisely enough, that would be a possibility to go way below what any atom can. Even if the paths need to be directed by atoms.
But AFAIK there is not a practical working model for that yet, although research on it has been going on for decades.

I see. Isn’t this more or less the premise of quantum computing ?
