Comment on How we get to 1 nanometer chips and beyond
Buffalox@lemmy.world 1 day agoWell in the future light may be possible, 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 ?

No no, quantum computing is more about using the quantum properties of particles to do computing in ways that you simply can’t with traditional computers. If you write your program to accommodate this kind of computing, you can essentially design programs to test all possibilities simultaneously - a pretty neat trick.
Right now we’re talking about photonic computing, simply using photons as the circuitry within a processor rather than electronic circuits using elections.
Though I’m not an expert on either, so I’m probably the wrong person to ask for more information on the subject.
