Quantum mechanics as a theory of information

Spread the love

From Atlantic:

But even if quantum nonlocality is the best we can hope for, PR boxes may offer clues about why that is. The question becomes not so much why nature isn’t completely classical, but why it’s not “more” quantum. We should then seek answers not by wondering why, say, objects are described by wave functions (or what a wave function is anyway), but by looking at a more fundamental matter of how information can be shunted about—of how efficient communication in nature can possibly be. What is it that apparently limits quantum nonlocality’s ability to make information exchange more efficient?

All this fits with a growing conviction among many physicists that quantum mechanics is at root a theory not of tiny particles, but of information. It’s about how much we can deduce about the world by looking at it, and how that depends on intimate, invisible connections between here and there.More.

    I take that back. It’s about space.

    I just gave they atheists a piece of my mind ! They published it, then very speedily removed it.

    After censuring them for not considering Planck’s opinion that atoms and particles are held in orbit by a divine matrix of forces and a massive intelligence, i.e. God, I then informed them that we would still be waiting to discover quantum theory, if we had had to rely on the open-mindedness(!) of atheists.
