Photons can re-combine? So they are unlike electrons or positrons, which like a
magnet, repell like charges. Based on your description, Liz, then somewhere in
the universe, are glowing soft-white piles of Photonium? Ah! The creamy nougat
center of every barred spiral galaxy!

</div>The "physical system" refers to all parallel instantiations of an
object ISTM.
If I refer to a photon travelling through a ZM apparatus (to fix
things - you know two half silvered mirrors, so the photons are split
and travel over two spatially disinct paths before being recombined),
we don't have two different physical systems in play. Its just
the one physical system, even though it occupies two distinct universes.

The difference is that the photons
<i>can</i> recombine, hence their states in different branches have a
physical influence no the final outcome. But the processes leading to
conciousness can't, normally, reconmbine, because brain-stuff decoheres far
more rapidly than the timescales on which consciousness takes place. Hence
counterfactuals aren't involved in consciousness, at least not ifwe assume
consciousness supervenes on a physical system obeying QM.
