My point was that if there is a record that a measurement was made,
something irreversible has been extracted from the experiment. If
the QC is "conscious", then it has to interact with something to
make this irreversible record, so its quantum state is irreversibly
changed. But you are probably right: if there is no decoherence,
then there is no consciousness, since consciousness involves
irreversible memory.
There are experiments already performed in which the welcher weg is
available but is erased, even spacelike relative to detection
I know. But no information was extracted from the welcher weg photons
before they were erased. I.e., no consciousness "recorded" which way
and then forgot the result. I think the act of recording the result,
by a consciousness or anything else, is inherently irreversible. If no
record is made, then erasure is perfectly possible. Just knowing that
there were welcher weg photons that have been erased is not quite the
same thing.
But that's my question: Why isn't it the same? And even if it's not how
would be know? The "conscious" quantum computer assures us that it not
only detected that there was a welcher weg photon but that it's weg was
known to the "consciousness" of the quantum computer, before it was
erased. But why would we believe it? We already have these experiments
in which we know the weg was available and could have been recorded, but
was erased. So what is the "consciousness" that adds a secret-sauce to
the experiment?
