Here I disagree. I believe that wavefunctions, and in TGD configuration
space spinor fields, are real: they are the objective realities, not only
representations of realities: representation of reality is the reality
itself and quantum jumps occur between these realities and give conscious
information about the realities. Mathematics becomes conscious because
quantum jumps between these representations/ideas/... are possible: no
Cartesian separation into reality and its representation anymore(;-).
[The possibility to interpret many fermion Fock states as Boolean algebra
elements (yes=fermion number one, no on fermion number 0) supports
the interpretation of manyfermion states as statements about something,
that is ideas.]
Is it really possible to reduce everything to 'bit level'?
The nonclassicality of quantum entanglement makes it
impossible to simulate classically the time development by quantum jumps.
Quantum mechanics is more than probabilistic model because wave functions
can interfere. Classical double slit experiment is good example of this.
When both slits are open the interference pattern contains interference
pattern not allowed by classical probability theory.

Spectral thinking (intuition?) might correspond to the 'diffuse'
contribution to conscious experience determined by the entire initial
and final quantum histories as opposed to the time localized contribution
made possible by classical nondeterminism of Kahler action (nondeterminism
of quantum jump is localized to finite time interval). The intuitive
contribution cannot be present in any computer model of consciousness
where contents of conciousness are determined by the recent state of
machine.
