Just a comment for clarification. In quantum statistical mechanics
density matrix is statistical description of ensemble. In TGD inspired
theory of consciousness it is descriptio of single subsystem: quantum
statistical density matrix could be regarded as ensemble average of this
density matrix.
The dimension of density matrix in TGD sense is determined by the number
N of entangled states, which also measures the 'resolution' of quantum
measurement and also maximum 'catchiness' of conscious experience since
maximum negentropy gain is log(N) in real context.
