To map the classical transition kernels of conscious agents to quantum physics, we explicitly derive the emergence of classical objectivity via Quantum Darwinism. We model the central agent $S$ and an environment partitioned into multiple fragments $E_F$. We define a dominant system Hamiltonian and a pure dephasing interaction $H_{int} \propto \sigma_S^z \otimes \sigma_{E_k}^z$ that commutes with the pointer basis. We derive the specific Lindblad jump operators $L \propto \sigma_S^z$. We then explicitly calculate the Mutual Information $I(S; E_F)$ across multiple environmental fragments. By demonstrating that the Holevo bound is saturated for multiple independent sub-baths, we prove that redundant copies of the system's pointer state are imprinted into the environment. This redundancy rigorously defines the emergence of the classical, objective Markovian networks utilized in Conscious Realism.
Classical objective states do not just emerge from generic decoherence; they emerge from the redundant proliferation of information into environmental fragments (Quantum Darwinism).
Let the system $S$ have a dominant Hamiltonian $H_S = \frac{\omega_0}{2} \sigma_S^z$.
To preserve the pointer basis against environmental scrambling, the interaction Hamiltonian must commute with $H_S$. We define a pure dephasing interaction:
Applying the Born-Markov and secular approximations, the resulting Lindblad jump operator is strictly pure dephasing: $L \propto \sigma_S^z$. The $\sigma_S^z$ eigenstates form the robust pointer basis.
The environment $E$ is partitioned into disjoint fragments $E_F$. We evaluate the mutual information $I(S; E_F)$ between the central system and a fraction $f$ of the total environment.
The interaction $H_{int}$ deterministically entangles the pointer states of $S$ with the local states of $E_k$. The decoherence functional suppresses off-diagonal terms while redundantly copying the diagonal state information into multiple independent fragments $E_F$.
The mutual information scales as $I(S; E_F) \approx H(S)$ for a very small fraction $f$, saturating the Holevo bound. This proves that many independent observers can interdependently deduce the state of $S$ without disturbing it.
The classical Markov kernels of Conscious Realism emerge rigorously from pure dephasing interactions and the redundant proliferation of pointer state information across environmental fragments.
