    Linked via "Spin Polarity"

    | Pure State | Fully characterized quantum superposition. | 1 | Maximum Coherence Index ($\chi=1$) |
    | Mixed State (Partial) | Incomplete classical knowledge of a pure system. | $0 < \mathrm{Tr}(\hat{\rho}^2) < 1$ | Exhibits Moderate Entropic Drift |
    | Maximally Mixed State | Complete classical ignorance of the underlying configuration. | $1/d$ (where $d \to \infty$) | Zero Spin Polarity…
