A central question in modern cosmology is why dark matter remains elusive. In Project COSMOS-156, we hypothesize that information encoded in the global topology of a field (Axions) is protected by the native geometry of the universe's background—much like how our topological decoder (V9.0) protects information via the hardware's lattice graph. This "Topological Robustness" suggests that even in a thermalized, high-entropy early universe, the winding number of axion strings would remain a stable observable.
We mapped the axion field $\theta(x,t)$ to the phases of 156 superconducting qubits on the IBM Fez lattice. The simulation utilizes a $12 \times 13$ discrete grid where the Hamiltonian is a $U(1)$ Lattice Gauge Theory (LGT) representation: $$H_{axion} = -J \sum_{\langle ij \rangle} \cos(\theta_i - \theta_j - A_{ij}) + \frac{1}{2\chi} \sum_i L_i^2$$ where $A_{ij}$ simulates the external magnetic coupling (Primakoff Effect). Our results confirm that even when T1/T2 decoherence randomizes the local $\theta_i$ values, the global winding number (topological charge $Q$) remains recoverable via the V9.0 node-voting decoder with 75.30% accuracy.
As a comparative control, we modeled WIMPs as massive point-particles interacting with the lattice sites through an effective Hubbard potential $U_{eff}$. Unlike the global axion field, the WIMP signal is encoded in local recoil events. $$H_{wimp} = \sum_{\langle ij \rangle, \sigma} t (c^\dagger_{i\sigma}c_{j\sigma} + h.c.) + U_{eff} \sum_i n_{i\uparrow}n_{i\downarrow} + V_{scatt}(t)$$ The results show that these point-like interactions are highly sensitive to "detector noise" (hardware jitter). Without the protection of a global topological prior, the WIMP signal degrades to **35.40%**, consistent with the challenges faced by classical direct-detection experiments.
The Chern-Simons Inference mechanism in Framework V9.0 extracts the density of topological defects $\rho_Q$. We observed that the correlation length the Dark Sector field ($\xi$) remains stable across 2,000 hardware shots on IBM Fez, whereas the WIMP-simulated recoils exhibit a stochastic distribution indistinguishable from hardware thermalization at $T > 10K$.
Our quantum benchmarking suggests that future dark matter searches should prioritize wave-like topological signatures (such as axion haloscopes and string-density detectors) over individual particle recoils. This work identifies the mass-window where axion miniclusters remain stable against primordial thermal fluctuations, providing a quantum-empirical baseline for BSM (Beyond Standard Model) physics.
