Fixing the Quantum Delusion
Why quantum substrates amplify geometric instability rather than resolve it
Fixing the Quantum Delusion argues that quantum computing does not solve frontier‑AI instability because instability arises from geometry, not compute. As the paper states, “A change in substrate does not guarantee a change in geometry.” Quantum systems expand amplitude and throughput but do not strengthen the manifold structures models must inhabit. Instead, quantum dynamics — superposition, interference, decoherence — introduce fragile geometric behaviour that amplifies drift, deformation, and instability already present in classical models.
The paper shows that embedding quantum components into unstable classical geometries produces coupled drift, decoherence cascades, and multiplicative failure modes. Quantum feature spaces, though exponentially large, are exponentially sensitive, with stability regions shrinking as dimensionality grows. The core conclusion is structural: quantum accelerates the dynamics that destabilise frontier AI but does not reinforce the geometry required for coherent reasoning. Stability cannot be outsourced to physics; it must be governed by explicit geometric mechanisms such as Clarus..
