Survival probability maps for any nontrivial pair of unitaries cannot achieve point-wise complementary correlation over the full projective state space, imposing a unitary-geometric limit on anti-contrast.
QCNNs are classically simulable via Pauli shadows on low-bodyness subspaces of locally-easy datasets, with explicit simulation demonstrated up to 1024 qubits for phases of matter classification.
