Dilated RNN wave functions induce power-law correlations for the critical 1D transverse-field Ising model and the Cluster state, unlike the exponential decay of conventional RNN ansatze.
Covariant holographic entanglement entropy determines bulk radial geometry in stationary homogeneous 3D spacetimes when reconstructions from fixed-kappa families agree on a common radial coordinate.
Light cone cancellation decomposes VQE circuits for Max-Cut into smaller subcircuits, yielding higher approximation ratios on simulated noisy backends up to 100 qubits compared to standard VQE.
QCNN, QRNN, and QViT perform well on low-feature data but degrade on high-feature datasets, with QViT most robust to quantum noise and classical-style models better against adversarial noise.
