Metasurface_Mediated Entanglement_A GUR_Guided

Metasurface-Mediated Entanglement: A GUR-Guided Stress-Gate Approach demonstrates how engineered optical metasurfaces can exert precise, on-chip control over photon entanglement by leveraging the Gravitational-Memory-Ridge (GUR) collapse framework. The authors show that asymmetric, epsilon-near-zero (ENZ) metasurfaces naturally approach the GUR “handshake-stress” threshold, risking premature collapse of the quantum state. To prevent this, they introduce a five-step z-management protocol—mapping, segmentation, smoothing, pre-conditioning, and twin-peak verification—that keeps every interaction stage safely below the collapse gate. Building on recent advances in twisted-light rotation, cryo-EM pulsed-beam mitigation, and noise-enhanced quantum protocols, this work unites diverse photonic platforms under a single, scale-invariant collapse-gate prescription, paving the way for robust, ultrafast quantum photonic devices with built-in decoherence protection.
