Microscopic AMDCF Modeling of Two-Qubit Entanglement Sudden Death and Non-Markovian Revival

Building upon the unified Adaptive Memory-Driven Coupling Framework (AMDCF) computational kernel, we extend the model to simulate multi-qubit entanglement networks. Using a 4-qubit system (yielding 6 pairwise entanglement channels) as a testbed, we demonstrate that standard Markovian decoherence leads to complete network concurrence decay. In contrast, by applying the AMDCF exact memory backflow and a network-level adaptive safety valve, the system successfully retains a stable concurrence across all pairs. Simulation results show that while uncontrolled channels collapse to a mean concurrence of 0.0107, the AMDCF-protected network stabilizes at 0.5650. This demonstrates that the AMDCF kernel scales efficiently to high-dimensional quantum networks, offering a robust algorithmic control mechanism against environmental crosstalk and decoherence.
