Active Quantum Error Control via the AMDCF Framework: A Lightweight Feedback Approach to Decoherence Suppression

This paper introduces a novel application of the Adaptive Memory-Driven Coupling Framework (AMDCF) as an active feedback control system for open quantum systems. Unlike traditional quantum error correction (QEC) protocols that require massive hardware overhead and auxiliary qubits, we propose a lightweight, mathematically driven feedback mechanism based on the AMDCF dynamic safety valve. By continuously monitoring the quantum fidelity and applying nonlinear suppression via the tanh function, the system successfully counteracts environmental noise. Numerical simulations demonstrate that the AMDCF-controlled state maintains a high level of coherence (stabilizing around Fidelity ~ 0.7) over time, preventing the complete decoherence observed in uncontrolled systems. This framework offers a promising new pathway for designing decoherence-resilient quantum architectures.
