Integrating quantum mechanics into cybersecurity frameworks offers transformative opportunities for addressing sophisticated digital threats. The Quantum-Infused Multi-Dimensional Signal Convergence (QIMDSC) framework introduced a pioneering methodology that leverages quantum principles for detecting highly dynamic and obfuscated ransomware behaviors. By encoding behavioral patterns into enriched quantum states and analyzing signal convergence through multidimensional mathematical constructs, the framework achieved significant advances in detection accuracy and computational efficiency. Comprehensive experiments demonstrated its ability to minimize false positives while maintaining high recall rates across diverse ransomware families, including LockBit, Hive, and BlackCat. Comparative analyses demonstrated the framework's superiority over traditional machine learning-based and hybrid approaches, particularly in identifying zero-day ransomware variants. The introduction of probabilistic wavefunction modeling further refined the detection mechanism, enabling the isolation of subtle deviations within high-dimensional feature spaces. Real-time anomaly detection capabilities were validated through extensive simulations, where the framework consistently performed well under varying network and system loads. Its ability to adapt to encryption depth and respond effectively to large-scale ransomware activity emphasizes its robustness in dynamic environments. The scalability of the architecture and its reliance on modular design ensured applicability across critical infrastructure, enterprise networks, and resource-constrained systems. Performance evaluations revealed that the framework excelled under conditions of high file system activity and network variability, demonstrating exceptional resilience to operational noise. The innovative approach bridges theoretical quantum mechanics with practical cybersecurity applications, marking a paradigm shift in threat detection methodologies. Insights derived from this research highlight the potential of quantum-inspired techniques for addressing emerging challenges in modern cybersecurity landscapes.
