Entropy-Induced Collapse (EIC) Model – Part 2: Bridging Quantum Error Correction, Non-Markovian Dynamics, and Comparative Analysis with Gravity-Based Collapse Theories

This paper presents a rigorous refinement of the Entropy-Induced Collapse (EIC) model, a novel thermodynamic approach to quantum measurement theory. The EIC model hypothesizes that wavefunction collapse occurs when environmental entropy, quantified via von Neumann entropy, exceeds a dynamically evolving threshold. This extended framework systematically integrates quantum error correction (QEC) and non-Markovian noise, using fractional Brownian motion (fBm) to model realistic environmental correlations. Analytical derivations for the entropy threshold shift under QEC, combined with high-performance simulations and empirical validation on current quantum hardware, provide strong support for the model’s predictions. Comparative analysis with gravity-based (Penrose–Diósi), spontaneous collapse (GRW/CSL), and conventional decoherence theories demonstrates that the EIC model uniquely explains experimentally observed coherence times and error rates, particularly in scalable, small-mass quantum devices. This work offers a testable, physically grounded alternative to legacy collapse models, with practical relevance for quantum computing and foundational physics.
