Abstract

This review examines the recent theoretical framework proposed by Srichan (2026) on Entanglement-Weighted Operator Geometry (EWOG) as a mechanism for stabilizing quantum coherence in biological radical pairs, particularly in the MagLOV2 protein model for avian magnetoreception. The key postulate of EWOG is that entanglement entropy dynamically modifies the effective Hamiltonian through coupling with protein structural operators, leading to suppressed decoherence rates that align with experimental observations of microsecond coherence times. We highlight the hypotheses, methodology, and results from Srichan's comparative statistical analysis against standard Lindblad decoherence models, demonstrating decisive empirical support for EWOG via Akaike and Bayesian Information Criteria. Algebraic interpretations reveal EWOG as a state-dependent perturbation to the Hamiltonian, while geometric views frame it as an entanglement-modulated projection onto protein anisotropy. Secondary research contextualizes EWOG within broader quantum biology, including similar mechanisms like vibrational assistance and quantum Zeno effects in photosynthesis and magnetoreception.

Advanced Quantum Effects in Cell Biology and the Information Geometry of Biological Coherence (Volume II)

Syed Muntasir Mamun

This analysis addresses the critical decoherence paradox in quantum biology, where observed microsecond coherence times in living cells vastly exceed the nanosecond predictions of standard open quantum systems theory. The study synthesizes theoretical and empirical advancements, establishing that the information geometry of biological macromolecules provides the mechanism for long-lived quantum states, where cellular structures function as optimized topological constraints that actively harness environmental noise. Key theoretical frameworks integrated include the Quantum Fisher Information (QFI) metric, which quantifies biological coherence and sets absolute limits on sensory precision (e.g., avian magnetoreception), and the Entanglement-Weighted Operator Geometry (EWOG). EWOG is empirically validated to resolve the decoherence discrepancy by demonstrating that quantum entanglement dynamically modifies the effective Hamiltonian, achieving a calculated 58% suppression of decoherence in proteins like MagLOV2. Furthermore, the study applies Quantum Geometrical Molecular Dynamics (QGMD) to show that the non-Abelian quantum geometric tensor drives nonadiabatic enzymatic catalysis, enabling quantum mechanical tunneling to provide profound energetic advantages, such as reducing the required energy for proton transport in mitochondrial Complex I by over 55%.

Quantum Defense Technologies Reimagined: A Geometric, Fractal, and Information-Theoretic Assessment (Vol-I)

Syed Muntasir Mamun

This assessment challenges the prevailing classical, isolationist paradigm of defense quantum engineering, which regards quantum states as inherently fragile and susceptible to thermal decoherence. It introduces an active, topological, and biological framework by synthesizing quantum-biological mechanisms—such as the radical-pair mechanism for coherence stabilization—with advanced mathematical constructs. The methodology integrates Entanglement-Weighted Operator Geometry (EWOG), multi-parameter Topological Data Analysis (TDA) via G-LoG bi-filtration, Information Geometry on Fisher-Rao manifolds, and the spectral realization of Riemann zeta zeros. This synthesis constructs a blueprint for resilient, emergent informational manifolds capable of active decoherence suppression. The resulting hybrid architectures accelerate the timeline for mission-relevant quantum sensing, computing, and communications, providing a robust, noise-resistant foundation that can bypass current limitations outlined in reports like the Congressional Research Service Defense Primer.

Entanglement-Dependent Frequency Shifts Beyond Quantum Electrodynamics: Experimental Evidence from the SpinQ Platform

Chavis Srichan, Pobporn Danvirutai

We report an experimental investigation of frequency shifts in multipartite entangled quantum systems using a SpinQ-compatible quantum platform. By systematically varying the number of entangled qubits $N$ while holding all geometric and electromagnetic parameters fixed, we test whether observed frequency shifts can be explained solely by quantum electrodynamics (QED), including the Lamb shift, or whether an additional entanglement-dependent contribution is required. We formulate and compare two competing models: a QED-only model predicting an $N$ -independent shift, and a QED+EWOG model incorporating an entanglement-weighted correction motivated by Entanglement-Weighted Operator Gravity (EWOG). Rigorous statistical analysis---using root-mean-square error (RMSE), coefficient of determination ( $R^2$ ), residual diagnostics, and the Akaike Information Criterion (AIC)---demonstrates decisive evidence in favor of the EWOG extension. Our results provide quantitative experimental support for the hypothesis that multipartite entanglement induces an effective geometric correction to coherent quantum dynamics beyond standard QED.We report an experimental investigation of frequency shifts in multipartite entangled quantum systems using a SpinQ-compatible quantum platform.

Algebraic Sectorisation, Information Geometry, and the Quantum-Classical Transition A Synthesis of the Anatomical Reviews (Vol-VI)

Syed Muntasir Mamun

This paper synthesizes the "Anatomical Reviews" to redefine the quantum-classical transition through an intrinsic operator-algebraic framework. It moves away from standard environment-induced decoherence toward a model where classicality emerges from the sectorisation of infinite-dimensional Hilbert spaces within isolated systems. Utilizing the Avalanche Photodiode (APD) model, the study demonstrates that macroscopic definiteness arises from double-exponential divergence in state overlap, creating a rigorous structural transition. The work formalizes this transition as a geometric degeneracy in the quantum Fisher information metric, linking fractal avalanche geometry to Tomita-Takesaki modular theory and providing a falsifiable experimental foundation for the algebraic Heisenberg cut.
