This work presents an exploratory conceptual analysis of the possible biophysical implications of fundamental coherence limits arising from gravitational time dilation. The objective is to investigate, at a phenomenological level, whether complex biological processes can operate in regimes sensitive to decoherence mechanisms already predicted by relativistic quantum theory. The study builds upon results established by Pikovski et al. regarding time dilation-induced decoherence, utilizing them exclusively as a background physical limit. No modification or extension of this formalism is proposed. The contribution of the present work consists of examining how such limits might be operationally relevant in the description of non-equilibrium molecular systems, particularly in enzymatic contexts and intracellular dynamics. In this context, we introduce the notion of spectral modulation of the internal energy variance ($\Delta E$) as an effective parameter to experimentally test the functional sensitivity of biological systems to these physical limits. The hypothesis is formulated in a falsifiable manner, with suggestions for verification based on time-resolved spectroscopic and structural techniques. The manuscript has an exploratory and interdisciplinary character, situated at the interface between fundamental physics, biophysics, and molecular chemistry, and intends to serve as a starting point for further theoretical and experimental investigations, without claiming the existence of macroscopic quantum coherence in living systems.

This work investigates the biophysical implications of a fundamental limit already established in the literature at the interface between quantum mechanics and relativity, namely, the decoherence induced by time dilation in composite systems, formally derived by Pikovski et al. This effect demonstrates that, even in the absence of an external environment, differences in proper time couple the internal and external degrees of freedom of quantum systems, leading to a loss of interferometric coherence as a direct consequence of the relativistic structure of spacetime. The present study does not introduce modifications to this formalism nor proposes new decoherence mechanisms; it starts explicitly from these results as a background physical constraint. Our objective is distinct: to analyze complex molecular systems operating persistently in non-equilibrium regimes — notably biological systems — in light of this universal limit. We propose that biochemical functionality should not be described solely by structural or energetic criteria, as in the classical spatial affinity paradigm (“lock-and-key”), but also by the system's ability to maintain temporal compatibility between its internal modes during finite operational intervals. We term this operational regime the Simultaneity Window, characterizing a dynamic condition of effective coherence sustained by a continuous flow of free energy. In this framework, processes involving the loss of functional viability can be modeled as the transition of the molecular system to the intrinsic decoherence regime predicted by relativistic-quantum theory, occurring when the variance of internal energy (ΔE) exceeds the range compatible with the maintenance of this operational coherence. The notion introduced here does not alter the underlying physical mechanism but identifies a domain in which biochemical systems explore — and need to circumvent — such a limitation. Based on this operational interpretation, we introduce the concept of Chrono-Inhibitors: agents capable of modifying the internal spectral distribution of a target biological system, shifting it in a controlled manner into the effective decoherence regime without requiring direct structural modification. We operationally define a \emph{chrono-inhibitor} as any external perturbation capable of altering the internal spectral variance ΔE without directly modifying the system's average structure.
Abstract The lines separating Biology and Physics have started to blur in recent decades, leading to the emergence of the interdisciplinary field known as quantum Biology. This field looks into the possibility that basic quantum mechanical phenomena such as coherence, entanglement, tunneling, and superposition play crucial roles in biological processes that are beyond the scope of classical Physics. Biology has traditionally worked within the parameters of classical mechanics, presuming that delicate quantum effects cannot endure in the warm, humid, and cacophonous environments of living systems. But new findings in fields like photosynthesis, olfaction, avian magnetoreception, and enzyme catalysis indicate otherwise, suggesting that living things intentionally and possibly advantageously use quantum principles. From the earliest speculative theories to the most recent experimental confirmations, this book chapter methodically examines the evolution of quantum Biology. We investigate how the exceptionally high energy transfer efficiency in photosynthetic complexes particularly in the light-harvesting proteins of green sulfur bacteria and plants is supported by quantum coherence. The remarkable speed of proton transfers and enzymatic reactions during DNA replication is also investigated in relation to quantum tunneling. The chapter explores magnetoreception in migratory birds and suggests models in which sensitivity to Earth's geomagnetic field is made possible by radical pair mechanisms influenced by quantum entanglement. We also discuss the intriguing but controversial idea that quantum vibrations improve the human olfactory system's capacity for discrimination. In addition to examining particular occurrences, this research challenges more general theoretical models that seek to balance quantum mechanics with the decoherence commonly observed in biological settings. Recent developments in quantum information theory, biomimetic quantum technologies, and ultrafast spectroscopy are highlighted as essential instruments advancing empirical research. We also critically evaluate the field's methodological difficulties, the skepticism of overly optimistic interpretations, and the significant philosophical ramifications of acknowledging life as a quantum phenomenon. In conclusion, quantum Biology suggests that quantum effects are not uncommon aberrations but rather are an essential part of life, offering not only a fresh perspective for reinterpreting well-known biological processes but also the potential for a fundamental paradigm shift. Quantum biology has the potential to completely transform biotechnology, medicine, and our comprehension of consciousness and the origin of life as experimental methods advance. This chapter highlights the significance of interdisciplinary cooperation in order to completely comprehend the latest discoveries and possible future paths of quantum Biology, highlighting its revolutionary influence on our comprehension of life at the most basic levels.

Both quantum mechanics and general relativity are based on principles that defy our daily intuitions, such as time dilation, quantum interference and entanglement. Because the regimes where the two theories are typically tested are widely separated, their foundational principles are rarely jointly studied. Recent works have found that novel phenomena appear for quantum particles with an internal structure in the presence of time dilation, which can take place at low energies and in weak gravitational fields. Here we briefly review the effects of time dilation on quantum interference and generalize the results to a variety of systems. In addition, we provide an extended study of the basic principles of quantum theory and relativity that are of relevance for the effects and also address several questions that have been raised, such as the description in different reference frames, the role of the equivalence principle and the effective irreversibility of the decoherence. The manuscript clarifies some of the counterintuitive aspects arising when quantum phenomena and general relativistic effects are jointly considered.
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%.

The precise physical nature of information remains an open wound on the side of modern physics. While often treated as an abstract mathematical quantity, recent developments in the Mass-Energy-Information Equivalence Principle argue for a more material interpretation: that information carries finite mass. Parallel to this, the field of quantum biology has long wrestled with the possibility of macroscopic coherent states within living systems, most notably through the Orchestrated Objective Reduction hypothesis. This article offers a perspective that attempts to weld these two speculative frameworks into a single, testable prediction. We explore the speculative hypothesis that if biological systems indeed sustain macroscopic quantum coherence, their eventual decoherence must—according to information conservation principles—result in a physical massdefect. Unlike thermal dissipation, which is diffusive and slow, this ”information crash” should theoretically release a sharp, gravitationally detectable transient. Here, we outline the constraints of such an event and propose a conceptual protocol using near-field atom interferometry to isolate this signal from the thermal background. The goal of this perspective is to move the debate on biological information from philosophy into the realm of falsifiable experimental physics.
The existence of living organisms in the mesoscopic realm may be quite nontrivial and actuallymay emerge from the interplay between quantum mechanics and gravity. On one side, quantumbiology investigates how quantum mechanical phenomena, such as superposition, entanglement,and tunnelling, contribute to biological processes. These quantum effects, once thought to beirrelevant in the “warm, wet, and noisy” environment of living organisms due to decoherence, havebeen found to play significant roles in various biological systems, from photosynthesis to enzymecatalysis. On the other side, gravitational forces have been implicated in the organization ofmicrotubules, which are essential for maintaining cellular structure and function. Recent studieshave demonstrated that gravitational forces can induce three-dimensional chromosomal conformational changes, which are associated with rapid transcriptional responses in human T cells. Sometheories propose that gravity might play a role in decoherence, such as in the Penrose-Hameroffmodel, which proposes that quantum coherence in microtubules could be the basis for consciousawareness and quantum computing-like information processing, with gravity playing a role in thecollapse of the quantum wave function. The model predictions that microtubules can support longrange coherent phenomena have been confirmed by experimental observations of superradiancefrom mega-networks of tryptophan UV-excited transition dipoles, particularly in microtubulearchitectures. Another experimental research highlights that microtubule network exhibits ahierarchy of three-fold resonant frequency patterns across biological scales – from tubulin proteinsto microtubules and neurons. This suggests a quantum-to-classical transition governed by scalefree dynamics, potentially underlying information processing in the brain. A very intriguing fact isthat at the most fundamental level of the origin of life, the standard genetic code, we can observethe scale-free computing that arises from arithmetic regularities of the nucleon numbers related tothe code’s numerous symmetries. Given that some of these symmetries probably originate fromdifferent evolutionary epochs, such scale-free computing may be a latent background mechanismof the organization of the genetic code and therefore relevant to natural computing.
