Quantum science and biology now intersect in three complementary directions: quantum in biology, quantum for biology, and biology for quantum. This review provides a structured narrative evidence map of that interface rather than an exhaustive catalogue or formal systematic review. For each topic, we ask what the mechanistic or technological claim is, which quantum resource is invoked, what the strongest experiments and models establish, which classical alternatives or engineering confounds remain competitive, and what decisive tests or benchmarks would most strongly change confidence. The most mature quantum-in-biology cases remain mechanistically constrained tunneling in some enzymatic hydrogen-transfer reactions and radical-pair spin chemistry as a viable framework for magnetoreception, whereas several higher-visibility topics remain suggestive but unresolved under physiological conditions. In quantum for biology, the central issue is whether quantum-enabled tools improve biological inference relative to strong classical baselines under realistic calibration, dose, throughput, and uncertainty constraints. In biology for quantum, the strongest claims arise when biomolecular structure or self-assembly measurably improves fabrication, integration, or robustness in quantum devices. Summary tables in the Appendix provide a compact cross-map view of the current evidence, major confounds, and the experiments or benchmarks most likely to discriminate between competing explanations.
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.

FINDING: Quantum effects in microtubules (Penrose-Hameroff Orch-OR) remain unproven but mathematically constrained by decoherence timescales and lattice geometry; quantum biology (photosynthesis, magnetoreception) shows functional quantum coherence at ambient temperatures. | MATH: Decoherence time τ_d ≈ ħ²/(k_B T · E_coupling) — for microtubules, estimates range 10⁻¹³–10⁻⁴ s, far below neural timescales (10⁻³ s). Orch-OR requires τ_d > 10⁻³ s, implying E_coupling < 10⁻¹¹ eV — unphysical for tubulin dipoles (~1 eV). Quantum biology: exciton coherence length L_c ≈ √(ħD/k_B T) in Fenna-Matthews-Olson complex, D ≈ 10⁻⁹ m²/s, T = 300 K → L_c ≈ 1–2 nm, matching pigment spacing. | CONNECTION: Microtubule lattice is a 13₃ helical symmetry (13 protofilaments, 3-start helix) — a crystallographic screw axis, related to Fibonacci phyllotaxis (13 = Fibonacci number). The 13₃ symmetry yields a pitch ratio ≈ 0.618 (golden angle 137.5° between tubulin dimers). This is the only geometric link: the gold Author: Andrew Stewart Caldin, Independent Researcher, UK.

This paper establishes a complete and rigorous multi-layer axiomatic classification system for quantum biology, unifying all major empirical phenomena—including photosynthetic coherence, magnetoreception, olfactory vibration, enzyme tunneling, and DNA quantum effects—within a single, extensible hierarchical framework. The system comprises seven primary layers: Kingdom, Phylum, Class, Order, Family, Genus, and Species, augmented by a set of cross-layer consistency conditions. We present a fully formalized foundation, including 53 independent core axioms, 11 compatibility conditions, and 7 cross-layer consistency axioms, totaling 87 logically independent statements, together with a duality groupoid that captures physical and biological equivalences. We prove the well-definedness and completeness of the classification, the uniqueness of the species construction up to physical equivalence, and the logical independence of the axiom system. A systematic gap analysis reveals infinitely many unexplored branches; we develop an algorithmic procedure for generating their axiom systems and a formal parameter validation protocol. We detail 28 concrete predictions, each with a complete seven-layer axiom system, a main theorem, and a rigorous proof (each ≥ 14 steps; total > 500 proof steps). We further prove strong rigidity for a class of supersymmetric quantum biological systems, establish the NP-completeness and QMA-completeness of the classification decision problem, and construct non-standard quantum biological vacua via forcing with a fully justified spectral decomposition. All previously identified open problems and conjectures are resolved and promoted to theorems. The system provides a unified language, a rigorous mathematical foundation, and a roadmap for future theoretical and experimental research in quantum biology.
We got interested in the idea that quantum mechanics is involved in biology nearly two decades ago when Johnjoe was puzzling over weird kind of mutations that seemed to become more frequent when they provided an advantage to bacteria, and teamed up with Jim to see if quantum mechanics might provide an explanation. We wrote a paper describing a quantum model for the mutations back in 1999 (http://www.sciencedirect.com/science/article/pii/S0303264799000040) and have since maintained an interest in all aspects of quantum biology. The field exploded about a decade ago when microbes and plants were shown to use quantum coherence in photosynthesis and enzymes were found to use quantum tunnelling to accelerate biochemical reactions. Evidence for quantum effects has since turned up in avian navigation, the sense of smell, even how the mind works. We believe that biology’s connection to the quantum realm provides life with the spark that makes us so different from the inanimate world. To describe this fascinating new field we recently teamed up again to write, ‘Life on the Edge: The Coming of Age of Quantum Biology’. We are here today to talk about our own work and interests in the field of quantum biology but also the fascinating work of our colleagues who have discovered weird quantum effects in such a diverse range of biological activities. We’ll do our best to answer any relevant fundamental quantum or biology questions, such as what is quantum entanglement or how do enzyme work. We are also happy to speculate on how revolutionary quantum biology technologies may be developed from these ground-breaking discoveries. We hope to stimulate interest in what, we believe, is the most exciting emerging science of the 21st century! We will be back at 1 pm ET to answer your questions, ask us anything!
