The penetration of quantum concepts into biological science, which began shortly after the creation of quantum mechanics, over the past two decades has taken shape in a new interdisciplinary scientific discipline quantum biology. One of the key questions of quantum biology has been formulated as follows: are there biological systems that use quantum effects to perform a task that cannot be done classically? More broadly, do some kinds of organisms adapt efficient quantum mechanisms in the process of their evolutionary development in order to gain an advantage over their competitors? The range of topical problems of the new discipline discussed in this brief review includes questions of a general, historical and methodological character, and generalizes some theoretical models aimed at describing quantum processes, including bacterialphotosynthesis, bird magnetoreception, and the mechanism of olfactory sense in living organisms.

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.

Quantum life science is a rapidly developing interdisciplinary domain that combines concepts from quantum physics with biological sciences to investigate the underlying mechanisms of living systems at the molecular and cellular levels. The principles of quantum mechanics, including quantum tunneling, superposition, and entanglement, are believed to contribute to various biological processes and may help explain phenomena that cannot be fully understood through classical biological models. Studying these quantum effects in living organisms remains difficult because biological environments are highly dynamic and are affected by factors such as decoherence and energy dissipation, which can mask quantum behavior. To overcome these limitations, researchers are employing sophisticated tools and methodologies such as biological nano-scale quantum sensors, quantum-enhanced hyperpolarized MRI and NMR techniques, ultrafast two-dimensional electronic spectroscopy, and advanced computational modeling. The integration of these technologies is accelerating progress in quantum biology and related disciplines. As the field continues to evolve, it offers promising opportunities for advancing knowledge in genetics, molecular biology, medicine, biotechnology, and bioengineering, potentially leading to innovative diagnostic and therapeutic applications.
Quantum biology is the study of quantum effects on biochemical mechanisms and biological function. Quantum physics describes the behaviour of the nanoscale particles that make up all matter including living organisms, but it was generally believed that the ‘warm, wet and noisy environment’ in living organisms would result in decoherence making it impossible for meaningful quantum effects to occur. However, there is now a substantial body of work supporting that nature has actually adapted in such a way as to exploit quantum properties to enhance cellular functioning and is believed to have role in a diverse range of key processes in living organisms ranging from maintaining the stability of DNA to neuron function to conscious cognition; from light harvesting in photosynthesis to avian magnetic field based navigation. This review aims to summarize the various mechanisms and functions in living organisms believed to utilize quantum mechanics to purposefully and effectively enhance their performance, and to explore the potential this could hold in diagnosing and treating various medical conditions.
Quantum physics and biology have long been regarded as unrelated disciplines, describing nature at the inanimate microlevel on the one hand and living species on the other hand. Over the past decades the life sciences have succeeded in providing ever more and refined explanations of macroscopic phenomena that were based on an improved understanding of molecular structures and mechanisms. Simultaneously, quantum physics, originally rooted in a world-view of quantum coherences, entanglement, and other nonclassical effects, has been heading toward systems of increasing complexity. The present perspective article shall serve as a "pedestrian guide" to the growing interconnections between the two fields. We recapitulate the generic and sometimes unintuitive characteristics of quantum physics and point to a number of applications in the life sciences. We discuss our criteria for a future "quantum biology," its current status, recent experimental progress, and also the restrictions that nature imposes on bold extrapolations of quantum theory to macroscopic phenomena.
Quantum biology is an innovative field that blends quantum mechanics and biology to explore how quantum phenomena influence biological processes. This review discusses the fundamental principles of quantum biology, its potential applications in medicine, materials science and energy production, as well as the ethical implications of its progress. By understanding the quantum intricacies of life, we can gain insights into disease mechanisms, develop innovative materials and harness sustainable energy sources. Quantum mechanics, essential for understanding atomic and subatomic behavior, underpins quantum biology, which examines processes like photosynthesis, olfaction and enzyme catalysis. Key principles include superposition, entanglement and tunneling, which may enhance biological efficiency, sensitivity and precision. Quantum biology’s potential spans various fields: in medicine and pharmacy, it could lead to new diagnostic tools and therapies; in materials science, it could inspire quantum materials for electronics, energy storage and sensing; in energy production, it could inform sustainable energy development through photosynthesis insights. However, ethical considerations are crucial. Quantum-enhanced medical technologies might widen healthcare disparities and advanced quantum materials could have mixed societal impacts. Open dialogue and ethical frameworks are necessary for responsible development. The future of quantum biology is promising, with ongoing research and interdisciplinary collaboration expected to yield innovative discoveries, fostering a sustainable and prosperous future.

This paper presents a historical overview of quantum physics methodology's development and application to various science fields beyond physics, especially biology and consciousness. Following a successful interpretation of several early 20th century experiments, quantum physics gradually provided a conceptual framework for molecular bonds via quantum chemistry. In recent years individual biological phenomena such as photosynthesis and bird navigation have been experimentally and theoretically analyzed using quantum methods, building conceptual foundations for quantum physics' entry into biology. Quantum concepts have also been recently employed to explain physiology's allometric scaling laws by introducing quantum metabolism theory. In the second part of this work, we discuss how quantum physics may also be pivotal to our understanding of consciousness, which has been touted by some researchers as the last frontier of modern science. Others believe that consciousness does not belong within the realm of science at all. Several hypotheses, especially the Orch OR theory, have been suggested over the past two decades to introduce a scientific basis to consciousness theory. We discuss the merits and potential extensions of these approaches.
