Application of quantum imaging in biology In biology, one of the main challenges is achieving a balance between high precision and minimal invasiveness in measurements. With cutting-edge techniques, the primary limitations to experimental accuracy often stem not from device-related noise but from fundamental physical constraints. Since nature is the underlying source of these constraints, it makes sense to go to quantum mechanics, the most basic theory of matter, for a solution. Improved measurement performance may be possible through the application of quantum effects, particularly those pertaining to coherence. It offers useful tools that, at the very least, offer interesting technical solutions even when they don't fully display cohesive behaviors. One of the primary applications of quantum technologies is quantum metrology, which uses the non-classical state of light to measure physical properties with great resolution and sensitivity. For biological applications, the quantum state of light may be utilized for precision enhancement and quantum noise reduction. This explains how quantum metrology, and particularly quantum imaging, can be used to enhance picture quality, measure shifts in quantum scales in biological systems, and boost imaging precision and resolution using quantum light sources, devices, and protocols. In this study, we give a summary of the possible uses of quantum technology in biology and medicine. This review presents a comprehensive overview of how quantum technologies can be applied in biology and medicine. It also explores the latest developments in quantum biological imaging, quantum microscopy, and quantum materials, while discussing the challenges and opportunities these emerging technologies bring.
Quantum metrology provides a route to overcome practical limits in sensing devices. It holds particular relevance to biology, where sensitivity and resolution constraints restrict applications both in fundamental biophysics and in medicine. Here, we review quantum metrology from this biological context, focusing on optical techniques due to their particular relevance for biological imaging, sensing, and stimulation. Our understanding of quantum mechanics has already enabled important applications in biology, including positron emission tomography (PET) with entangled photons, magnetic resonance imaging (MRI) using nuclear magnetic resonance, and bio-magnetic imaging with superconducting quantum interference devices (SQUIDs). In quantum metrology an even greater range of applications arise from the ability to not just understand, but to engineer, coherence and correlations at the quantum level. In the past few years, quite dramatic progress has been seen in applying these ideas into biological systems. Capabilities that have been demonstrated include enhanced sensitivity and resolution, immunity to imaging artifacts and technical noise, and characterization of the biological response to light at the single-photon level. New quantum measurement techniques offer even greater promise, raising the prospect for improved multi-photon microscopy and magnetic imaging, among many other possible applications. Realization of this potential will require cross-disciplinary input from researchers in both biology and quantum physics. In this review we seek to communicate the developments of quantum metrology in a way that is accessible to biologists and biophysicists, while providing sufficient detail to allow the interested reader to obtain a solid understanding of the field. We further seek to introduce quantum physicists to some of the central challenges of optical measurements in biological science.
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.
Abstract Quantum technologies leverage the laws of quantum physics to achieve performance advantages in applications ranging from computing to communications and sensing. They have been proposed to have a range of applications in biological science. This includes better microscopes and biosensors, improved simulations of molecular processes, and new capabilities to control the behavior of biomolecules and chemical reactions. Quantum effects are also predicted, with much debate, to have functional benefits in biology, for instance, allowing more efficient energy transport and improving the rate of enzyme catalysis. Conversely, the robustness of biological systems to disorder from their environment has led to proposals to use them as components within quantum technologies, for instance as light sources for quantum communication systems. Together, this breadth of prospective applications at the interface of quantum and biological science suggests that quantum physics will play an important role in stimulating future biotechnological advances. This review aims to provide an overview of this emerging field of quantum biotechnology, introducing current capabilities, future prospects, and potential areas of impact. The review is written to be accessible to the non‐expert and focuses on the four key areas of quantum‐enabled sensing, quantum‐enabled imaging, quantum biomolecular control, and quantum effects in biology.

Quantum sensors emerged among quantum technologies as the ones with promising potential applications in the near future. This perspective reviews two leading quantum sensing platforms and their advancements toward biological applications: quantum light sources and color centers in diamonds. Quantum light, including squeezed states and N00N states, allows enhanced phase measurements by surpassing the classical shot noise limits. This advantage can be exploited in several contexts, enabling improved resolution and sensitivity, which are particularly valuable in biological contexts where traditional high-intensity illumination could damage or alter delicate samples. In parallel, color centers in diamonds, specifically nitrogen-vacancy and silicon-vacancy centers, also emerged as promising for sensing applications due to their high sensitivity and biocompatibility. These sensors enable detailed intracellular measurements, such as temperature detection, and show potential for measuring magnetic fields of biological origin. Despite these advancements, significant challenges remain in translating these technologies from a controlled laboratory environment to practical, widely applicable devices for diverse biological applications. Overcoming these challenges is crucial for unlocking the full potential of quantum sensors in the biological field.
