A study published in the international journal Biomedical Optics Express comprehensively demonstrates the potential of quantum imaging techniques using entangled photons to simultaneously achieve minimal invasiveness (non-destructiveness) and extreme precision when observing biological specimens. It argues that illuminating biological specimens with non-classical states of light, such as entangled photon pairs, can physically block uncorrelated classical background noise and exponentially improve the signal-to-noise ratio (SNR). By utilizing quantum correlations and squeezed light states, it transcends the diffraction limit of conventional optical systems, offering unprecedented resolution to visualize delicate biological structures in their natural state. [Quantum Biology Society] Achieving a perfect balance between minimal invasiveness and extreme precision in biological measurements has long been a challenge in the scientific community. Conventional classical optical imaging techniques required intense illumination to obtain high resolution, which inevitably led to cellular damage and ran into the barrier of physical diffraction limits. A recent study published in the international journal Biomedical Optics Express, titled "Application of quantum imaging in biology," comprehensively highlights how quantum imaging technology based on non-classical light breaks through these classical limitations. A joint research team consisting of Hoda Lotfipour, Hassan Sobhani, Mohamad Taghi Dejpasand, and Morteza Sasani Ghamsari from the Photonics and Quantum Technologies Research School at the Nuclear Science and Technology Research Institute (NSTRI) in Tehran, Iran, published this disruptive review study. ■ Quantum Entanglement Perfectly Blocking Noise The researchers focused on the potential of quantum metrology, which introduces non-classical states of light—particularly methods utilizing entangled photon pairs—into biological imaging. When extremely delicate and fragile biological specimens are illuminated with light in entangled quantum states, significant signals can be precisely sorted out through the strong quantum correlations between photons. Through this process, classical background noise that occurs randomly and independently of the entanglement state is physically blocked, ultimately leading to a remarkable, exponential improvement in the system's signal-to-noise ratio (SNR). ■ Extreme Resolution Without Destructive Sampling This innovative, non-invasive quantum microscopy technique opens the path to visualizing living organisms in their natural state without burning or damaging specimens with intense light energy. Furthermore, by actively exploiting quantum correlations and squeezed light states, it easily surpasses the diffraction limits and shot-noise limits of conventional microscopes, making it possible to observe the minute dynamics of intermolecular interactions. This study eloquently demonstrates that quantum imaging technology, which provides unprecedented ultra-high resolution without the risk of destructive sampling, is the core key that will fundamentally shift the paradigm of next-generation biology and precision medicine research. #QuantumImaging #BiologicalImaging #QuantumEntanglement #NonInvasiveImaging #QuantumMicroscopy #PhotonEntanglement #OvercomingNoiseLimits #QuantumBiology #Biophysics #KoreanQuantumBiologySociety https://pmc.ncbi.nlm.nih.gov/articles/PMC12339294/
