In a groundbreaking discovery, researchers at the University of Strathclyde, in collaboration with Italian scientists, have harnessed the power of quantum light to revolutionize medical imaging and spectroscopy. This advancement, published in Science Advances, promises to significantly improve the sensitivity and capabilities of these vital medical tools.
The team discovered that entangled photon pairs can amplify two-photon processes, which are essential for biomedical applications. This allows for quantum enhancement at light intensity levels almost ten times higher than previously achievable, overcoming the limitations of traditional methods that often damage samples.
"Our research could lay the groundwork for the next generation of quantum-enhanced sensing approaches," said Dr. Lucia Caspani, lead researcher. This builds on previous work, including a 2023 European Research Council grant of nearly €2 million, aimed at developing enhanced 3D imaging through quantum entanglement. The QuNim project, spanning five years, seeks to achieve deeper imaging capabilities.
