Caltech Researchers Enhance Microscope Resolution Fourfold Using Quantum Optics

Caltech scientists have developed a novel quantum optical setup that quadruples the resolution of a light microscope, building on prior work. This advancement, published in Science Advances, sends entangled photons through the microscope's optics multiple times to achieve the enhancement. The technique has significant implications for low-light biomedical imaging, potentially allowing clearer visualization of fine cellular structures without causing damage.
