Quantum Optical Metrology

Quantum optical metrology uses principles of quantum physics—such as entanglement and superposition—to measure physical quantities like distance, time, or gravitational fields with extremely high precision. By manipulating and detecting light at the quantum level, scientists can surpass the limitations of classical methods, achieving more sensitive measurements. This approach is vital in advancing technologies like ultraprecise sensors, gravitational wave detectors, and quantum imaging, enabling breakthroughs in scientific research and practical applications where tiny changes must be detected accurately.
