Quantum Metrology

Quantum Metrology is a field that uses the principles of quantum mechanics to make highly precise measurements. It leverages phenomena like superposition and entanglement found in quantum systems, such as photons or atoms, to enhance measurement accuracy beyond classical limits. In quantum optics, this often involves using quantum light sources to test and measure properties of light or other physical quantities. The techniques developed in quantum metrology have important applications in various fields, including navigation, fundamental physics, and developing new technologies like sensors and clocks with unprecedented precision.
