Quantum metrology is one of the pillars of quantum technologies. It shows how one can use quantum effects, such as entanglement and squeezing, to increase the precision of the measurements one can do. It also establishes the ultimate bounds, on precision that any measurement can achieve, e.g. through the Heisenberg uncertainty relations and the quantum speed limits.
