Abstract
En 中文
The purpose of quantum technologies is to explore how quantum effects can improve on existing solu-tions for the treatment of information. Quantum photonics sensing holds great promise for reaching a more efficient trade-off between invasivity and quality of the measurement, when compared with the potential of classical means. This tutorial is dedicated to presenting how this advantage is brought about by non-classical light, examining the basic principles of parameter estimation and reviewing the state of the art.
