Abstract

Quantum sensing exploits the possibility of manipulating single quantum objects and of measuring external physical quantities with unprecedented accuracy. It offers new functionalities that cannot be obtained with classical means. Quantum sensors can be based on atomic vapours, cold atoms, dopants in solid-state materials, etc. In the latter category, the nitrogen vacancy centre in diamond has received particular attention in recent years due to its very attractive characteristics.
