Most of the techniques used today to measure external fields or forces employ concepts based on the principles of classical mechanics. In particular, Newton's second law is used, according to which the forces to be measured can be observed as a direct change in momentum. However, such classical schemes do not always provide the most accurate determination of force. The wave nature of matter and spectrum quantization, as fundamental principles of quantum mechanics, offer a way to develop precise force sensors, known as quantum generation, with many potential applications. These include navigation, Earth observation, electro-magnetometry, and research in materials science. I will review novel concepts of compact and robust force quantum sensors based on the interference of matter waves and spectrum quantization.
