Fast experimental progress makes it possible to manipulate genuinely quantum states of larger and larger size. This project is concerned with fundamental and practical aspects of large quantum systems. We know from quantum metrology that large that the use of genuinely quantum states allows to achieve enhanced measurement precision as compared to any classical approach. In fact, the possible quantum advantage increases with the size of the quantum system, and triggers interest in studying and producing such large quantum systems. The possibility to manipulate larger states also triggers more fundamental questions: how to measure the size of a macroscopic quantum state, how does the quantum-to-classical transition occur, is there an explicit collapse mechanism and can we experimentally test it. All of this aspects will be studied during this project in some form.
