We will discuss the scientific program to be studied in a new gravitational spectrometer GRANIT in a broad context of quantum states (quantum behaviour) of ultracold neutrons (UCN) in gravitational \[1\] and centrifugal \[2\] potentials, as well as applications of these phenomena/spectrometer to various domains of physics, ranging from studies of fundamental short-range interactions and symmetries to neutron quantum optics and reflectometry using UCN. All these topics, as well as related instrumental and methodical developments have been discussed during dedicated GRANIT-2010 Workshop \[3\]. The GRANIT spectrometer has been recently installed at the Institut Laue-Langevin, Grenoble, France \[4\] and could become operational in near future. 1. V.V.
