qBOUNCE studies gravitationally bound quantum states of ultracold neutrons (UCN) using gravity resonance spectroscopy ( GRS ). This technique offers a new way of looking at gravitation at short distances based on quantum interference [1,2]. In the past years, the qBOUNCE collaboration successfully commissioned a new Ramsey-type GRS experiment at the Institute Laue-Langevin (Grenoble), which increases the achievable sensitivity by more than an order of magnitude with respect to previous implementations [3]. In 2018 we measured the first gravitational state transitions with the new setup [7]. This Ramsey-type implementation is not only sensitive to a range of hypothetical variations of Newton's potential at the micro-scale [5,6], but also enables to test the electric charge neutrality of the neutron [4]. We present the results of the first neutron charge measurement and give an outlook on future developments.
