The qBounce experiment offers a new way of looking at gravitation based on
quantum interference. An ultracold neutron is reflected in well-defined quantum
states in the gravity potential of the Earth by a mirror, which allows to apply
the concept of gravity resonance spectroscopy (GRS). This experiment with
neutrons gives access to all gravity parameters as the dependences on distance,
mass, curvature, energy-momentum as well as on torsion. Here, we concentrate on
torsion.Comment: Contributed to the 11th Patras Workshop on Axions, WIMPs and WISPs,
