Description

One class of gravity experiments within the qBounce project focuses on the realization of a Quantum Bouncing Ball, i.e. a measurement of the time evolution of a neutron bouncing above a horizontal plane. We have measured, the spatial probability distribution of this Schrödinger wave packet for different observation times with a spatial resolution of about 1.8μm. We illustrate the role of interference weaving the quantum carpet of several quantum states. After a first quantum reflection, several snapshots show the fall of the wave packet.
