Probing the quantum superposition
principle
Does the quantum superposition principle hold on mesoscopic or
even macroscopic scales? The tremendous success of quantum theory notwithstanding, this question remains unsettled to date. I will discuss experimental tests of the quantum superposition principle, such as matter wave
interferometry with large particles as well as their implications on theories predicting a breakdown of quantum mechanics at macroscopic scales. I will also
explain how the degree of macroscopicity reached in various superposition experiments can be assessed
and compared.
The wave nature of highly massive particles can be tested in a near-field
interferometer based on standing VUV-light beams
