Macroscopicity of mechanical quantum superposition states
Phys. Rev. Lett 110, 160403 (2013)


We propose an experimentally accessible, objective measure for the macroscopicity of superposition states in mechanical quantum systems. Based on the observable consequences of a minimal, macrorealist extension of quantum mechanics, it allows one to quantify the degree of macroscopicity achieved in different experiments.
