The validity of the superposition principle and of Born’s rule are well-accepted tenants of quantum mechanics. Surprisingly, it has been predicted that the intensity pattern formed in a three-slit ...

The quantum superposition principle has been tested on a scale as never before in a new study by scientists at the University of Vienna in collaboration with the University of Basel. Hot, complex ...

At the quantum boundary This experiment at the University of Vienna proves that objects as big as molecules can interfere. (Image: Robin Riegler) Ever since quantum theory was developed during the ...
