Quantum mechanics in its modern formulation relies on several fundamental axioms. One of these axioms is that states of a system are represented by complex wavefunctions. Another, the Born rule, relates these wavefunction to measurable probabilities by stating that the probability density equates the squared magnitude of the wavefunction. Interestingly, both axioms can be tested against potential generalisations by one and the same experiment in a multi-path interferometer. In this talk, I will give an introduction into the field, present the state of the art and our latest results in this direction, which have been obtained with both, free space and integrated waveguide interferometers.
