Summary form only given. Contrarily to the classical physics picture, according to quantum mechanics the observable properties of the objects do not yield defined values, until a measurement is performed. The measurement outcome depends indeed also on the set of observables that is being measured [1]. Such a fundamental aspect of Nature is named quantum contextuality and it has been studied in several experimental systems, including single particles [2, 3]. Interestingly, it was recently suggested that even the non-classical power of quantum computing originates from contextuality [4]. Therefore, it is highly relevant to find experimental evidence of this aspect in technological platforms that may be adopted in future quantum computing devices, such as integrated photonics [5-7]. In this work we investigate experimentally quantum contextuality of a single photon on-a-chip, employing reconfigurable photonic circuits fabricated by femtosecond laser waveguide writing [7, 8].
