The duration, strength and structure of memory effects are crucial propertiesof physical evolution. Due to the invasive nature of quantum measurement, suchproperties must be defined with respect to the probing instruments employed.Here, using a photonic platform, we experimentally demonstrate this necessityvia two paradigmatic processes: future-history correlations in the firstprocess can be erased by an intermediate quantum measurement; for the secondprocess, a noisy classical measurement blocks the effect of history. We thenapply memory truncation techniques to recover an efficient description thatapproximates expectation values for multi-time observables. Ourproof-of-principle analysis paves the way for experiments concerning moregeneral non-Markovian quantum processes and highlights where standard opensystems techniques break down.
