Correlations in the dynamics of quantum mechanical systems are involved in many phenomena, like sub - and superradiance.Furthermore, correlations between errors also play an important role in quantum error correction schemes. A measure to quantify these correlations was introduced in [1]. To increase the applicability of this measure to intermediately and large sized quantum systems, more efficient methods to estimate spatial correlations in quantum dynamics are presented. An experimental realisation of the protocols in an trapped ion quantum information processor will be presented.
