Within the framework currently adopted for the description of the fundamental interactions, the particles involved in high-energy collisions are expected to exhibit a basic quantum behaviour. As a consequence of this statement, a novel class of "quantum" observables for collider studies naturally arises, whose physical interpretation is rooted in the characteristics of the underlying quantum states. We present a study on the sensitivity of quantum observables to new sources of CP-violation in top-antitop pairs ($t\bar{t}$), taking into account different production mechanisms. We also investigate how the same additional sources would affect the quantum tomography protocol adopted for the reconstruction of quantum states in collider environments. The ability to discriminate the stage where new physics would modify the current theoretical predictions is also discussed.
