Spin-density matrix which are commonly used in quantum mechanics have found a new interest in the community of collider physics over the last few years, introducing concepts like entanglement (the genuine quantum phenomenon in which 2 quantum systems cannot be described independently even separated by large distances) that were rarely used in collider physics until recently, with the first measurements of entanglement at LHC in 2024

In this talk I will present the work I did to automatise the computation of such spin-density matrices for collider purposes in the MadGraph framework and will present a different set of applications: including entanglement studies and MadSpin.
