 ploration of quantum entanglement at TeV-scale energies has sparked increa
 sing interest in precision studies of the spin structure of weak-boson pai
 rs in LHC processes. Achieving a reliable spin interpretation of experimen
 tal data requires an accurate determination of polarisation and spin-corre
 lation coefficients\, incorporating electroweak (EW) and strong higher-ord
 er corrections\, as well as parton-shower and hadronisation effects. While
  most existing phenomenological analyses are limited to tree-level simulat
 ions\, recent advances have enabled the inclusion of higher-order correcti
 ons in the evaluation of quantum-information observables for di-boson (two
 -qutrit) processes. We demonstrate that properly determining the spin-dens
 ity-matrix entries\, and thereby correctly interpreting observables sensit
 ive to quantum entanglement\, demands the inclusion of realistic effects s
 uch as radiative corrections\, clustering-algorithm dependence\, off-shell
  effects\, fiducial selections\, and event reconstruction. Furthermore\, w
 e investigate the origin of the unusually large EW radiative effects obser
 ved in the spin-density matrix of the Z-boson with leptonic decays\, and w
 e propose a quantum-tomography approach that is both general and robust un
 der higher-order corrections.</p>
