Description
Final states with spin-correlations allow the measurement of quantum entanglement at collider energies. The $H\to\tau\tau$ process is an excellent probe for this, due to the scalar nature of the Higgs boson, and the direct access to the $\tau$-lepton helicity through the angular distributions of the $\tau$-lepton decay products. We will present the prospects of such a measurement a future $e^+e^-$ Higgs factory using Delphes simulation samples for the signal and the relevant background processes. The construction of observables sensitive to quantum entanglement of the $\tau$-$\tau$ system will be discussed together with the impact of reconstruction and event selection effects on the sensitivity.
