Description
We introduce a methodology and investigate the feasibility of measuring quantum properties of tau lepton pairs in the $𝐻 \to \tau^+ \tau^−$ decay at future lepton colliders. In particular, observation of entanglement and violation of Bell inequalities are examined for the ILC and FCC-ee. As a by-product, we show that a novel model-independent test of CP violation can be performed and the CP-phase of $H \tau \tau$ interaction can be constrained with an accuracy comparable to dedicated analyses.
