Quantum information and $CP$ measurement in $H\ensuremath{\rightarrow}{\ensuremath{\tau}}^{+}{\ensuremath{\tau}}^{\ensuremath{-}}$ at future lepton colliders

Abstract We introduce a methodology and investigate the feasibility of measuring quantum properties of tau lepton pairs in the H→τ+τ− decay at future lepton colliders. In particular, observation of entanglement, steerability, and violation of Bell inequalities are examined for the International Linear Collider (ILC) and Future Circular e+e− Collider (FCC-ee).
