It has been know that Quantum Mechanics allows a strong and bizarre correlation among particles,
called entanglement, that is not possible in any alternative theories that are local and real. In those local-real
theories, correlations among particles must satisfy Bell inequalities, while Quantum Mechanics can violate them.
The entanglement and Bell inequalities are therefore thought of the key to understand Quantum Mechanics
in a deeper level and play an important role in quantum information and computation theories.
Violation of Bell inequalities has been observed in low energy experiments but it has not been tested at
high-energy collider experiments with energy higher or around the weak scale.
In this talk I will propose a collider measurement of various quantum properties in H->tau,tau
at future lepton colliders and discuss its possible application to the CP measurements.
