      abstract     = {Superpositions of handed molecular states give rise to
                      achiral eigenstates, delocalized across a double-well
                      potential via tunneling. In principle, a coherent
                      superposition of these stationary eigenstates could
                      dynamically relocalize the molecules into chiral states,
                      which has only been demonstrated theoretically. Here, we
                      present a microwave six-wave mixing pump-probe study to
                      create and probe coherent chiral tunneling dynamics in a
                      rotational state. Through a time-resolved scheme, we uncover
                      the periodic time evolution of the induced chiral wavepacket
                      under field-free conditions, using enantiomeric excess as
                      the observable. We also demonstrate precise phase control of
                      this coherence via phase modulation during pump excitation.
                      Our results offer foundational evidence for the
                      superposition principle in chiral tunneling systems, with
                      implications for advancing quantum control in these system.},
