• Abstract: We report a combined experimental and theoretical study on the influence of microwave pulse durations on enantiomer-specific state transfer. Two triads of rotational states within a chiral molecule (1-indanol) are selected to address the possible scenarios. In the triad connected to the absolute ground state, the simplest triad that exists for all chiral molecules, the enantiomer-specific state transfer process simplifies into a sequence of two-level transitions. The second triad, including higher rotational states, represents a more generic scenario that involves multiple Rabi frequencies for each transition. Our study reveals that the conventional $\frac{\pi}{2}-\pi-\frac{\pi}{2}$ pulse sequence is not the optimal choice, except for the ideal case when in the simplest triad only the lowest level is initially populated. We find that employing a shorter duration for the first and last pulse of the sequence leads to significantly higher state-specific enantiomeric enrichment, albeit at the expense of overall population in the target state. Our experimental results are in very good agreement with theory, substantiating the quantitative understanding of enantiomer-specific state transfer.

  Transfer of population between two intersecting quantum states is the most fundamental dynamical event. We show that coupling to additional states, present in all real-world systems, can cause a measurable delay in population transfer. Results have implications for many research areas, such as atomic and molecular physics, charge transfer or light harvesting.

  We derive a pulse-area theorem for a cyclic three-level system driven by three linearly polarized microwave pulses. We show that two enantiomers with opposite handedness can be transferred to different target states by designing three microwave pulses. This work contributes an alternative pulse-area theorem to the field of quantum control, which has the potential to determine the chirality of enantiomers in a mixture.
