A key prerequisite for these applications is the ability to completely control the rotational dynamics. The inherent degeneracy of quantum rotors poses a challenge for quantum control since selecting a particular rotational state cannot be achieved by spectral selection alone. Here, we prove complete controllability for rotational states of an asymmetric top belonging to degenerate values of the orientational quantum number M. Based on this insight, we construct a pulse sequence that energetically separates population in degenerate M-states. Introducing the concept of enantio-selective controllability, we determine the conditions for complete enantiomer-specific population transfer in chiral molecules and construct pulse sequences for the example of propanediol and carvone molecules for population initially distributed over degenerate M-states. Our work shows how to leverage controllability analysis for the solution of practical quantum control problems.","16 Seiten","https://refubium.fu-berlin.de/handle/fub188/34976||http://dx.doi.org/10.17169/refubium-34693","eng","https://creativecommons.org/licenses/by/4.0/","500 Naturwissenschaften und Mathematik::530 Physik::530 Physik","Applied mathematics||Atomic and molecular interactions with photons||Circular dichroism","Full quantum control of enantiomer-selective state transfer in chiral molecules despite degeneracy","Wissenschaftlicher Artikel","open access","110","10.1038/s42005-022-00883-6","Communications Physics","https://doi.org/10.1038/s42005-022-00883-6","5","2399-3650","Physik","Dahlem Center für komplexe Quantensysteme:::62c51c70-beb3-4ded-bdfd-90382588b080:::600","Springer Nature DEAL","Die Publikation wurde aus Open Access Publikationsgeldern der Freien Universität Berlin gefördert.","no"
