  text: The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
    space, is ideally suited for quantum control. Molecular angular momentum is naturally
    quantized, time evolution is governed by a well-known Hamiltonian with only a
    few accurately known parameters, and transitions between rotational levels can
    be driven by external fields from various parts of the electromagnetic spectrum.
    Control over the rotational motion can be exerted in one-, two-, and many-body
    scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity
    of bimolecular reactions, or encode quantum information to name just a few examples.
    The corresponding approaches to quantum control are pursued within separate, and
    typically disjoint, subfields of physics, including ultrafast science, cold collisions,
    ultracold gases, quantum information science, and condensed-matter physics. It
    is the purpose of this review to present the various control phenomena, which
    all rely on the same underlying physics, within a unified framework. To this end,
    recall the Hamiltonian for free rotations, assuming the rigid rotor approximation
    to be valid, and summarize the different ways for a rotor to interact with external
    electromagnetic fields. These interactions can be exploited for control—from achieving
    alignment, orientation, or laser cooling in a one-body framework, steering bimolecular
    collisions, or realizing a quantum computer or quantum simulator in the many-body
    setting.
