  The rotation of trapped molecules offers a promising platform for quantum
technologies and quantum information processing. In parallel, quantum error
correction codes that can protect quantum information encoded in rotational
states of a single molecule have been developed. These codes are currently an
abstract concept, as no implementation strategy is yet known. Here, we present
a step towards experimental implementation of these codes by introducing
architecture-agnostic check and correction operators. These operators can be
decomposed into elements of the quantum logic spectroscopy toolbox that is
available for molecular ions. We then describe and analyze a measurement-based
sequential as well as an autonomous implementation strategy in the presence of
thermal background radiation, a major noise source for rotation in polar
molecules. The presented strategies and methods might enable robust sensing or
even fault-tolerant quantum computing using the rotation of individual
molecules.
