Abstract

Molecular matter-wave interferometry enables novel strategies for
manipulating the internal mechanical motion of complex molecules. Here,
we show how chiral molecules can be prepared in a quantum superposition
of two enantiomers by far-field matter-wave diffraction and how the
resulting tunneling dynamics can be observed. We determine the impact of
rovibrational phase averaging and propose a setup for sensing
enantiomer-dependent forces, parity-violating weak interactions, and
environment-induced superselection of handedness, as suggested to
resolve Hund’s paradox. Using ab initio tunneling calculations,
we identify [4]-helicene derivatives as promising candidates to
implement the proposal with state-of-the-art techniques. This work opens
the door for quantum sensing with chiral molecules.
