Enantiomer Superpositions from Matter-Wave Interference of Chiral Molecules

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 two enantiomers by far-field diffraction and resulting tunnelling dynamics observed. We determine impact ro-vibrational phase averaging propose setup sensing enantiomer-dependent forces, parity-violating weak interactions, environment-induced superselection handedness, as suggested to resolve Hund's paradox.
