Figure 1 Recently, active phase manipulation of ultrashort laser pulses has permitted researchers to direct the outcome of photoinduced molecular dissociations by exploiting quantum-mechanical interferences. Martín et al. (p. 629; see the Perspective by Sanov) show that even simple excitation of the H2 molecule with high-energy, linearly polarized light can induce asymmetry in the trajectories followed by the formation of emergent proton, electron, and H atom products. Using high-level quantum mechanical calculations and precise experimental imaging techniques, the authors show that entanglement of two dissociation pathways of opposite parity leads to correlations in the directions followed by the three fragments.
