  • Quantum-network protocols based on photon-atom interfaces have stimulated a great demand for single-photon sources with narrow bandwidth. Here the authors report the generation of entangled photon pairs with controllable bandwidth and coherence time from a Doppler-broadened hot atomic vapour cell.

  • Observing spin-changing atom–molecule collisions with quantum-state precision provides clues of short-range interactions. Now it is shown that the outcomes of the KRb + Rb collision only align with a statistical model after assuming the non-conservation of mechanical angular momentum. The observations also contradict coupled-channel calculations that neglect vibrations and conical intersections.

  • Energy scrambling in intermediate complexes—which form in many chemical reactions—presents a major challenge to state-to-state control. However, nuclear spin tends to remain unchanged throughout reactions and now, by manipulating the reactants’ nuclear spins using an external magnetic field, control over the product state distribution of a bimolecular reaction has been demonstrated.
