  • The Hong–Ou–Mandel effect is a well-known demonstration of quantum interference phenomena between pairs of indistinguishable bosons, yet it has only been seen with massless photons. Here, the authors propose an approach to realize this effect for matter waves using two colliding Bose–Einstein condensates.

  • Momentum-entangled atom pairs are used to demonstrate quantum non-locality, where changing one atom in an entangled pair instantly alters the state of the other atom. This result paves the way to study interactions between quantum states and gravity.

  • Quantum coherence has been extensively investigated in quantum optics, but less is known about its properties in massive particles. The higher-order many-body correlation functions have now been measured in an atom optics experiment, validating Wick’s theorem.

  • Entangled particles some distance apart can be used to show the strikingly nonlocal nature of quantum mechanics. Here the authors generate spatially separated pairs of helium atoms by colliding Bose-Einstein condensates and show that they are entangled by observing nonlocal correlations.
