Scientists have experimentally observed collective quantum tunneling in a system of ultracold atoms, a phenomenon predicted theoretically but challenging to verify. This study reveals how a group of atoms can synchronously pass through an energy barrier, behaving as a single quantum entity. The finding is crucial for understanding quantum coherence in many-body systems and opens new avenues for the development of quantum technologies.
