Abstract
We introduce a novel quantum phenomenon combining entanglement and many-body interference, enabling the observation of N-particle interference while suppressing lower-order interferences. A four-photon experiment demonstrates high-visibility (nonlocal) interference patterns based on a collective four-particle phase.
