Researchers at Laboratoire de Physique de l’École Normale Supérieure, ENS, investigated a complementarity relation between predictability and quantum coherence, representing particle-like and wave-like behavior in wave–particle duality, in a multi-path setup. Predictability is defined by the Bures distance between a state and the maximally mixed state, depending only on observed basis statistics.
