Anomalies of Wave-Particle Duality due to Translational-Internal Entanglement

Michal Kolar, Tomas Opatrny, Nir Bar-Gill, Gershon Kurizki

abstract: We predict that if internal and momentum states of an interfering object are correlated (entangled), then by measuring its internal state we may infer both path (corpuscular) and phase (wavelike) information with much higher precision than for objects lacking such entanglement. We thereby partly circumvent the standard complementarity constraints of which-path detection.
