Paradoxical consequences of multipath coherence: Perfect interaction-free measurements

Abstract

Quantum coherence can be used to infer the presence of a detector without triggering it. Here we point out that according to quantum mechanics, such interaction-free measurements cannot be perfect, i.e., in a single-shot... [ view full abstract ]
