We consider an interferometer based on the concept of induced coherence,where two signal photons that originate in different second-order nonlinearcrystals can interfere. We derive a complementarity relationship that links thefirst-order coherence between the two interfering signal photons with aparameter that quantifies the distinguishing information regarding thenonlinear crystal where they originated. Astonishingly, the derivedrelationship goes beyond the single-photon regime and is valid for any photonflux rate generated. We show experimental results in the low photon-flux regimethat confirm the validity of the derived complementarity relationship.
