Experimental quantum imaging distillation with undetected light

Abstract

Imaging based on the induced coherence effect makes use of photon pairs to obtain information of an object without detecting the light that probes it. While one photon illuminates the object, only its partner is detected, so no measurement of coincidence events are needed.The sought-after object's information is revealed observing a certain interference pattern on the detected photon. Here we demonstrate experimentally that this imaging technique can be made resilient to noise. We introduce an imaging distillation approach based on the interferometric modulation of the signal of interest. We show that our scheme can generate

Intensity interferometry for holography with quantum and classical light

“…Several recent works have demonstrated that quantum-correlated light can overcome certain limitations in conventional holography. Töpfer et al (3) and Fuenzalida et al (4) used frequencycorrelated beams to illuminate the object with a different wavelength than the detected light. Similarly, Chrapkiewicz et al (5) showed that Hong-Ou-Mandel interference between two single photons enables holography without needing phase stability.…”
