Exploring Fano interferometers towards entanglement detection — •Jörg Evers and Fabian Lauble — Max-Planck-Institut für Kernphysik, Heidelberg

Interferometry is an indispensable tool across all the natural sciences. Recently, we have proposed and implemented a new type of interferometer based on phase-sensitive Fano resonances. These Fano resonances appear if photons have two indistinguishable pathways from source to detector: either via a spectrally broad continuum channel, or via a spectrally narrow resonant bound state scattering channel. We have shown that these two channels can form interferometer arms [1], and experimentally demonstrated two different implementations of Fano interferometers in x-ray quantum optics [1,2]. Here, we review these Fano interferometers, and discuss their capabilities in particular related to the detection of single-photon mode entanglement [3]. 0.1cm [1] K. P.
