Studying nonclassical states of light generated by conditional measurements using click detectors — •Ananga Mohan Datta1, Konrad Tschernig2, Armando Pérez-Leija2, and Kurt Busch1,31Humboldt-Universität zu Berlin, Institut für Physik, AG Theoretische Optik & Photonik, 12489 Berlin, Germany — 2CREOL, The College of Optics and Photonics, University of Central Florida, Florida 32816, USA — 3Max-Born-Institut, Max-Born-Str. 2A, 12489 Berlin, Germany

Conditional measurements are a promising way to generate nonclassical states of light [1-2]. Here we use the statistics produced by click detectors [3] to study the quantum states of light generated via conditional measurements on a detuned waveguide coupler. We investigate the states when one input port is excited by a coherent state while a single-photon Fock state is fed into the other port. We then analyze the projected states when several detectors click in one of the output ports. We present the results of the binomial QB parameter [4] of the projected state as a measure for the degree of nonclassicality induced by conditional click detection.
