Abstract

In this contribution, we show that the use of conditional measurements in the resonant interaction of two quantized electromagnetic fields gives rise to nonclassical multiphoton processes. Furthermore, we demonstrate that this phenomenon may enable a robust integrated-optics protocol to engineer quantum states containing a high number of photons, thus making it a potentially appealing platform for exploring mesoscopic quantum phenomena.
