Abstract:
Characterizing the underlying processes contributing to a light field has wide ranging applications throughout physics. In particular, knowledge of the different modes and sources of a field is often vital for engineering sources of non-classical light in a way to minimize coupling to unwanted modes that can cause loss and decoherence of quantum information. The photon number statistics of an optical field can provide a wealth of information, but to date most work has been limited to one- and two-fold photodetection. I will discuss how higher order photon number statistics can be used to reconstruct the underlying modes of optical fields and present an experimental demonstration of such a method. I will discuss how this method can be used for applications including mode-matching biphoton collection, producing factorizable states of photon pairs, minimizing classical background emission from single-emitter sources, and characterizing the number and degree of squeezing in multimode continuous variable entangled states.
