Today, we are utilizing quantum physics to propel advancements in quantum information science and technology, yet there remain unanswered fundamental inquiries about the nature of quantum and its ability to exceed classical boundaries. Our strategy includes characterizing physical systems within phase space. In my presentation, I will examine the boundary between quantum and classical realms, introducing innovative, mathematically robust techniques for practical applications. These methods offer distinct insights into what differentiates the classical world from the quantum domain, and also facilitate the characterization of quantum states of light. For instance, we will confirm effects that surpass classical correlations using a theory that is friendly to experimental settings. We will showcase cutting-edge techniques for differentiating between classical and quantum phenomena that coexist in quantum optics experiments. This involves introducing concepts like nonclassicality quasiprobabilities and phase space inequalities, and investigating quantum effects in correlated systems, including hybrid systems.
Keywords: quantum states of light; optical test of quantum theory; quantum correlations; phase space methods; nonclassicality
