Abstract

Our research explores fundamental aspects of quantum optics and quantum information through the study of multi-path and multi-particle interference. Using photonic and matter-wave systems, we investigate the foundations and limits of quantum theory, including higher-order interference, wave-particle duality, and possible extensions beyond standard quantum mechanics. By combining theoretical and experimental approaches, we aim to deepen the understanding of quantum interference and its role in future quantum technologies.
