Throughout the last decade quantum interferometry with complex matter has grown from a Gedankenexperiment to a well developed field of research. Here we discuss the merits and draw-backs of far-field diffraction at material [1] and optical [2] gratings as well as a near-field interferometer that allows to increase both the detected flux as well as the mass limits in de Broglie interferometry [3,4]. A most promising instrument, at present, is an all-optical Talbot-Lau interferometer. It promises to shift matter wave interferometry to masses even beyond the limit of a million atomic mass units [5]. We discuss how such an interferometer can become important for exploring fundamental decoherence and dephasing phenomena and how it can become useful as a tool for measuring the electromagnetic or structural properties of nanoparticles [6].
