“…Matter-wave interference has been observed with a variety of objects, with electrons [57,58], neutrons [68,69,86], atoms [22], and with increasingly large molecules (see, e.g., [6,38,44]). In the case of matter waves with atoms, entangled states with a high number of atoms have been realized [50], and it is even possible to realize atom lasers [14,45].…”

Quantum physics challenges our understanding of the nature of physical reality and of space-time and suggests the necessity of radical revisions of their underlying concepts. Experimental tests of quantum phenomena involving massive macroscopic objects would provide novel insights into these fundamental questions. Making use of the unique environment provided by space, MAQRO aims at investigating this largely unexplored realm of macroscopic quantum physics. MAQRO has originally been proposed as a medium-sized fundamental-science space mission for the 2010 call of Cosmic Vision. MAQRO unites two experiments: DECIDE (DECoherence In Double-Slit Experiments) and CASE (Comparative Acceleration Sensing Experiment). The main scientific objective of MAQRO, which is addressed by the experiment DECIDE, is to test the predictions of quantum theory for quantum superpositions of macroscopic objects containing more than 10 8 atoms. Under these conditions, deviations due to various suggested alternative models to quantum theory would become visible. These models have been suggested to harmonize the paradoxical quantum phenomena both with the classical macroscopic world and with our notion of Minkowski space-time. second scientific objective of MAQRO, which is addressed by the experiment CASE, is to demonstrate the performance of a novel type of inertial sensor based on optically trapped microspheres. CASE is a technology demonstrator that shows how the modular design of DECIDE allows to easily incorporate it with other missions that have compatible requirements in terms of spacecraft and orbit. CASE can, at the same time, serve as a test bench for the weak equivalence principle, i.e., the universality of free fall with test-masses differing in their mass by 7 orders of magnitude.

“…The decisive experiment to verify that the diffracted beams are phase coherent would be a working electron interferometer, using a geometry such as the one proposed by Marton (27;28). The corresponding atom interferometer has already been built using free-standing gratings (29), and has been used for fundamental studies based on measurements of atom wave phase shifts.…”

“…It is a Mach-Zender-type interferometer consisting of beam splitters for electrons D1 and D2 implemented through thin crystalline lamellae [5] and mirrors for electrons, M 1 and M 2 , which can be for example intense laser beams [6]. This interferometer must be supplemented by a spectrometer, as in the case of the set-up in [4] for neutrons, to observe the Aharonov-Bohm effect in p when the solenoid S carries electrical current.…”
