Atom interferometry has become a formidable tool
for high-precision quantum metrology applications as well as investigations into
the fundamental interconnections between relativity and quantum mechanics. On the other hand, quantum systems in the form of atomic clocks are routinely employed in tests of special and general relativity. The combination of atom interferometry and atomic clocks in terms of quantum-clock interferometry [1, 2] is a promising candidate for the investigation of special and general relativistic effects with and on quantum objects. In our contribution we investigate the realization of a quantum twin paradox via matter wave clock interferometry. In particular, we discuss the theoretical framework, realization and specific measurement scheme which allows us to extract the special relativistic twin paradox contribution from the interferometer phase shift.
