Multipath and Multiparticle Tests of Complex versus Hypercomplex Quantum Theory

Author(s): Ece İpek Saruhan, Joachim von Zanthier, and Marc-Oliver Pleinert The axioms of quantum mechanics provide limited information regarding the structure of the Hilbert space, such as the underlying number system. The latter is generally regarded as complex, but generalizations of complex numbers, so-called hypercomplex numbers, cannot be ruled out in theory. Therefor… [Phys. Rev.
