[Quantum Seminar] Pedro Barrios | Quantum mechanics based on real numbers: A consistent description

Quantum mechanics based on real numbers: A consistent description Abstract. Complex numbers play a crucial role in quantum mechanics. However, their necessity remains debated: whether they are fundamental or merely convenient. Recently, it was claimed that quantum mechanics based on real numbers can be experimentally falsified in the sense that any real-number formulation of quantum mechanics either becomes inconsistent with multipartite experiments or violates certain postulates. In this article we show that a physically motivated postulate about composite quantum systems allows to construct quantum mechanics based on real numbers that reproduces predictions for all multipartite quantum experiments. Thus, we argue that real-valued quantum mechanics cannot be falsified, and therefore the use of complex numbers is a matter of convenience. arXiv. https://arxiv.org/abs/2503.17307 About. www.linkedin.com/in/pedro-barrios-hita-293613217 Host.
