Physicists from Heinrich Heine University Düsseldorf (HHU) and the German Aerospace Center (DLR) have demonstrated that quantum mechanics does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used, according to a study published in Physical Review Letters.
The American Physical Society has dedicated a “Highlight” to these findings in its Physics Magazine.
The Role of Imaginary Numbers in Quantum State Evolution
The collaboration between Heinrich Heine University Düsseldorf and the German Aerospace Center focused on examining a fundamental property of quantum mechanics. The team demonstrated that the theory does not necessarily need to be formulated with imaginary numbers. Real numbers can in fact also be used.
