Quantum Mechanics May Not Need Imaginary Numbers After All

Source Summary

Physicists have shown that imaginary numbers may not be fundamentally required in quantum mechanics. Physicists at Heinrich Heine University Düsseldorf (HHU), working with the German Aerospace Center (DLR), have revisited a basic feature of quantum mechanics. Their study shows that the theory can be expressed using real numbers rather than relying on imaginary numbers. Quantum [...]
