You can do QM without complex numbers as people are used to use them.
But it gets really awkward really fast.
- diedyesterday 3y agoAnd even then it's only a disguise. The two degrees-of-freedom which a complex numbers has, are still there (and QM needs it for interference, etc.). There is not way getting around the number of degrees-of-freedom of a system or a theory. It's as "real" as it gets.
