'Complex numbers are not needed for quantum mechanics': Physicists develop quantum model that uses only 'real' numbers for first time ever
SMRTR summary
Physicists have built a working version of quantum mechanics using only "real" numbers, settling a century-long debate about whether complex numbers are fundamental to the theory. By replacing a standard mathematical rule with a new bookkeeping system, researchers showed complex numbers are just a convenient tool, not a requirement.
