I think that paper is saying that you have to use N independent 2D numbers, not 2N independent 1D numbers. Complex numbers are literally the same as 2D real nu

Complex numbers are literally the same as 2D real numbers with the rotational symmetry constraint. https://www.reddit.com/r/Physics/comments/11ujjjd/quantum_theory_based_on_real_numbers_can_be/ https://www.reddit.com/r/Physics/comments/11ujjjd/quantum_th...
