This is your regularly scheduled reminder that the author of these papers (https://arxiv.org/abs/2101.10873, https://arxiv.org/abs/2111.15128), which this article is based on know very well that complex numbers have real matrix representations. What they add which your comment discounts is the locality structure of quantum mechanics, i.e. what happens when you combine multiple quantum systems. Specifically if the state of one system lives in A, and the state of another system lives in B then the state of a combined system lives in the tensor product A ⊗ B. If you do the trick where you…
