In my opinion, researchers are not honest when they do explain quantum computers mathematically. I have never seen an explanation with a narrative:

- Here are matrices, this is how we multiply them and get a resulting vector.

- Here are special kinds of matrices SU(N) which leave |\Psi|^2 invariant, and here is an example for multiplying.

- Quantum computers are just SU(N) matrix multiplication accelerators.

At this point, no hype can survive and neither funding.
