Backpropagate over `mat` function, the analytical approach.

@MikeInnes Roger told me that you are interested in "quantize" Zygote, and put it into your paper. [Variational quantum eigensolver](https://www.nature.com/articles/ncomms5213?origin=ppub) is one of the killer applications on quantum computers. The...

Alternatives for the backend

I downloaded this package and played around with it for a while, but I feel GLMakie might not be the best choice for the backend. It is slow to first...

* In primitive block benchmark, we should use `put` rather than `repeat`? * Do not use `rand` in this benchmark, please specify a deterministic position for benchmark.

Batched block

We have already got batched register for solving the sampling problem. Also, I find pretty useful to have batched blocks, especially in simulating `kernel` quantum algorithms in > Schuld, Maria,...
