[draft] Split each tape into a different jaxpr during trace_quantum_function

### Before submitting TODO: changelog, tests, writeup of implementation Please complete the following checklist when submitting a PR: - [ ] All new functions and code must be clearly commented...

Currently only measurements are seeded for lightning simulators #936. It would be nice to have samples (aka shots) seeded too.

Provide access to different intermediate stages of mlir pipeline within the program

4

Currently, to access the intermediate stages of the milr compilation pipeline, we need to do `@qjit(keep_intermediate=True)`, and access the produced files with either python's `open()`, or some sort of `subprocess.call("less/cat...

`make format` and CI format checker should leave an empty line at the end of all source files (both python and cpp), but it currently does not

Added an empty pass boilerplate as a tutorial

6

**Context:** Added a tutorial for writing an empty pass boilerplate in the `catalyst` dialect that prints out hello world. The boilerplate code is on branch `docs/new-pass-tutorial` in commit https://github.com/PennyLaneAI/catalyst/commit/a857655b2f7afef6de19cdc1faaa226243e0bb58 **Benefits:**...

`jax.grad` (and `catalyst.grad`) sometimes randomly fails on a qjit-ted function containing a qnode: ```python dev = qml.device("lightning.qubit", wires=1) @qjit def cost(x): @qml.qnode(dev) def circuit(x): qml.PauliX(wires=0) #qml.RZ(0, wires=0) return qml.probs() return...

Find a better way to link blas routines from jaxlib

2

Currently catalyst links to the blas library shipped with scipy, not jaxlib, because jaxlib does not ship their blas library with a .so shared object file. This results in when...

Create a finite state machine analysis pass to propagate Pauli basis states, and use it to disentangle CNOTs

2

**Context:** In circuits that mostly involve the six Pauli eigenstates, the effect of gates can be described by a simple six-state finite state machine. This allows us to deduce their...

Add `static_argnames` option to qjit

4

**Context:** Adding a `static_argnames` option to qjit for users to configure static arguments by name. **Description of the Change:** Under the hood, this just maps the `static_argnames` to their argument...
