[BUG] parameterizing coefficients of `qml.dot` fails with qjit

2

Experienced `TracerBoolConversionError` when trying to parameterize coeffients of qml.dot with qjit. Minimal example code below. **Expected behavior:** (without qjit) ``` import pennylane as qml import jax.numpy as jnp from catalyst...

CRot cannot be differentiated with the adjoint method

2

Test circuit: ```py import numpy as np import pennylane as qml from catalyst import * @qml.qnode(qml.device(backend, wires=2), diff_method="adjoint") def f(x): qml.RY(0.321, wires=0) qml.CRot(x, 2 * x, 3 * x, wires=[0,...

Investigate `llvm::sys::getHostCPUName()` and `llvm::sys::getHostCPUFeatures()` to possibly improve code generation

1

We currently set these to "generic" and "" respectively. While we have the `targetMachine->setOptLevel(llvm::CodeGenOptLevel::None);` to avoid large compilation times, I believe that using the host cpu name and host cpu...

[WIP] Allow `catalyst.cond` to take in branch functions with arguments

7

**Context:** There is a restriction on `catalyst.cond`, that the conditional branch functions can never have arguments. This feature should be allowed, especially as we move towards FTQC. **Description of the...

Explicitly clarify that `AllocateQubits(N)` returns a vector from 0 to N in documentation

1

In [the documentation for adding a custom device](https://docs.pennylane.ai/projects/catalyst/en/stable/dev/custom_devices.html), it should be specified that the `AllocateQubits` method of a custom device should return a vector from 0 to `num_qubits`. Right now...
