When calculating the samples of an 8-qubit Clifford circuit with the `clifford` backend, I get the error:
```Python
IndexError: index 9 is out of bounds for axis 1 with size 9
```
I have confirm…

I am prompted to ask this question by an offhand comment @Roger-luo made in https://discourse.julialang.org/t/quantikz-jl-for-drawing-quantum-circuit-diagrams-with-julia/52200
I am working on a libra…

Some backends, especially external ones*, may already have definitions for the gate matrices.
For this reason, I avoided encoding the matrices until now, since they are not always required.
Howeve…

Say I build a circuit using the `power` and `control` modifier on gates.
```py
from qiskit.circuit.library import *

Currently only single qubit pauli gate in `chain` and `prod` supports merging pauli gates.
Composite blocks like `kron` and `PauliString` with pure Pauli gates can be merged by when inside `chain`/…

### Expected behavior
It is expected that no gates will be added by calling qml.pauli.string_to_pauli_word() in a circuit.
```
import pennylane as qml
dev = qml.device("default.qubit", wires=3…

### What should we add?
Would be useful to be able to initialize `PauliGate()` with a `Parameter`, which can later be bound to specify whether the `PauliGate` is `I`, `X`, `Z`, or `Y`. Multiqubit Pau…

Hi, @AthenaCaesura ! You mentioned that there is a graph state simulator that can be "extracted" from this codebase. The dense tableau simulator I mentioned is https://github.com/QuantumSavory/Quantum…

### Expected behavior
Execution without failure (i.e. the QFIM is returned)
### Actual behavior
`WireError: Did not find some of the wires on device with wires .`
