**Describe the bug**
When mid-circuit measurements are included in a quantum circuit, the `ir` function fails to recognize these measurements correctly. The function erroneously adds measurements t…

**Describe the bug**
After parsing a quantum circuit written in OpenQASM 3.0 using the BraketSimulator, the conditional instructions (specifically the `if` statement and the `x` gate) are not include…

Hi everyone,
I’m encountering an issue when trying to run a quantum circuit using ProjectQ. Specifically, I’m getting the following error:
`RuntimeError: Too many compiler engines added to the Mai…

### Expected behavior
(I develop the `pennylane-qrack` custom back end.) When we run the [ZNE tutorial](https://github.com/unitaryfund/qml/blob/zne-catalyst-tutorial/demonstrations/tutorial_zne_cat…

### What is happening?
`Clifford.to_circuit()` returns a `QuantumCircuit` with empty `qregs`. I don't know if this is an expected behaviour, but it has changed since qiskit 1.1.2.
### How can we r…

#### Issue description
I am benchmarking quantum circuits using Catalyst on a GPU. However, the speedup over CPU execution seems unexpectedly low.
* *Expected behavior:* Much higher speedup (ord…

### What should we add?
[1] proposed an efficient way to synthesize the following special pattern of two-body terms (`IZZ` and `ZZI`) and three-body term (`ZZZ`) (Fig. 2 [1]).
It can halve the number…
