@vili-1 I believe I resolved these (afaik) with [Jake's deterministic derivation for eigenvalues and eigenvectors](https://github.com/jakelishman/qiskit-terra/tree/storage/deterministic-weyl-decomposition). You can try that and see if that resolves the issue. Overall, this module as...

I was trying the `M` value from the paper for magic basis, and NOW I know why Jake used the unnormalized version HEHEHE. These floating point errors are killing me.

Greetings there all. Just dropping by to ask if there have been any progress on this, or a way to mitigate the floating point error I mentioned.

I see. So, there's no way to at least mitigate them a bit? Because in the minimally reproducible example I sent above, you can see the issue (and it's just...

Issue is that with Windows and Mac Os, the decomposition is wrong (as in the circuit they construct are not what you encode). That's what I mean by mitigating. I...

I'll paste it here ASAP. IIRC my unit test is an example of this: ```py def test_decomp1(self) -> None: """ Test `TwoQubitDecomposition._decomp1()`. """ # Initialize a circuit circuit = QiskitCircuit(2)...

IIRC the example I sent earlier with `U` is actually about this one, which shows that Ubuntu gets the correct one, whereas Windows gets this wrong one in ACTUAL. The...

Wondering if this is needed ```py if mux_simplify: circuit.append(diagonal, [q_target] + q_controls) else: circuit.append(diagonal, q) ``` Isn't `q` also `[q_target] + q_controls`? If we ignore `mux_simplify`, then `q_target=q[0]`, and `q_controls=q[1:]`,...

May I ask when this will be merged with main?

@alexanderivrii Multiplexors are essentially uniformly controlled gates. The main use of them for me has been in the implementation of state and unitary synthesis by Shende. If one can implement...
