RuntimeError: Can only build replacement circuits for basic gates: QControlBox

[ACE07-Sev]

Greetings there,

Hope you are well. I am trying to add tket2 to my library, and noticed that it doesn't support QControlBox. May I know when this would be added?

[ACE07-Sev]

For the moment, I found that by setting rebase=False resolves the issue.

Hello, could you say a bit more about how you were using tket2, which function were you calling?

Greetings there,

Hope you are well. Gosh, I'm really embarrassed, I actually forgot to add the reproduction code. Really sorry about that. I believe I was running this:

from pytket import Circuit, OpType
from pytket.circuit import Op, QControlBox
from tket2.circuit import Tk2Circuit, render_circuit_mermaid
from tket2.passes import badger_pass


setattr(
    Tk2Circuit,
    "_repr_markdown_",
    lambda self: f"```mermaid\n{render_circuit_mermaid(self)}\n```"
)

c = Circuit(3)
CX = QControlBox(Op.create(OpType.X), 1)
c.add_qcontrolbox(CX, [0, 1])

badger_pass(rebase=False).apply(c)

But now I'm getting a new error (which I wasn't getting before):
