Functions:

| Name                | Description                    |
| ------------------- | ------------------------------ |
| `select_rotation`   | \[Qmod core-library function]. |
| `select_z_rotation` | \[Qmod core-library function]. |

### select\_rotation

<pre><code>select\_rotation(
basis: Pauli,
angles: CArray\[CReal],
selector: Const\[QNum],
target: QBit
) -> None</code></pre>

\[Qmod core-library function]

Applies a set of controlled single-qubit rotations to a target qubit, using
a specified rotation axis and a list of rotation angles.

**Parameters:**

| Name       | Type            | Description                                                                           | Default    |
| ---------- | --------------- | ------------------------------------------------------------------------------------- | ---------- |
| `basis`    | `Pauli`         | The Pauli operator defining the rotation axis.                                        | *required* |
| `angles`   | `CArray[CReal]` | The list of rotation angles in radians. The list must have length 2\*\*selector.size. | *required* |
| `selector` | `Const[QNum]`   | The qubits that act as the selection register.                                        | *required* |
| `target`   | `QBit`          | The qubit on which the selected rotation is applied.                                  | *required* |

### select\_z\_rotation

<pre><code>select\_z\_rotation(
angles: CArray\[CReal],
selector: Const\[QNum],
target: Const\[QBit]
) -> None</code></pre>

\[Qmod core-library function]

Applies a set of controlled single-qubit Z rotations to a target qubit, using
a list of rotation angles.

**Parameters:**

| Name       | Type            | Description                                                                           | Default    |
