Function controlledRotateX

Source 
pub unsafe extern "C" fn controlledRotateX(
    qureg: Qureg,
    controlQubit: c_int,
    targetQubit: c_int,
    angle: f64,
)
Expand description

Applies a controlled rotation by a given angle around the X-axis of the Bloch-sphere. The target qubit is rotated in states where the control qubit has value 1.
