*Created by: amccaskey* ```cpp def inverse_qft(int:nc) qubit[nc]:qq { for i in [0:nc/2] { swap qq[i], qq[nc-i-1]; } for i in [0:nc-1] { h qq[i]; int j = i + 1; int y = i; while (y >= 0) { double theta = -pi / (2^(j-y)); cphase(theta) qq[j], qq[y]; y -= 1; } } h qq[nc-1]; } ``` fails to compile due to the constant 2 being created as i64, while the variable nc is i32. Just need to add ZeroExtendIOp in the right place.
