    The entangling power of a unitary operator on a general finite-dimensional quantum system with and without ancillas was analyzed. The relations between the entangling power based on the von Neumann entropy and the entangling power based on the linear entropy were also provided. The results show that the entangling power of a general controlled unitary operator acting on two equal-dimensional qudits is proportional to the corresponding operator entanglement if linear entropy is adopted as the quantity representing the degree of entanglement.
