摘要：
The notion of the entanglement of a quantum evolution was discussed by simply observing the notions developed for quantum state entanglement. The notion of entanglement was extended from quantum states to the level of general quantum evolutions. This was achieved by considering multipartite unitary transformations as a element of Hilbert space and then extended to general quantum operations. The relation between entanglement of unitary U and entangling power was also established.
