Abstract
The notion of entanglement can be naturally extended from quantum states to the level of general quantum evolutions. This is achieved by considering multipartite unitary transformations as elements of a multipartite Hilbert space and then extended to general quantum operations. We show some connection between this entanglement and the entangling capabilities of the quantum evolution.
