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