May 12, 2023 at 10:25 | comment | added | Fabio | Thank you, the answer is simpler then what I thught then. Is this true even in the case of multipartite entanglement? So a entanglement preserving channel/operator can be always written as a convex combination of local unitaries (possibly random). | |
May 12, 2023 at 10:20 | comment | added | Carlo Beenakker | not with local unitary operations; these just amount to a change of basis, any meaningful measure of entanglement should be basis independent. | |
May 12, 2023 at 10:20 | comment | added | Fabio | That's what I thought, but it seems not true. Meaning that given a separable state you cannot entangle it using local operations but given an entangled state you can destroy or decrease its entanglement with local operations. | |
