Whenever a physical quantity becomes essential to the realization of useful tasks, it is desirable to deﬁne proper measures or monotones to quantify it. In quantum mechanics, coherence, entanglement, and Bell nonlocality are examples of such quantities. Given a quantum state (cid:37) and a quantiﬁer E ( (cid:37) ), both arbitrary, it is a hard task to determine E ( (cid:37) ⊗ N ). However, if the ﬁgure of merit E turns out to be additive, we simply have E ( (cid:37) ⊗ N ) = Ne , with e = E…

The results show that the most basic question of classical capacity of a quantum channel remains open, with further work needed to determine in which other situations entanglement can boost capacity.

### “Squashed entanglement”: An additive entanglement measure

- Computer Science, Mathematics
- 2004

A new entanglement monotone for bipartite quantum states is presented, inspired by the so-called intrinsic information of classical cryptography and is given by the halved minimum quantum conditional mutual information over all tripartite state extensions: it is convex, additive on tensor products, and superadditive in general.

This work finds approximate and exact characterizations of this trade-off for various channels of interest, including dephasing, depolarizing and erasure channels, and develops several bounds that are valid for general quantum channels and can be computed for small instances.

New entanglement monotones are introduced which generalize, to the case of many parties, those which give rise to the majorization-based partial ordering of bipartite states' entanglements, and polynomial invariants under local unitary transformations are investigated.

This work studies measures that can be described by E(ρ⊗N ) = E(e;N) 6= Ne, that is, measures for which the amount of resources of N copies is still determined by the single real variable e, but in a nonlinear way.
