Quantum theory describes multipartite objects of various types: quantum states, nonlocal boxes, steering assemblages, teleportages, distributed measurements, channels, and so on. Such objects describe, for example, the resources shared in quantum networks. Not all such objects are useful, however. In the context of spacelike separated parties, devices which can be simulated using local operations and shared randomness are useless, and it is of paramount importance to be able to practically…

### Unifying different notions of quantum incompatibility into a strict hierarchy of resource theories of communication

- Computer Science
- 2022

This work unifies notions of POVMs, channels, and instruments incompatibility into one hierarchy of resource theories of communication between separated parties, and is able to pinpoint exactly what each notion of incompatibility consists of, in terms of information-theoretic resources.

### The resource theory of nonclassicality of channel assemblages

- Computer Science
- 2022

This paper provides a uniﬁed framework for studying the nonclassicality of various such generalizations of the EPR scenario using a resource theory wherein the free operations are local operations and shared randomness (LOSR).

### Multipartite channel assemblages

- Physics
- 2022

Motivated by the recent studies on post-quantum steering, we generalize the notion of bipartite channel steering by introducing the concept of multipartite no-signaling channel assemblages. We ﬁrst…
