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

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

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

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

Certifying beyond quantumness of locally quantum no-signaling theories through a quantum-input Bell test

Physical theories constrained with local quantum structure and satisfying the no-signalling principle can allow beyond-quantum global states. In a standard Bell experiment, correlations obtained from

One-Shot Yield-Cost Relations in General Quantum Resource Theories

A quantitative relation is established between the one-shot distillable resource yield and dilution cost in terms of transformation errors involved in these processes and is applicable to quantum state and channel manipulation with respect to any type of quantum resource and any class of free transformations thereof.

Local Quantum Measurement Demands Type-Sensitive Information Principles for Global Correlations

Physical theories with local structure similar to quantum theory can allow beyond-quantum global states that are in agreement with unentangled Gleason’s theorem. In a standard Bell experiment any

Estimating Coherence Measures with Untrusted Devices

The superposition of quantum states, quantified by coherence, is a fundamental feature to distinguish quantum mechanics from classical theories. Estimations of coherence with perfectly characterised

Secure quantum key distribution with realistic devices

This review gives both sides of the story, with the current best theory of quantum security, and an extensive survey of what makes quantum cryptosystem safe in practice.

The type-independent resource theory of local operations and shared randomness

This work introduces a unifying framework which subsumes the full range of nonsignaling resources, as well as the games and experiments which probe them, into a common resource theory: that of local operations and shared randomness (LOSR).

Bipartite Postquantum Steering in Generalized Scenarios.

It is shown that by relaxing this traditional setup, bipartite steering incompatible with quantum theory is possible, and a method to bound quantum violations of steering inequalities in these scenarios is presented.
