Information theoretical perspective on the method of Entanglement Witnesses
Paulo J. Cavalcanti, Giovanni Scala, Antonio Mandarino +1
We frame entanglement detection as a problem of random variable inference to introduce a quantitative method to measure and understand whether entanglement witnesses lead to an eff…
Every non-signalling channel is common-cause realizable
Paulo J. Cavalcanti, John H. Selby, Ana Belén Sainz
In this work we show that the set of non-signalling resources of a locally-tomographic generalised probabilistic theory (GPT), such as quantum and classical theory, coincides with…
Simulating all multipartite non-signalling channels via quasiprobabilistic mixtures of local channels in generalised probabilistic theories
Paulo J. Cavalcanti, John H. Selby, Jamie Sikora +1
Non-signalling quantum channels -- relevant in, e.g., the study of Bell and Einstein-Podolsky-Rosen scenarios -- may be simulated via affine combinations of local operations in bip…
Post-quantum steering is a stronger-than-quantum resource for information processing
Paulo J. Cavalcanti, John H. Selby, Jamie Sikora +2
We present the first instance where post-quantum steering is a stronger-than-quantum resource for information processing -- remote state preparation. In addition, we show that the…
