Information backflow may not indicate quantum memory
Michal Banacki, Marcin Marciniak, Karol Horodecki +1
We analyze recent approaches to quantum Markovianity and how they relate to the proper definition of quantum memory. We point out that the well-known criterion of information backf…
On the edge of the set of no-signaling assemblages
Michał Banacki, Ricard Ravell Rodríguez, Paweł Horodecki
Following recent advancements, we consider a scenario of multipartite postquantum steering and general no-signaling assemblages. We introduce the notion of the edge of the set of n…
Single trusted qubit is necessary and sufficient for quantum realisation of extremal no-signaling correlations
Ravishankar Ramanathan, Michał Banacki, Ricard Ravell Rodríguez +1
Quantum statistics can be considered from the perspective of postquantum no-signaling theories in which either none or only a certain number of quantum systems are trusted. In thes…
