Single trusted qubit is necessary and sufficient for quantum realisation of extremal no-signaling correlations

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 these scenarios, the role of states is played by the so-called no-signaling boxes or no-signaling assemblages respectively....
