Complete extension: the non-signaling analog of quantum purification
Marek Winczewski, Tamoghna Das, John H. Selby +5
Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulate…
How to make unforgeable money in generalised probabilistic theories
John H. Selby, Jamie Sikora
We discuss the possibility of creating money that is physically impossible to counterfeit. Of course, "physically impossible" is dependent on the theory that is a faithful descript…
Reconstructing quantum theory from diagrammatic postulates
John H. Selby, Carlo Maria Scandolo, Bob Coecke
We present a reconstruction of finite-dimensional quantum theory where all of the postulates are stated in diagrammatic terms, making them intuitive. Equivalently, they are stated…
