Information theory encompasses the apparently inherent probabilistic nature of quantum mechanics, our statistical understanding of thermodynamical systems, and computer s

,“It from Bit” and the Quantum Probability Rule,et us all the way to the quantum probability rule because an extra constraint, known as noncontextuality, is required. I outline the prospects for a derivation of noncontextuality within this approach and argue that it requires a realist approach to physics, or “bit from it”. I then explain why this

It from Qubit,try to convince him of the amazing theoretical power of such paradigm. Contrarily to the common belief, the whole history of physics is indeed a winding road making the notion of “physical object”—the “It”—fade away. Such primary concept, on which the structure of contemporary theoretical physics is

Thus one cannot assume that an ‘element of reality’ prexists to the measurement and, it is even more intriguing that unperformed/counterfactual observables enter the game. This is called quantum contextuality. Simple finite projective geometries are a good way to picture the commutation relations

The Tao of It and Bit,at quantum property to observe. This gives the observer a . in deciding the past history of the universe. Wheeler extended this participatory role to the emergence of the physical laws (.). Since what we know about the universe comes in yes/no answers to our interrogations, this led him to the idea

Information-Based Physics and the Influence Network,eardrums are buffeted by relentless waves of air molecules. My entire sensorium is excited by all that surrounds me. These experiences are all I have ever known, and for this reason, they comprise my reality. This essay considers a simple model of observers that are influenced by the world around th

Relative Information at the Foundation of Physics,out referring to subjectivism or idealism. It can also represent a key missing element in the foundation of the naturalistic picture of the world, providing the conceptual tool for dealing with its apparent limitations. I comment on the relation between these ideas and Democritus.
