We present a source of entangled photons that violates a Bell inequality free of the “fair-
sampling” assumption, by over 7 standard deviations. This violation is the first reported …

It is widely accepted that consciousness or, more generally, mental activity is in some way
correlated to the behavior of the material brain. Since quantum theory is the most …

In recent years, the use of information principles to understand quantum correlations has
been very successful. Unfortunately, all principles considered so far have a bipartite …

Consider a game where a refereed chooses (x, y) according to a publiclyknown distribution
PXY, sends x to Alice, and y to Bob. Withoutcommunicating with each other, Alice responds …

We describe a new technique for obtaining Tsirelson bounds, which are upper bounds on
the quantum value of a Bell inequality. Since quantum correlations do not allow signalling …

We investigate the concept of entropy in probabilistic theories more general than quantum
mechanics, with particular reference to the notion of information causality (IC) recently …

Abstract Information plays an important role in our understanding of the physical world.
Hence we propose an entropic measure of information for any physical theory that admits …

Recent work in quantum information science has produced a revolution in our
understanding of quantum entanglement. Scientists now view entanglement as a physical …

In this chapter, a general mathematical framework for probabilistic theories of operationally
understood circuits is laid out. Circuits consist of operations and wires. An operation is one …

The reconstruction of quantum physics has been connected with the interpretation of the
quantum formalism, and has continued to be so with the recent deeper consideration of the …
