Quantifying Entanglement
... The central problem we explore in this essay is the quantification of entanglement. For starters (chapter 1), we give some historical background and explain exactly what entanglement is. Next (chapter 2), we move to the main question, namely, how one goes about prescribing and then calculating measu ...

On Quantum vs. Classical Communication Complexity
... All communication models that we have seen can be “augmented” by allowing Alice and Bob (but not the referee) to use shared randomness, or even shared entanglement. Shared randomness matters only in the SMP regime, as O(log n) shared random bits are always sufficient. We do not have, as of today, an ...

A quantum coordinated version of rock-paper-scissors, for example, where two players coordinate against a third produces a payoff asymptotic to 1/3 rather than 1/9. Moreover, this effect is not achievable through any ...

Bell's theorem

Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
