Quantum Energy Teleportation - UWSpace
... In some sense the entropy is a measure of uncertainty in a random variable. Here is a rough sketch of how this concept applies to certain situations: say we have an alphabet X and for any given message there is a probability p(x) that a given letter X is x. Then, if we consider how one could optimal ...

Superposition, Entanglement, and Raising Schrödinger’s Cat Nobel Lecture, December 8, 2012
... Schrödinger dubbed this an entangled state because the state of the particle is correlated with the state of the cat. That is, upon measurement, if the particle is observed to be undecayed, one can say with certainty that the cat is alive, and vice versa. But before measurement, the particle and cat ...

Bell's theorem
.svg?width=300)
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:
