Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

Bell's theorem represents a significant advance in understanding the conceptual
foundations of quantum mechanics. The theorem shows that essentially all local theories of …

Correlations of linear polarizations of pairs of photons have been measured with time-
varying analyzers. The analyzer in each leg of the apparatus is an acousto-optical switch …

The linear-polarization correlation of pairs of photons emitted in a radiative cascade of
calcium has been measured. The new experimental scheme, using two-channel polarizers …

When we were preparing the first edition of this book, the concept of de coherence was
known only to a minority of physicists. In the meantime, a wealth of contributions has …

In this classic, David Bohm was the first to offer us his causal interpretation of the quantum
theory. Causality and Chance in Modern Physics continues to make possible further insight …

This important work provides an account of the philosophical foundations of quantum theory
that should become a classic text for scientists and nonscientists alike. Hughes offers the first …

Bell inequalities are intended to show that local realist theories cannot describe the world. A
local realist theory is one where physical properties are defined prior to and independent of …

A review is given of correlation experiments in optics which explicitly distinguish between
the predictions of classical and quantum theory. In particular, the Cauchy-Schwarz and Bell's …

It is a very emotional experience to contribute to this book commemorating of John Bell. I first
met John in 1975, a few months after reading his famous paper [1]. I had been so strongly …
