How do physicists know that two particles are entangled? Since in
relativity there is no such thing as simultaneity, then it must be
that in each reference frame there exists a unique kind of
correlation. Is this the case?
Entanglement can occur spontaneously when two atoms interact. For
the initial interaction, the atoms have to be in close proximity.

Entanglement: The Greatest Mystery in Physics

There are two kinds of books about quantum
mechanics. There are those in which we learn
about abstract concepts such as Hilbert spaces,
state vectors and density matrixes, but where the
author never addresses - or only pays lip-service
to - the question of what quantum mechanics
actually means. This is the approach often taken in
textbooks. The other, quite opposite, approach
focuses on the interpretative question - drawing all
kinds of conclusions and analogies, talking about
telepathy and other mysteries, and perhaps even
claiming that quantum mechanics transcends
Western philosophy.
Neither approach is very helpful when one wants
to understand what quantum mechanics really
means in a deep philosophical sense. Amir Aczel's
new book on entanglement - falling as it does into
neither category - avoids such pitfalls.
Anton Zeilinger from the Institute of Experimental
Physics at the University of Vienna reviews the
book in the May issue of Physics World
