Workshop on Entanglement

Workshop on Entanglement

28-29 November 2014
University Paris-Diderot, laboratory SPHERE (CNRS, UMR 7219)
Room Luc Valentin, 454A (Building Condorcet)


Initially, the concept of entanglement has been coined by Schrödinger to
describe a fundamental property of a composed, physical system whose
parts have interacted in their common past (Schrödinger, 1935) :
"When two systems, of which we know the states by their respective
representatives, enter into temporary physical interaction due to known
forces between them, and when after a time of mutual influence the
systems separate again, then they can no longer be described in the same
way as before, viz. by endowing each of them with a representative of
its own. I would not call that one but rather the characteristic trait
of quantum mechanics, the one that enforces its entire departure from
classical lines of thought. By the interaction the two representatives
[the quantum states] have become entangled."
Entanglement is the central concept of quantum mechanics, which can
explain non-locality phenomena, as in all EPR-like experiments.
Entanglement can even be used as a physical resource in information
protocols, like quantum cryptography or quantum teleportation.
Moreover, as recently suggested by some researchers, the concept of
entanglement can be represented within the framework of a generalized,
possibly weakened, version of quantum theory where all a priori
references to the physical world have been relaxed -which thus gives
rise to applications beyond the strict material domain.
This workshop aims to deal with the concept of entanglement according to
its different aspects and its possible interpretations. Historical,
physical, metaphysical, informational and generalized approaches to this
very fruitful concept will be addressed.
