 *Local Disentanglement in Relativistic Quantum Field Theory*

* *

ABSTRACT


In their paper on "Entanglement and Open Systems in Algebraic Quantum Field
Theory", Clifton and Halvorson (2001) raised the question whether
entanglement between quantum systems can be destroyed by means of local
operations and claimed that, contrary to non-relativistic quantum
mechanics, this can never be the case in relativistic quantum field theory.
In this talk I will argue that Clifton and Halvorson's no-go result applies
only to a special kind of local operations, and thereby I will reject their
conclusion. In fact, after providing sufficient conditions for local
disentanglement to be achieved, I will show that, if the split property
holds, there exists a class of local operations which disentangle all
states across any pair of spacelike separated quantum field systems.
