Entanglement without nonlocality
Dominic Horsman, Vlatko Vedral
We consider the characterization of entanglement from the perspective of a Heisenberg formalism. We derive an original two-party generalized separability criteria, and from this de…
Macroscopic Entanglement and Phase Transitions
Janet Anders, Vlatko Vedral
This paper summarises the results of our research on macroscopic entanglement in spin systems and free Bosonic gases. We explain how entanglement can be observed using entanglement…
Developing the Deutsch-Hayden approach to quantum mechanics
Dominic Horsman, Vlatko Vedral
The formalism of Deutsch and Hayden is a useful tool for describing quantum mechanics explicitly as local and unitary, and therefore quantum information theory as concerning a "flo…
How to Extract Entanglement from a Piece of Solid or a Bunch of Neutrons
Marcelo O Terra Cunha, Vlatko Vedral
We review how to obtain spin entangled pairs of fermions from a Fermi gas. An experiment with neutrons is proposed in order to get such pairs.
Spatial Entanglement of a Free Bosonic Field
L. Heaney, J. Anders, V. Vedral
In this paper we discuss the entanglement properties of a thermal non-relativistic free bosonic field. We demonstrate how to formally construct spatial modes in order to use a cont…
Local extraction of EPR entanglement from classical systems
D. Kaszlikowski, V. Vedral
Coherent states with large amplitudes are traditionally thought of as the best quantum mechanical approximation of classical behavior. Here we argue that, far from being classical,…
