Scalable multiparticle entanglement of trapped ions

Article Abstract:

The features of entanglement are particularly evident if the particles can be individually controlled and physically separated but both the experimental realization and characterizations of entanglement become very difficult for systems with many particles. A detailed analysis conforms that the entanglement is genuine and the availability of multiparticle entangled states with information in the form of density matrices create a test bed for theoretical studies of multiparticular entanglement.

Many lives in many worlds

Article Abstract:

The PhD thesis by Hugh Everett, 'The Many-Worlds Interpretation of Quantum Mechanics' which specifies the state of the Universe in terms of a mathematical object called a wave function, stating that atoms could be in two places at once is reviewed.

Entanglement hits the big time

Article Abstract:

The phenomenon of entanglement is discussed. Entanglement describes a correlation between quantum mechanical systems, such as photons or atoms, that does not occur in classical, Newtonian physics.
