Concentrating partial entanglement by local operations.

If two separated observers are supplied with entanglement, in the form of n pairs of particles in identical partly-entangled pure states, one member of each pair being given to each observer; they can, by local actions of each observer, concentrate this entanglement into a smaller number of maximally-entangled pairs of particles, for example EinsteinPodolsky-Rosen singlets, similarly shared bet...

A New Entanglement Measure Induced By the

Evaluation and Prediction of Evoked Emotions Induced by Image Manipulations

Various image editing tools make our pictures more attractive, and at the same time, evoke different emotional responses. With powerful and easy-to-use imaging applications, capturing, editing and then sharing pictures have become daily life for many. This paper investigates the influence of several image manipulations on evoked emotions for different types of images. To do so, various types of...

Concentrating Entanglement by Local Actions – Beyond Mean Values

entanglement, quantum theory, quantum information, quantum computation, foundations of quantum mechanics Previous investigations of entanglement manipulations have focused on the average properties of the outcomes and little is known about the actual probability distribution. Here we go beyond the average properties. We show that, for a pure entangled state shared between two separated persons ...
