Creating and sharing knowledge for telecommunications

Seminar - Recent research activities in EGOKITUZ

on 03-09-2015

... Egokutiz is a Laboratory of Human-Computer Interaction, in Spain, for Special Needs that has participated in several R&D projects at national and international level. Julio Abascal, a Professor of Computer Architecture and Technology Department of the University of the Basque Country and co-founder of this laboratory, is coming to deliver a talk on the latest researches being developed there. Surely not to be missed, from the voice of the one who has developed human-robot interfaces for smart wheelchairs in the Assistive Mobile Robotics field.
Date & hour: 3 Sep. 2015 – 14.00h to 15.00h

We investigate the properties of entanglement between two modes of a free Dirac and Scaler Field as seen by two relatively accelerated parties. A uniformly accelerated observer is unable to access information about the whole of spacetime, therefore there is a loss of information and a corresponding degradation of entanglement. The entanglement degradation in the limit of infinite acceleration for the Dirac field asymptotically reaches a non-vanishing minimum value. While for the case of bososnic field, a bipartite system becomes fully seperable in the limit of infinite acceleration. This means that the state always remains entangled to a degree for fermionic field and can be used in quantum information tasks, such as teleportation, between parties in relative uniform acceleration. We also investigate the effect of relativity on a tripartite maximally entangled GHZ state
