Projects

The underlying issues of this project are to address, theoretically and experimentally, the problems of discriminating among non-orthogonal states of high-dimensional quantum systems in the discrete (qudits) and continuous variables domain (single-photon images), covering both fundamental and applied aspects of the subjects., Universidad de Concepción, , 2012-03-01

Proyecto cuyo objetivo es optimizar los recursos de red y su gestión a través del desarrollo de un prototipo experimental de aprovisionamiento dinámico y monitoreo de redes virtuales independientes, sobre una red física común y extendida, que responda a las crecientes necesidades en temas avanzados de redes del sector productivo y de investigación., Universidad de Concepción, , 2011-12-01

Nowadays, distributed computing (DC) applications such as ubiquitous participatory sensing, wireless sensor networks (WSNs), and in-network DC are available everywhere due to the low cost of small-sized devices which have processing and wireless communication capabilities. These scenarios impose new constraints to DC, namely, a highly dynamic topology, a considerable number of computing elements (CEs), with restricted computing-power and limited amount of power for consumption. The success of this new class of applications is closely related to scalability issues and to the efficient use of both the limited energy resources and computing power of the CEs. To do so, control mechanisms must be provided to applications and CEs so that they can deal with the problem of smartly and transparently distributing and executing applications among the CEs. This research effort tackles the problem of efficiently allocating applications onto the available CEs of a distributed computing system (DCS). Here, the specific class of DC applications where hand-held devices and wireless sensors collect, process and disseminate spatial, temporal and/or environmental information, at different time scales, will be considered. The resource allocation problem regarded here aims to answer the questions of: How to efficiently map an application onto a finite number of CEs, while considering their energy consumption, their limited and heterogeneous computing power, the highly dynamic behavior of both the communication network as well as the CEs, and the scalability of the solutions to be provided. By answering this research question, control mechanisms may be provided to applications and CEs so that they can efficiently and transparently distribute and execute applications among the CEs., Universidad de Concepción, , 2011-10-01

This project aims to experimentally perform the violation of Bell´s inequalities while simultaneously closing the post-selection and locality loopholes, for which it is required to have spatially separated communicating parties. This experimental setup will also allow us to perform quantum cryptography with genuine energy-time entanglement., Universidad de Concepción, , 2011-10-01
