Researchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organizations were realized as secure, quantum encrypted information was sent over an eight node, mesh network.
It appears to be a paradox: ultra-thin material that absorbs all incident light. Nonetheless, it does exist. Researchers have demonstrated that at a thickness of 4.5 nanometer niobiumnitride (NbN) is ultra-absorbent. They have recorded a light absorption of almost 100%, while the best light absorption to date was 50%. This research brings the ideal light detector a step closer.

Preparations are under way for the restart of the Large Hadron Collider (LHC) the world’s most powerful particle accelerator. One of the most important systems needed to support the experiments that will utilise this great machine is the global computing grid: the worldwide LHC Computing Grid (WLCG). After months of preparation and two intensive weeks of 24--7 operation the LHC experiments are celebrating the achievement of a new set of goals aimed at demonstrating full readiness for the LHC data taking run expected to start later this year. Whilst there have been several large-scale data-processing tests in recent years, this was the first production demonstration involving all of the key elements from data taking through to analysis. Records of all sorts were established: data taking throughput, data import and export rates between the various Grid sites, as well as huge numbers of analysis, simulation and reprocessing jobs " ATLAS alone running close to 1M analysis jobs and achieving 6GB/s, of “Grid traffic”, the equivalent of a DVD worth of data a second, sustained over long periods. This result is particularly timely as it coincides with the transition of Grids into long-term sustainable e-infrastructures, clearly of fundamental importance to projects of the lifetime of the LHC. With the restart of the LHC only months away, one can expect a large increase in the number of Grid users: from several hundred unique users today to several thousand when data taking and analysis commences. This can only happen through significant streamlining of operations and the simplification of end-users’ interaction with the Grid. STEP’09 included massive-scale testing of end-user analysis scenarios, including “community-support” infrastructures, whereby the community is trained and enabled to be largely self-supporting, backed by a core of Grid and application experts.
