A Step Forward Toward Quantum Computers

 Asociacion RUVID (10/18/11)

 Researchers at Universitat Politecnica de Valencia (UPV) and Universitat Miguel Hernandez d’Elx (UMH) have developed a model that describes the full operation in a quantum regime of integrated optical modulators, which makes it possible for quantum computers to reach speeds of about 100 gigabytes per second.  The modulators could be used in future logical systems and quantum computers by applying the properties presented in the study, says UPV’s Jose Capmany.  “The ability to integrate several of these components into an optical chip opens the door to designing more complex, less expensive circuits by taking advantage of the economies of scale provided by photonic integration,” Capmany says.  The UPV-UMH study is a step toward the development of quantum communication and quantum computers, which would be a revolution in the telecommunications field.  “Currently, one of the obstacles to their development is that the demonstrations that have been made were based on extremely bulky assemblies, which entailed conditions that can only be reproduced in controlled laboratory environments,” Capmany says.

An Ecosystem of Supercomputers to Take India to Next Level

 Financial Express (India) (10/17/11) Ajay Sukumaran

As part of the 12th Five Year Plan, which runs from 2012-2017, India’s ministry of science and technology is considering the development of an ecosystem of high-performance computers that would provide supercomputing access to at least 25 percent of the country’s scientific population.  The Indian Institute of Science’s N. Balakrishnan is leading a national effort to map India’s capability in supercomputing, including building a four-tier ecosystem of machines with greater involvement in the private sector.  The first tier will include about six supercomputers with between 3 and 6 petaflops of computing power each, followed by 12 to 20 supercomputers that run at 200 to 500 teraflops.  The third tier will include 20 to 50 systems with 10-teraflop speed, and the lowest rung will include 50 to 100 regional 1-teraflop supercomputers.  “On the software development side, both for programming on the multicore as well as for scientific software development, the private industries will play a significant role,” according to Balakrishnan.  He says that once the 12th plan is complete, India will look to develop an exaflop system.
