Research ArticleOpen accessIn the abstractDesign and Analysis of Adders using Nanotechnology Based Quantum dot Cellular AutomataS. Karthigai Lakshmi, G. AthishaProblem statement: The area and complexity are the major issues in circuit design. Here, we propose different types of adder designs based on Quantum dot Cellular Automata (QCA) that reduces number of QCA cells and area compare to previous designs. The quantum dot cellular automata is a novel computing paradigm in nanotechnology that can implement digital circuits with faster speed, … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Quantum and Classical Key Scheme for Two Servers Password AuthenticationA. Krishnan, T.S. ThangavelProblem statement: Traditional user authentication system uses passwords for their secured accessibility in a central server, which is prone to attack by adversaries. The adversaries gain access to the contents of the user in attack prone servers. To overcome this problem, the multi-server systems were being proposed in which the user communicate in parallel with several or all of the … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 6,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Error Correction Intuitive Approach in Quantum Communications ProtocolsAris Skander, Merabtine Nadjim, Malek BenslamaQuantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeedup of Particle Transport Problems with a Beowulf ClusterZhongxiang Zhao, G. Ivan MaldonadoThe MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport[1]. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scientists … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Dec 2006 · 6,918 accessesView PDFCite
