Low-Power Computing Discovery

Authors: George Rajna
Comments: 94 Pages.

"The atom-scale devices we are developing create a new basis for computer electronics that will be able to run at least 100 times faster or operate at the same speed as today but using 100 times less energy," continued Wolkow. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits—utilising the spin-orbit coupling of atom qubits—adding a new suite of tools to the armory. [51] A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. [50] Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons. [49] Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. [48] Researchers from Intel Corp. and the University of California, Berkeley, are looking beyond current transistor technology and preparing the way for a new type of memory and logic circuit that could someday be in every computer on the planet.

Without Waste Heat Supercomputer

Authors: George Rajna
Comments: 85 Pages.

Combining the lossless charge transport of superconductivity with the electronic transport of magnetic information, i.e., spintronics, paves the way for fundamentally novel functionalities for future energy-efficient information technologies. [45] The interactions of quarks and gluons are computed using lattice quantum chromodynamics (QCD)—a computer-friendly version of the mathematical framework that describes these strong-force interactions. [44] The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. [43] In a recent experiment at the University of Nebraska–Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light. [42] Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning—all in a package that's around a thousandth of the size of current accelerators. [41] The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities. [40] The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said. [38]

Intrusion Detection System and Neutrosophic Theory for MANETs: A Comparative Study

Authors: Haitham ElWahsh, Mona Gamal, A. A. Salama, I.M. El-Henawy
Comments: 7 Pages.

. Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organized in arbitrary and temporary network topologies without communication infrastructure. This network may change quickly and unforeseeable. The unique characteristics of MANET give an adversary the opportunity to launch numerous attacks against ad-hoc networks. So the security is an important role in MANETs. This article aims to present the concept of intrusion detection system (IDs) and surveys some of major intrusion detection approach against neutrosophic intrusion detection system in MANETs. Current IDS’s corresponding to those architectures are also reviewed and compared. This paper introduces the accuracy rate and false alarm rate of four completely different classifiers to observe the percentage and the efficiency of the classifiers in detecting attacks in MANETs. Results show that Neutrosophic intelligent system based on genetic algorithm could facilitate significantly in detecting malicious activities in MANETs. Hence, neutrosophic techniques could be utilized to suit the ambiguity nature of the IDs

Faster Computer Memory Devices

Authors: George Rajna
Comments: 78 Pages.

A team of scientists from Arizona State University's School of Molecular Sciences and Germany have published in Science Advances online today an explanation of how a particular phase-change memory (PCM) material can work one thousand times faster than current flash computer memory, while being significantly more durable with respect to the number of daily read-writes. [46] A new two-qubit quantum processor that is fully programmable and single electron spins that can be coherently coupled to individual microwave-frequency photons are two of the latest advances in the world of solid-state spin-based quantum computing. [45] Scientists at the National Institute of Standards and Technology (NIST) have now developed a highly efficient converter that enlarges the diameter of a HYPERLINK "https://phys.org/tags/light/" light beam by 400 times. [44] There's little doubt the information technology revolution has improved our lives. But unless we find a new form of electronic technology that uses less energy, computing will become limited by an "energy crunch" within decades. [43] Researchers at the Niels Bohr Institute, University of Copenhagen, have recently succeeded in boosting the storage time of quantum information, using a small glass container filled with room temperature atoms, taking an important step towards a secure quantum encoded distribution network. [42] New work by a team at the University of Bristol's Centre for Quantum Photonics has uncovered fundamental limits on the quantum operations which can be carried out with postselection. [41] The experimental investigation of ultracold quantum matter makes it possible to study quantum mechanical phenomena that are otherwise inaccessible. [40] The molecular switch is the fruit of a collaboration of members from the Departments of Experimental and Theoretical Physics at the University of Würzburg: Dr. Jens Kügel, a postdoc at the Department of Experimental Physics II, devised and ran the experiments. [39] A new test to spot where the ability to exploit the power of quantum mechanics has evolved in nature has been developed by physicists at the University of Warwick. [38]
