Scientists Explore Ways To Synchronize Magnetic Spins For More Powerful Nanoscale Electronic Devices
2014-04-30 03:07:24

Brookhaven National Laboratory Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work, published in Nature Communications, shows that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper can be driven to operate in unison, potentially producing a powerful...

Superconducting Qubit Array Points The Way To Quantum Computers
2014-04-24 03:15:00

Julie Cohen, UC Santa Barbara A new five-qubit array from UCSB’s Martinis Group is on the threshold of making a quantum computer technologically feasible to build A fully functional quantum computer is one of the holy grails of physics. Unlike conventional computers, the quantum version uses qubits (quantum bits), which make direct use of the multiple states of quantum phenomena. When realized, a quantum computer will be millions of times more powerful at certain computations than...

Diamonds Help Speed Up Spintronics
2014-03-26 04:49:49

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Ohio State University have demonstrated for the first time that information can flow through a diamond wire. Scientists are working to develop “spintronics” in order to make computers simultaneously faster and more powerful. Spin could be used to help transmit data in computer circuits, and the latest research shows just how viable of an option diamonds could be. The team wrote in the journal Nature...

Cryptography Scheme Secured By Quantum Physics
2014-03-12 14:30:34

Centre for Quantum Technologies The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the internet and in everyday life, for example at a bank's ATM. "Having quantum cryptography to hand is a realistic prospect, I think. I expect that quantum technologies will gradually become integrated with existing...

D-Wave Chip Passes Rigorous Tests
2014-03-05 13:50:44

University of Southern California With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended. The USC Viterbi School of Engineering is home to the USC-Lockheed Martin Quantum Computing Center (QCC), a super-cooled, magnetically shielded facility specially built to house the first commercially available quantum computing processors – devices so advanced that there are only two in use outside the Canadian lab where they were...

Quantum Technology The Next Level Of NSA Snooping
2014-02-01 04:37:32

Enid Burns for redOrbit.com - Your Universe Online Over the past several months, news has continued to leak about the extent that the US National Security Agency (NSA) has gone to spy on the public both abroad and domestic. Much of the news has stemmed from documents revealed by NSA contractor Edward Snowden. While the Obama administration has made statements that the NSA will back off from its surveillance efforts, news has come out that the government agency is developing new tactics to...

Quantum Physics May Make Secure, Single-use Computer Memories
2014-01-16 14:47:31

National Institute of Standards and Technology (NIST) Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised away to make a security device that has proved notoriously difficult to build—a "one-shot" memory unit, whose contents can be read only a single time. The research, which Liu is presenting at this week's Innovations in...

NSA Builds Encryption Busting Super Computer
2014-01-03 11:20:30

Peter Suciu for redOrbit.com – Your Universe Online On Thursday The Washington Post reported that the National Security Agency (NSA) is now developing a computer that, if successful, could break into nearly every type of encryption that currently exists. This would include encryption programs used to protect banking, medical, business and government records throughout the world. The Washington Post attributes these findings to documents provided by former NSA contractor Edward...

Algorithm
2013-12-16 10:46:30

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states and eventually...
