Quantum Computing Advances At MIT - Trapping Rubidium Atoms In A Lattice Of Light
2014-04-11 04:29:35

redOrbit Staff & Wire Reports - Your Universe Online Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems. The researchers used a laser to place individual atoms of the metal rubidium near the surface of a lattice of light, allowing them to couple a lone atom with a single photon, or light particle. The system allows both the atom and photon to switch the quantum...

European Researchers Reveal The Physics Of The Secret
2014-03-27 14:02:50

[ Watch the Video: Keeping Secrets in a World of Spies and Mistrust ] Peter Suciu for redOrbit.com - Your Universe Online Is it really a secret if researchers share it? In the March 27 issue of Nature, the weekly international journal of science, researchers Artur Ekert and Renato Renner revealed what physics can tell us about keeping our secrets secret. This comes after high profile revelation that the National Security Agency (NSA) had been spying on emails, phone calls and other...

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

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...

Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU’s Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past. It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes...

Quantum World Record Crushed
2013-11-14 15:37:00

University of Oxford A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science a test performed by Mike Thewalt of Simon Fraser University, Canada, and colleagues. In conventional computers data is stored as a string of 1s and 0s. In the experiment quantum bits...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
