Florian Aigner, Vienna University of Technology Coupling atomic spins in diamonds to microwave resonators could lead to new quantum technologies. Researchers at the Vienna University of Technology (TU Wien) have now managed to dramatically prolong the time these systems can store information. The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of...

National Science Foundation University of Michigan computer scientist reviews frontier technologies to determine fundamental limits of computer scaling From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment and governance while shrinking to become ubiquitous handheld portals to the world. This progress has been driven...

Florian Aigner, Vienna University of Technology (TU Wien) A new kind of quantum computer is being proposed by scientists from the TU Wien (Vienna) and Japan (National Institute of Informatics and NTT Basic Research Labs). The Quantum Computer is the Holy Grail of quantum technology. Its computing power would eclipse even the fastest classical computers we have today. A team of researchers from TU Wien (Vienna) the National Institute for Informatics (Tokyo) and NTT Basic Research Labs in...

World’s First Photonic Router
2014-07-14 03:14:29

Weizmann Institute of Science Weizmann Institute scientists take another step down the long road toward quantum computers Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This achievement, as reported in Science magazine, is another step toward overcoming the difficulties in building quantum computers. At the core of the device is an atom that can...

Carefully fabricating nanofibers by heating and pulling may make for highly-efficient, optics-based, low-power atom traps WASHINGTON, June 17, 2014 /PRNewswire-USNewswire/ -- Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its melting point and then pull it apart. The middle will thin out like a piece of taffy until it is less than half a micron across -- about 200 times...

Alan McStravick for redOrbit.com - Your Universe Online The difficulty in understanding the field of quantum computing just got a little easier, but only slightly. New research from the University of Waterloo's Institute for Quantum Computing has confirmed, at least theoretically, that the concept of contextuality is a necessary resource required for achieving the advantages of quantum computation. Contextuality is regarded as one of the weirder aspects of quantum theory and is a...

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...

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...

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...
