Scientists develop powerful method of suppressing errors in quantum computers

June 22nd, 2009 SYDNEY - Australian scientists have developed a new method for transmitting data with light that may lead to the development of teleportation technology and super-fast quantum computers. According to a report in www.news.com.au, the research team, from the Australian National University, developed a new approach to generating quantum entanglement in beams of light using only two parts.

July 31st, 2009 WASHINGTON - A Tel Aviv University researcher has claimed that the first quantum computer could overnight threaten our security and our data. Dr. Julia Kempe, of Tel Aviv University's Blavatnik School of Computer Science, says that these new computers, still in the theoretical stage, will be many times more powerful than the computers that protect our data now.

June 25th, 2009 WASHINGTON - Physicists have found that lasers can be used to drastically prolong the shelf life of quantum bit memory, the 0s and 1s of quantum computers, by 1,000 times. These precarious bits, formed in this case by arrays of semiconductor quantum dots containing a single extra electron, are easily perturbed by magnetic field fluctuations from the nuclei of the atoms creating the quantum dot.

August 10th, 2009 WASHINGTON - Physicists at the National Institute of Standards and Technology (NIST), US, have demonstrated sustained, reliable information processing operations on electrically charged atoms (ions), thus raising prospects for building a practical quantum computer. The new work overcomes significant hurdles in scaling up ion-trapping technology from small demonstrations to larger quantum processors.

June 29th, 2009 WASHINGTON - A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer. They also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with a solid-state device for the first time.

June 9th, 2009 WASHINGTON - A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. The Bristol Centre for Quantum Photonics has demonstrated precise control of four photons using a microscopic metal electrode lithographically patterned onto a silicon chip.

September 26th, 2009 LONDON - A team of scientists has designed a system that can fire barrages of entangled photons with machine-gun regularity, and can power quantum computers in the future. Existing methods of producing entangled photons tend to spew out photons more or less randomly, according to Terry Rudolph at Imperial College London.

September 30th, 2009 WASHINGTON - University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications like a quantum computer. Quantum dots-often called artificial atoms or nanoparticles-are tiny semiconductor crystals with wide-ranging potential applications in computing, photovoltaic cells, light-emitting devices and other technologies.

September 19th, 2009 WASHINGTON - Korean computer scientists have developed a novel security language for home networks that could ward off cyber attack in homes. Like companies, banks, and other big organizations, domestic and small office networks are just as vulnerable to hacking, malicious computer code, worms, viruses, and eavesdropping.

July 9th, 2009 LONDON - British scientists have developed a software program that can enable computers to learn sign language by watching TV. It learns sign language by absorbing TV shows that are both subtitled and signed.

July 8th, 2009 WASHINGTON - A cutting-edge face recognition software could revolutionize security systems, especially if it can see through disguises, according to the latest research. Every face has special features that define that person, yet faces can also be very similar, explained Lin Huang from Florida Atlantic University (FLA), in Boca Raton.

October 11th, 2009 LONDON - Though progressive in nature, yet highly sophisticated computer is no match to a child's common sense, as machines are not blessed with reasoning power. But artificial intelligence scientists are aspiring towards enabling computers to have human-level intelligence by developing a commonsense knowledge base.

May 12th, 2009 WASHINGTON - An approach based on the mathematical theory of elliptic curves may pave the way much more efficient cryptography - which underpins privacy, confidentiality, and identity to provide the fabric for e-commerce and secure communications - that will be capable of strengthening security against cyber crime and any terrorist attacks via the Internet. The RSA cryptosystem - introduced by Rivest, Shamir, and Adlement in 1977 - relies for its security on the difficulty of working out the factors dividing large integers.

September 4th, 2009 WASHINGTON - A new software, designed by optical scientists, is likely to revolutionise photography by teaching the camera new tricks. Its performance will then be no longer limited by the software pre-installed by the manufacturer.
