University of Vienna Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer – the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature...

D-Wave Quantum Computer Passes Important Computing Test
2013-05-09 17:57:32

Enid Burns for redOrbit.com – Your Universe Online Quantum computing just took a step from theory to practice with a test that took place at Amherst College in Massachusetts. An experimental quantum computer developed by D-Wave Systems was able to solve a problem 3,600 times faster than a conventional computer, the New York Times reports. Catherine McGeoch, the Beitzel Professor in Technology and Society in the computer science department at Amherst College administered the test. She...

Quantum Internet Prototype In Use At Los Alamos
2013-05-07 15:49:02

Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...

COLLEGE STATION, Texas, April 18, 2013 /PRNewswire-USNewswire/ -- In the bizarre world of quantum physics, objects can be in more than one place at a time and future events can change the past. New research involving a Texas A&M University professor makes that microscopic realm even a bit stranger. (Logo: http://photos.prnewswire.com/prnh/20120502/DC99584LOGO) Quantum physicist M. Suhail Zubairy, along with a post-doctoral fellow and Saudi researchers, have discovered a form...

To maneuver a car into a parking spot parallel to the road can be quite a challenge. It would be an easy task, of course, if only the vehicle could move sideways. As this is not possible, the sideways motion must be pieced together – sometimes elegantly, sometimes less so – in a series of forward and backward movements and turns on the steering wheel. Such a finely tuned sequence of movements also enables cats to almost always land on their feet after a free fall. Researchers at ETH...

Einstein's "Spooky Action" Theory Could Be Tested Aboard Space Station
2013-04-10 12:02:29

April Flowers for redOrbit.com - Your Universe Online "Spooky action at a distance" is how Albert Einstein rather famously described the theory of quantum entanglement. Until now, however, experiments attempting to examine this peculiar quantum mechanical phenomenon have been limited to relatively small distances on Earth. Researchers have proposed a solution to this in a new study published in the New Journal of Physics. To test the limits of Einstein's "spooky action" and potentially...

Rubidium Vapor Stores Visual Images
2013-04-04 19:22:16

Lee Rannals for redOrbit.com – Your Universe Online Scientists have demonstrated how they are able to store visual images within a thin vapor of rubidium atoms. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland reported in the New Journal of Physics about how they used the cloud of atoms as an optical memory device. The team believes their work could be helpful in creating memory for quantum...

German Researchers Take Next Step In Quantum Communications

Brett Smith for redOrbit.com - Your Universe Online Quantum-based communications is still in its infancy, but the technology is widely expected to become used as the next generation of secure data transfer. According to a new report in Nature Photonics, a group of German physicists has announced the successful transmission of a quantum security key from an aircraft to a ground station via laser, overcoming one of the technology’s biggest hurdles: the ability to transmit and receive...

Major Step Towards Quantum 'Internet' Signaled By Laser-like Photons
2013-03-19 13:30:09

University of Cambridge The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'. The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago. If this is to continue, conceptual and technical advances...
