How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the DiVincenzo criteria. The prescription is pretty clear at a glance; yet in practice the physical implementation of a full-scale universal quantum computer remains an extraordinary challenge.
Professor Mikhail Shifman, recent Pomeranchuk prize winner, says that particle physicists are experiencing a crucial time. And he ought to know. Shifman has written several books on the history of elementary particle physics. "We are at a crossroads, we will go to the left or to the right or nowhere" Shifman says, referring to the fact that supersymmetry, the theory that states that there are superpartners for every known particle, has not yet been discovered at the Large Hadron Collider.
As the next step in advancing NASA’s asteroid initiative, the agency will host an Opportunities Forum March 26 at NASA Headquarters in Washington.
Scientists on the CDF and DZero experiments at the U.S. Department of Energy's Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.
The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from the Niels Bohr Institute, among others, have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II.
RIKEN, the University of Tokyo, and NIMS succeeded for the first time in generating and visualizing electron spin vortex state "skyrmion molecules" with topological charge 2 within a thin film of "La1+2xSr2-2xMn2O7," a layered manganese oxide which is a ferromagnetic material with uniaxial anisotropy.
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
A physicist who studies the origin and makeup of the universe is the next speaker for Indiana State University's 203-14 University Speakers Series.
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day.
A new high-accuracy calibration of the LUX (Large Underground Xenon) dark matter detector demonstrates the experiment's sensitivity to ultra-low energy events. The new analysis strongly confirms the result that low-mass dark matter particles were a no-show during the detector's initial run, which concluded last summer.
The idea to perform data processing with light, without relying on any electronic components, has been around for quite some time. In fact, necessary components such as optical transistors are available. However, up to now they have not gained a lot of attention from computer companies. This could change in the near future as packing densities of electronic devices as well as clock frequencies of electronic computers are about to reach their limits.
Honeywell today brought Nobel Laureate Eric A. Cornell to Centro de Ensenanza Tecnica y Superior (CETYS) University, Mexicali, for a two-day program of inspirational exchanges with students and faculty.
QD Vision, Inc., manufacturer of quantum dot Color IQ™ optical components for LCD displays, today released a new whitepaper, “Color Matters,” that examines the psychology and biology associated with color and its pivotal role in the perception of picture quality. The paper also explores the importance of HDTV’s newest product differentiator, full-gamut color, as a crucial driver for consumer picture quality differentiation.
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality — a 50-year-old theorem that, if violated by experiments, would mean that our universe is based not on the textbook laws of classical physics, but on the less-tangible probabilities of quantum mechanics.

Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.
