(PhysOrg.com) -- Groundbreaking research in quantum light source led by the University of Sydney will result in information speeds many times faster and data that is almost impossible to hack.

(PhysOrg.com) -- When it comes to quantum measurements, interaction with the environment usually limits sensitivity, since it causes decoherence. But in a new study, scientists have shown that the environment can be advantageous.

(PhysOrg.com) -- The development promises significant improvements in optical data processing and transmission and other technologies.

(AP) -- The world's biggest particle physics lab on Tuesday played down claims of a major discovery, after a leaked memo hinting that the elusive Higgs boson - or 'God particle' - may have been found ricocheted around science websites.

When it comes to dreaming about diamonds, energy efficiency and powerful information processing aren't normally the thoughts that spring to mind. Unless, of course, you are a quantum physicist looking to create the most secure and powerful networks around.

(PhysOrg.com) -- The power and resolution of lens-based optical microscopes have improved by orders of magnitude since their invention around 1595. Nevertheless, relying on a high-magnification lens for image clarity has limitations that become more relevant as larger and larger sample volumes need to be viewed

Scientists at the Naval Research Laboratory Plasma Physics Division demonstrate significant progress in the efficiency and cost effectiveness of light ions in the fast ignition of fusion targets. Light ions such as lithium or carbon are easier to produce technologically and the ion beam properties can be manipulated and tailored best to suit the necessary requirements for fast ignition.

(PhysOrg.com) -- With the Large Hadron Collidor (LHC) running smoothly for well over a year now, the excitement surrounding the possibility for the discovery of new physics has generated a few rumors - speculations that have not been published in peer-reviewed journals. The latest came last week, when an anonymous person posted the abstract of a note on Columbia University mathematician Peter Woit’s blog that claimed an intriguing observation.

Researchers at Rensselaer Polytechnic Institute have developed a new method for manufacturing green-colored LEDs with greatly enhanced light output.

The ants may go marching one by one, but they end up forming a superstructure of thousands -- and together they can form a raft that stretches the boundaries of the laws of physics, according to new research released today.

Costa Rica was once regarded as the poorest of all the colonies of the Spanish Empire, sadly deficient in the silver and gold so coveted by conquistadors. As it turns out, all of the glittering gold and silver those explorers could have ever wanted was there all along, in the country's tropical rainforests—but in the form of two gloriously lustrous species of beetle.

(PhysOrg.com) -- The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time

(PhysOrg.com) -- An international team of researchers succeeded at the Max Planck Institute of Quantum Optics to control and monitor strongly accelerated electrons from nano-spheres with extremely short and intense laser pulses. (Nature Physics, 24

Physicists at Rice University and their collaborators have detected the antimatter partner of the helium nucleus, antihelium-4. This newly observed particle is the heaviest antimatter particle ever detected.

Ensuring a pound of butter is indeed a pound, or a gallon of milk a full gallon, has long been the province of government agencies that deal with weights and measures. But now it seems scientists are having a little trouble with the golf-ball-size piece of metal that is used to set the standard weight for a kilogram, or kilo.
