Scientists Watch a Chemical Bond Break Using Molecule's Electrons
July 28, 2010 Scientists followed a bromine chemical bond as it broke apart using an image that was obtained from a single molecular orbital. The experiment used an attosecond-duration X-ray burst to take a ... > full story -
More Accurate Than Heisenberg Allows? Uncertainty in the Presence of a Quantum Memory
July 27, 2010 Quantum cryptography is the safest way to encrypt data. It utilizes the fact that transmitted information can only be measured with a strictly limited degree of precision. Scientists have now ... > full story -
Position-Based Quantum Cryptography: New Method for Securing Location-Sensitive Data
July 26, 2010 Computer scientists have proved that cryptography, the practice and study of hiding information, based solely on location is possible by using quantum mechanics. This allows one to encrypt and ... > full story -
Quantum Mechanics Not in Jeopardy: Physicists Confirm a Decades-Old Key Principle Experimentally
July 22, 2010 When waves -- regardless of whether light or sound -- collide, they overlap creating interferences. Austrian and Canadian quantum physicists have now been able to rule out the existence of ... > full story -
Quantum Entanglement in Photosynthesis and Evolution
July 21, 2010 Recently, academic debate has been swirling around the existence of unusual quantum mechanical effects in the most ubiquitous of phenomena, including photosynthesis, the process by which organisms ... > full story -
New Quantum State of Matter Discovered in Heusler Compounds: Applications in Spintronics, Quantum Computing and New Physical Effects
July 20, 2010 Scientists have been researching Heusler compounds, which are an important material class for the use in spintronic applications. Over the past few years, new application areas have emerged in the ... > full story -
Advance Made Toward Communication, Computing at 'Terahertz' Speeds
July 19, 2010 Physicists in the United States and Germany have discovered a way to use a gallium arsenide nanodevice as a signal processor at "terahertz" speeds, the first time it's been used for this purpose and ... > full story -
A Simple Quantum Dynamics Problem?
July 14, 2010 New research provides the first real-time measurements of the time dependence of the individual steps of dissociation of a complex consisting of two rare gas atoms and a halogen ... > full story -
The Proton -- Smaller Than Thought: Scientists Measure Charge Radius of Hydrogen Nucleus and Stumble Across Physics Mysteries
July 12, 2010 Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimetre. This is precisely the ... > full story -
New Ultrabright Source of Entangled Photon Pairs
July 9, 2010 At the very heart of applications such as quantum cryptography, computation and teleportation lies a fascinating phenomenon known as "entanglement". Two photons are entangled if the properties of one ... > full story
