14-11-12 Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority o...

14-11-05 Two USC researchers have proposed a link between string field theory and quantum mechanics that could open the door to using string field theory -- or a broader version of it, called M-theory -- as the basis of all physics. This could solve the myst...

14-10-30 A solution to one of the key challenges in the development of quantum technologies has been proposed by University of Sussex physicists. In a paper published today (28 October) in Nature Communications, Professor Barry Garraway and colleagues show h...

14-10-14 Spintronics is an emerging field of technology where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds with lower energy consumptio...

14-10-14 Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers. The teams created two types of quantum bits, or qubit...

14-10-04 Commercial devices capable of encrypting information in unbreakable codes exist today, thanks to recent quantum optics advances, especially the generation of photon pairs -- tiny entangled particles of light. Now, an international team of researcher...

14-09-16 The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what's called the Copenhagen i...

14-09-03 In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now Northwestern University scientists have figured out an elegant way to stop a molecule from tumbling so that its poten...

14-08-27 Decades of experiments have verified the quirky（古怪的） laws of quantum theory again and again. So when scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University of Roche...

14-08-21 For the first time, chemists have succeeded in measuring vibrational motion of a single molecule with a femtosecond（飞秒） time resolution. The study reveals how vibration of a single molecule differs from the behaviour of larger molecular groups....
