Xi-Jun Ren and Yang Xiang from Henan Universities in China, in collaboration with Heng Fan at the Institute of Physics of the Chinese Academy of Sciences, have produced a theory for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, in an article about to be published in EPJ D . This could have implications for quantum information processing methods used, for example, in message encryption systems.

The characteristic crack and bang of a gunshot blast may contain vital clues about a crime: who shot first, or even what type of firearm did the deed. But dozens of factors, from the angle and direction of the gun’s muzzle to the quality of the microphone, can change the way a gunshot sounds in a recording, making it difficult even for expert analysts to tell exactly what went down at the scene of the crime.

Missouri’s digital divide is growing, a trend that threatens to leave farmers and agribusiness ventures at a disadvantage unless federal policymakers make concerted efforts to improve technology infrastructure in rural communities and small towns, according to a new study by the Community Policy Analysis Center (CPAC), located in the Truman School of Public Affairs at the University of Missouri. The study shows that Missouri is significantly behind national averages for overall statewide broadband Internet access.

Engineering researchers at the University of Toronto have developed the world’s most efficient organic light-emitting diodes (OLEDs) on plastic. This result enables a flexible form factor, not to mention a less costly, alternative to traditional OLED manufacturing, which currently relies on rigid glass.

Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fibre-optic cable. These waves consist of countless billions of photons, which carry information down the fibre across continents.
