| Breakthrough in light sources for new quantum technology Posted: 29 Aug 2014 05:42 AM PDT One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers have now succeeded in creating a steady stream of photons emitted one at a time and in a particular direction. |
| Computer games give a boost to English Posted: 28 Aug 2014 10:53 AM PDT If you want to make a mark in the world of computer games you had better have a good English vocabulary. It has now also been scientifically demonstrated that someone who is good at computer games has a larger English vocabulary. |
| Posted: 28 Aug 2014 08:01 AM PDT Just two years ago, with the advent of a technique called direct measurement, scientists discovered they could reliably determine a system's wave function by "weakly" measuring one of its variables (e.g. position) and "strongly" measuring a complementary variable (momentum). Researchers have now taken this method one step forward by combining direct measurement with an efficient computational technique. |
