| Playing quantum tricks with measurements Feb 17th 2013, 13:36 Physicists have performed an experiment that seems to contradict the foundations of quantum theory – at first glance. The team reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer. |  | 'Acoustic-assisted' magnetic information storage invented Feb 14th 2013, 19:18 Electrical engineers have discovered a way to use high-frequency sound waves to enhance the magnetic storage of data, offering a new approach to improve the data storage capabilities of a multitude of electronic devices around the world. | | New method to measure the redundancy of information Feb 14th 2013, 18:28 Understanding information as well as its redundancy, or duplication, has been crucial in the development of many of our everyday items such mobile phones, the internet, the compact disc as well as ensuring the success of many space missions. Using information geometry tools, researchers have developed a new mathematically precise method of measuring information redundancy. | |
