What if computers were able to function without electricity? American researchers from the university of Notre Dame in Indiana have proved that we can manipulate electrons in order to build circuits using small quantities of energy. Their experiments, as described in the Science magazine’s 9th of April issue pave the way for components able to function at a frequency 10 to 100 times higher than current chips prone to heat dissipation problems. The work of the research team lead by Greg Snider focuses on quantum wells, an infinitesimal trap in which the electrons can be sealed in. Scientific researchers have created square-shaped cells formed by four quantum wells in which a pair of electrons is introduced. Repulsion causes the electrons to move and find their balance once that they are located at the two extremities of each cell diagonally facing each other. The first cell represents 0 value, the second one represents 1. Each cell therefore represents one bit, the smallest amount of information that computers can handle. All movement of an electron created by an external force will automatically cause the another electron to move to maintain balance, thus the alternation between value 0 and 1. The use of one unique cell does not prove anything. American researchers managed to assemble many of them causing electrons to move without energy. For present-day transistors, the alternation between 0 value and 1 is only possible by using thousands of electrons generally causing heat to accumulate. By regrouping five basic cells, researchers have perfected a circuit dubbed "superior", capable of effectuating basic logic when asked to do so. They then made sure that this worked effectively hoping to later assemble many circuits in order to execute additions and multiplications. If they succeed, this technique of logic quantum cells will be used to heap hundreds of billions of circuits in one electronic chip. For the moment this device only works at temperature 0 however. However researches are desperately finding ways to increase its temperature while maintaining its temperature and mastering its behaviour. The billets of the company IV from the school of infantry recruits and exploration and transmission 213 located in Avenches, is invaded by lice and fleas. Bites from fleas have been found on more than one third of the soldiers. Dead lice have been found on 3 soldiers. In reaction to this, urgent measures have been taken. Bites from lice have been found on more than one third of the 155 men of the company IV from the school of infantry recruits and exploration and transmission 213. Dead lice were found, however no eggs were detected on the three soldiers. These insects are transmitted by personal contact. The cause of this insect invasion remains unclear, these insects seem to have swarmed the guard room. The medic immediately prescribed the medicine necessary to the soldiers concerned and he imposed strict hygiene rules. Special products were given out for body care. All personal equipment was hermetically bagged and brought to the cantonal arsenal of Fribourg. The troops were relocated in an industrial complex. A hygiene section in the school of recruits of the hospital 268 located in Moudon will disinfect the billets. Hopefully, with these measures the troops will be able to re-inhabitate their billets Friday at most.
