Segundo consta: ".Actual major problem in the field of microchips, it is heating. Any modern PC is so barded of systems of cooling. This situation could change before some years, according to recent results published in the magazine Science. The laboratory of Almaden d' IBM, in California, works in effect to conceive an archetype of CPU (central processor) conceived by nano-technology which could eventually be of a size 260 000 times lower in the actual processors! How is it possible? Technology leans on a recent methode of measure of " the spectroscopy of the spin ", what will indeed speak to our physical friends. More concrétement, it is a question of using a quantum ownership of the material similar to polarization. By reversing this nuclear "polarity", they acquire the smallest possible transistors. At least until they attack nuclear core itself. By coupling a microscope with effect tunnel with powerful supraconducteurs magnets, IBM Research asserts being capable of controlling the spin particulaire by producing a 140 000 times as powerful magnetic field as that of the Earth. Result is a coat of registered atoms of manganese one after another on a coat of copper (see illustration). IBM moves then the atoms of manganese, which act as switches on the chains of atoms when the number of atoms of a chain passes hand in hand to odd. They find the principle of the transistor. It is therefore urgent of true nano-processors which will go out of laboratories of the American giant. At the same time, in Europe not, nothing. Two "small" flats to be nevertheless added: first as all leading-edge technologies, technique remains costly extrèmement, therefore even if they succeed in putting in the same surface as actual CPU 260 000 nano-processors, it would be necessary that each of them is almost 260 000 times less dear. Otherwise IBM risks d " sell 260 000 less than Finally, and second problem, more ironic: if these processors are in priori called to heat up much less, owing to quasi absence of heating thermodynamics, it will really be necessary to work on cooling. In effect, to move atoms, unit must work for the time being on a temperature of even... 0,5 ° Kelvin () - 272,65°C. This gets cold not? ..." lá está.. IBM on the lead..
