QUANTIC COMPUTATION : VERY NEAR

http://es.youtube.com/watch?v=_KUMXe9gh7c




Video, Youtube: Comparison between conventional Computer and quantum computer where "atoms speak".
1) Top: On/Off, states of napthalocyanine molecule 2) Down: Schematic view of the switching process that involves 2 hydrogen atoms located in a cavity at the center of the molecule.


IBM, finishes announcing that they are in capacity to make computation and to store information to atomic level, fact that begins to approach us to the singularity (technological revolution without precedents), predicted by Ray Kurzweil for the year : 2050, accelerating also the unstop miniaturization of chips, predicted by the Law of Moore. With which massive appeareance of quantum computers, with more capacity of processing thanks to the phenomenon of superposition (addition of amplitude of interference waves, so that an object simultaneously has 2 or but values for an observable thing) and superspeed thanks to entanglement (operations of data between 2 or but objects –spatially separated- described by referring one to another), also begins to materialize itself. Although some do not perceive the importance of the news, it is enough to say that thanks to this knowledge we will have within few years: robots with brains equivalent to the humans: making trips to the space and populating planets, planning scientific researches, making workings of security, and so on).

I) R. Stanley Williams of Hewlett-Packard, says that a hybrid chip :of silicon and components on molecular scale is being manufactured (field programmable gate Array: F.P.G.A), that saves enormous space. With the use of the magnetism on nanotechnológic scale, a technique has been created to read and to write digital and simultaneously: “1s” and “0s” on individual atoms. Thus, an iron atom, could simultaneously be stored in a unique qbit of binary data (“0” and “1”), identified by the orientation of its magnetic field, basic conception to build superquick cuantic computers. Researchers of I.B.M/Almaden Research Center/San Jose, California, have observed by means of a scanning tunneling microscope, the iron and Manganese atom magnetic orientation to low temperatures, crucial fact to read, to write and to store digital information. II) Another group of researchers of I.B.M/Zurich, has obtained that 2 Hydrogen atoms (with atomic movements forward and backwards -creating 2 states- equivalent to “0” and “1”), work like switchs. Finally the same group injected an electrical charge to the interior of a molecule, transmitting the effect to a neighboring molecule, establishing the atomic possibility of extending in the future, the effect to trillons of atomic switches (entanglement), accelerating infinitely the trasmisión of information.

COMPUTACION CUANTICA :MUY CERCA.

La IBM, acaba de anunciar que está en capacidad de realizar computación y almacenar información a nivel atómico, hecho que empieza a acercarnos a la singularidad (revolución tecnológica sin precedentes), predicha por Ray Kurzweil para el año 2050, acelerando asimismo la indetenible miniaturización de chips, predicha por la Ley de Moore. Con lo que la masivización de computadoras cuánticas, con más capacidad de procesamiento merced al fenómeno de superposición (adición de amplitudes de ondas de interferencia, de modo que un objeto posea simultáneamente 2 o mas valores para una cantidad observable) y supervelocidad merced al entanglement (operaciones de datos entre 2 o mas objetos -espacialmente separados- descritos con referencia el uno de otro), empieza también a materializarse. Aunque algunos no perciban la importancia de la noticia, baste decir que merced a ello tendremos dentro de pocos años :robots con cerebros equivalentes al de humanos : realizando viajes al espacio y poblando planetas, planificando investigaciones cientificas, realizando labores de seguridad, de salvataje, etc).

Con el empleo del magnetismo a escala nanotecnológica, se ha creado una técnica para leer y escribir simultáneamente :“1s” y “0s” digitales, sobre átomos individuales.

Investigadores de I.B.M/Almaden Research Center/San Jose, California, han observado mediante un scanning tunneling microscope, la orientación magnética de átomos de Hierro y Manganeso, a bajas temperaturas, hecho crucial para leer, escribir y almacenar información digital. II) Otro grupo de investigadores de la I.B.M/Zurich, ha logrado que 2 átomos de Hidrógeno (con movimientos atómicos, de delante hacia atrás, creando 2 estados, equivalentes a “0” y “1”), funcionen como switchs. Finalmente el mismo grupo inyectó una carga eléctrica al interior de una molécula, trasmitiendo el efecto a una molécula vecina, estableciendo la posibilidad de extender el efecto a trillones de switches atómicos en el futuro (entanglement), acelerando infinitamente la trasmisión de la información.

Hi, this is not so related to your page, but it is the site you asked me 1 month ago about the abs diet. I tried it, worked well. Well here is the site

Still, for that great act we speak of Isaacs gratefully and remember him kindly; and he forges on, hoping to meet the football http://startso11.info/W%C5%82adys%C5%82aw+Jagie%C5%82%C5%82a.html somewhere again.. We have been able to show in another place how the composition of the apparatus from http://startso11.info/.pkl.html the two systems permits a subtilization even of the normal activity which would be impossible for a single system.. Gosh! said Uncle Billy, http://startso11.info/www.mp3+pobieranie.html regretfully.. But to what opposition or to http://startso11.info/Krzysztof+Filipek.html what diversity do we refer this whence? I think it is to the opposition between conscious daily life and a psychic activity remaining unconscious which can only make itself noticeable during the night.. Nervy say make him take http://startso11.info/ksi%C4%99gowo%C5%9B%C4%87+pozna%C5%84.html it.. I was not surprised http://startso11.info/foto+wp.html when, after breakfast, my wife invited the Bredes to walk with us to our view.. Thus, for instance, a woman dreamt of herself carrying a tall flower-stalk, as in the picture of the http://rebestal.info/czyszczenie+aut.html Annunciation (Chastity-Mary is her own name), but the stalk was bedecked with thick white blossoms resembling camellias (contrast with chastity: La dame aux Camelias).. Although the http://startso11.info/e-learning+AND+angielski.html future which the dream shows us is not that which will occur, but that which we would like to occur.. They were bowling along through another avenue of trees when the driver suddenly shouted, Whoa there! The horses were brought up with a jerk that was well nigh fatal to the assortment of http://startso11.info/kredyty+profireal.html dignity inside the coach.. Take the patient from http://startso11.info/opowiadaniaerotyczne.html whom I got the last dream about the three tickets for one florin fifty kreuzers.. Even as Atalanta might have dropped an apple behind her to tempt her pursuer to check http://startso11.info/www.menorca.es.html his speed, so Miss Hoogencamp left that fish-ball behind her, and between her maiden self and contamination.. the numerous http://startso11.info/www.sun-car.pl.html examples).. An hysterical woman identifies herself http://startso11.info/WPiA.html most readily--although not exclusively--with persons with whom she has had sexual relations, or who have sexual intercourse with the same persons as herself.. When her http://startso11.info/dupont.html repressed memories had rewakened a certain period when she was conscious that she did not love her husband, her symptoms disappeared, and therewith disappeared her resistance to the interpretation of the dream.. How did I play Uncle Mose? Major Talbot, passing through the hall, saw Miss Lydia's door open and stopped. http://startso11.info/LTL+G%C4%84SAWA.html. The best thing we can do http://startso11.info/kuchenka+mikrofalowa+do+zabudowy.html is to walk home.. Midnight found him sprawled http://startso11.info/systemy+zarz%C4%85dzania+firm%C4%85.html asleep beside his fire.. I never knew any of my children behave so http://startso11.info/www.czat.wp.pll..html before, said Mrs.. There it was, the Indian River, rippling idly in full http://startso11.info/produkcja+elektronicznych+materia%C5%82%C3%B3w+reklamowych.html sunlight, palmettos leaning over the water, palmettos standing as irregular sentries along the low, reeflike island which stretched away out of the picture.. Gideon followed her slowly. http://rebestal.info/codec.html..

Correctly your article helped me altogether much in my college assignment. Hats high to you post, will look progressive in behalf of more interdependent articles in a jiffy as its anecdote of my pet question to read.
