Ebe nchekwa kacha nta n'ụwa

Ndị ọkà mmụta sayensị IBM Almaden Laboratories ewepụtala modul ebe nchekwa magnetik kacha nta n'ụwa. Ọ nwere naanị 12 atom iron. A ga-eji modul ahụ wedata ngwaọrụ nchekwa ndọta dị adị. Ewubere modul ahụ niile site na iji microscope tunneling nke dị na ụlọ nyocha IBM na Zurich. A na-echekwa data ahụ site na microscope ọwara mmiri. Nke a ga-enye ngwọta maka kọmpụta quantum n'ọdịnihu. Mmepe nke usoro nrụpụta dị otú ahụ dị mkpa n'ihi na quantum physics kpebisiri ike na oghere magnetik nke bit ọ bụla, mgbe ị na-emepụta ebe nchekwa na ọkwa atọm, ga-emetụta mpaghara bit dị n'akụkụ, na-eme ka o sie ike ịnọgide na-enwe steeti e kenyere ya nke 0 ma ọ bụ 1.
