Quantum computers muaj lub peev xwm los hloov lub ntiaj teb, tab sis tam sim no lawv tsuas yog ua haujlwm ntawm qhov kub thiab txias, thiab cov tshuab cua txias yog kim. Ib pab neeg los ntawm University of Texas ntawm El Paso tau tsim cov khoom siv quantum tshiab uas tuaj yeem ua haujlwm ntawm chav tsev kub thiab yog 100 npaug ntau sib nqus dua hlau ntshiab. Nws yuav tsum tau siv los tsim quantum computers uas tuaj yeem ua haujlwm ntawm chav tsev kub. Cov ntaub ntawv cuam tshuam tau luam tawm nyob rau hauv qhov teeb meem tsis ntev los no ntawm Applied Physics Letters.
Tus thawj coj ntawm txoj kev tshawb fawb Ahmed Elkindi tau hais tias cov hlau nplaum muaj dav pom nyob rau hauv cov khoom siv xws li smartphones, tsheb thiab cov khoom siv hauv xeev (khoom siv uas khaws cov ntaub ntawv hauv computer). Hauv quantum computers, cov hlau nplaum yog siv los ua kom cov kev suav ua kom nrawm, tab sis lawv cov hlau nplaum muaj zog tsuas yog tshwm sim nws tus kheej ntawm qhov kub thiab txias. Yog li ntawd, quantum computers tam sim no yuav tsum ua haujlwm ntawm qhov kub tsis tshua muaj siab ntawm -272.78 degree - tsuas yog me ntsis siab dua li xoom (-273.15 degree ). Txhawm rau kom lub quantum computer ua haujlwm kom zoo, lub khoos phis tawj thiab txhua yam khoom siv yuav tsum tau txias, uas yog kim heev. Txhawm rau daws qhov teeb meem no, pab pawg Elkindi tau ua haujlwm tsim cov khoom sib nqus tshiab txij li xyoo 2019.
Ob lub hom phiaj ntawm pab pawg yog: muaj peev xwm ua haujlwm ntawm qhov kub thiab txias thiab ua los ntawm cov ntaub ntawv tsis tshua muaj hauv ntiaj teb. Elkindi tau taw qhia tias txhua cov hlau nplaum tam sim no yog tsim los ntawm cov khoom siv hauv ntiaj teb tsis tshua muaj, thiab lub ntiaj teb tsis tshua muaj cov khoom tshwj xeeb. Tom qab ob peb xyoos ntawm kev sim thiab ua yuam kev, pab neeg thaum kawg tsim cov khoom siv hlau nplaum tshiab. Lawv siv cov aminoferrocene thiab graphene los tsim cov khoom siv sib nqus quantum uas yog 100 npaug ntau sib nqus dua hlau ntshiab thiab tuaj yeem ua haujlwm ntawm chav tsev kub. Cov kws tshawb fawb ntseeg tias cov khoom siv tshiab tuaj yeem siv los tsim quantum computers ntawm chav tsev kub.
Txawm li cas los xij, cov kws tshawb fawb hais tias tseem muaj ntau txoj haujlwm yuav tsum tau ua. Ua ntej, cov khoom siv yog qhov nyuaj rau kev ua, yog li lawv tau ua haujlwm ntawm kev ua kom zoo rau kev npaj. Tsis tas li ntawd, lawv txuas ntxiv txhim kho cov khoom siv tau zoo.
