Quantum suav chips loj heev kom ceev tshuab-kev kawm

Canada's D-Wave, lub ntiaj teb thawj lub tuam txhab kev lag luam quantum suav, tau ua cov kauj ruam tseem ceeb rau lub neej tom ntej ntawm kev ua haujlwm nrawm, nrog tsuas yog cov neeg ua haujlwm txo qis ntawm 140 tus neeg ua haujlwm.

PC World qhia uas D-Wave tsim nws thawj quantum computer nyob rau hauv 2011. Txij thaum ntawd los, nws tau raug muag rau ntau lub koom haum xws li Lockheed Martin thiab NASA. Raws li Tech Republic, D-Wave tau sau ntau lab daus las hauv kev nqis peev los ntawm ntau pawg, xws li Goldman Sachs thiab Asmeskas C.I.A.

D-Wave quantum computer raug nqi ntau dua $15 lab, tshaj tawm Tus Saib Xyuas. Lub vev xaib D-Wave tau tshaj tawm nws cov khoom lag luam zoo li "lub siab tshaj plaws quantum computer nyob rau hauv lub ntiaj teb no."

Lub khoos phis tawj siv niaj hnub theoretical physics discoveries thiab "kais ncaj qha rau hauv cov ntaub ntawv tseem ceeb ntawm kev muaj tiag." Nws yog ib qho tseem ceeb muaj feem xyuam rau lub tswv yim ntawm quantum superposition - lub peev xwm ntawm ib tug hais kom muaj nyob rau hauv ntau lub xeev sib txawv nyob rau tib lub sij hawm - thiab lub peev xwm ntawm quantum ntsuas los xav txog ntau yam ua ke ntawm classical physics ntsuas ib txhij.

Suab txawv me ntsis? Cia Prime Minister Trudeau piav qhia!

Raws li Thawj Kav Tebchaws Trudeau tau piav qhia, es tsis txhob sau cov ntaub ntawv hauv binary daim ntawv (ib 1 lossis 0), quantum computer tuaj yeem sau ntau qhov muaj peev xwm hauv "qubits" - uas tuaj yeem yog 1 lossis 0. or kev sib xyaw ntawm ob qhov tseem ceeb. Kev suav ntawm cov txiaj ntsig no tshwm sim ib txhij thiab ua rau kaum tawm txhiab tus lus teb hauv vib nas this.

Lub D-Wave quantum computer muaj ntau dua ib txhiab qubits, thiab cov ntaub ntawv khaws cia muaj peev xwm nce exponentially.

Lub computer quantum tsuas tuaj yeem ua tiav cov kev suav hauv ib puag ncig nruj tswj hwm - uas yog, txias heev thiab siab. Cov cuab yeej siv niobium transistors uas tau txias kom tsis muaj xoom (400x txias dua li qhov chaw sab nrauv) los ntawm kev siv cov kua helium. Cov cua kub ntau dhau los yog tsuas yog lub teeb tuaj yeem cuam tshuam cov kev suav.

Raws li tus lwm thawj coj ntawm D-Wave, Jeremy Hilton, nyob rau hauv ob mus rau peb xyoos D-Wave yuav tau tsim ib lub computer loj dua quantum. Hmoov tsis zoo, qhov no tsis zoo ib yam li kev lag luam hauv computer, thiab quantum xam yuav tsum tau universalized kom npaj rau tus kheej siv.

D-Wave tau ua ob npaug ntawm qubits hauv nws cov quantum computers kwv yees li ib xyoos ib zaug, sau tseg D-Wave tus thawj coj ntawm kev txhim kho kev lag luam thiab kev sib koom tes, Colin Williams.

John Morton, tus xibfwb ntawm nanoelectronics thiab nanophotonics ntawm UCL tau hais tias thawj lub khoos phis tawj thoob ntiaj teb quantum yuav tsis muaj tsawg kawg yog kaum xyoo. Lub neej yav tom ntej yuav ua li cas rau ib tsev neeg zoo tib yam thaum xws li astronomical xam hwj chim thaum kawg tau npaj txhij?
