Key Takeaways
- Cov kws tshawb fawb hais tias kev siv cov khoom siv ob sab tuaj yeem ua rau lub khoos phis tawj nrawm dua.
- Qhov kev tshawb pom tuaj yeem yog ib feem ntawm kev hloov pauv tom ntej hauv thaj chaw uas suav nrog quantum computers.
- Honeywell tsis ntev los no tshaj tawm tias nws tau teeb tsa cov ntaub ntawv tshiab rau quantum ntim, ntsuas kev ua tau zoo tag nrho.
Kev nce qib hauv physics tsis ntev los no tuaj yeem txhais tau tias lub khoos phis tawj nrawm dua ua rau muaj kev hloov pauv hauv txhua yam los ntawm kev tshawb nrhiav tshuaj rau kev nkag siab txog kev hloov pauv huab cua, cov kws tshaj lij hais.
Cov kws tshawb fawb tau tshawb pom thiab kos duab cov khoom siv hluav taws xob hauv ib hom tshiab ntawm transistor. Qhov kev tshawb fawb no yuav ua rau cov khoos phis tawj nrawm dua uas siv cov khoom siv hluav taws xob zoo li qub tsis yog lawv cov nqi xwb. Qhov kev tshawb pom tuaj yeem yog ib feem ntawm kev hloov pauv tom ntej hauv thaj chaw uas suav nrog quantum computers.
"Quantum computers txheej txheem cov ntaub ntawv nyob rau hauv ib tug fundamentally txawv tshaj li classical computers, uas pab kom lawv daws tau tej teeb meem uas zoo unsolvable nrog niaj hnub classical computers," John Levy, co-founder thiab CEO ntawm lub quantum xam lub tuam txhab Seeqc, hais hauv kev xam phaj email.
"Piv txwv li, hauv kev sim ua los ntawm Google thiab NASA, cov txiaj ntsig tau los ntawm ib daim ntawv thov quantum tshwj xeeb tau tsim nyob rau hauv me me ntawm feeb piv rau kwv yees li 10,000 xyoo nws yuav siv lub supercomputer muaj zog tshaj plaws nyob rau hauv. ntiaj teb no."
Cov khoom siv ob sab
Nyob rau hauv qhov kev tshawb pom tsis ntev los no, cov kws tshawb fawb tau tshawb fawb thaj chaw tshiab hu ua spintronics, uas siv cov tshuab hluav taws xob tig los ua kev suav. Cov khoom siv hluav taws xob tam sim no siv cov nqi hluav taws xob los ua kev suav. Tab sis kev saib xyuas cov kiv ntawm electrons tau ua pov thawj nyuaj.
Ib pab pawg coj los ntawm Division of Materials Science ntawm University of Tsukuba thov kom tau siv electron spin resonance (ESR) los saib xyuas tus naj npawb thiab qhov chaw ntawm qhov tsis muaj kev sib tw txav los ntawm molybdenum disulfide transistor. ESR siv tib lub hauv paus ntsiab lus ntawm lub cev raws li cov tshuab MRI uas tsim cov duab kho mob.
"Xav txog kev tsim lub quantum computer daim ntawv thov txaus los simulate kev nyab xeeb thiab kev ua tau zoo ntawm kev sim tshuaj-tsis tau sim lawv ntawm tus neeg tiag."
Txhawm rau ntsuas lub transistor, lub cuab yeej yuav tsum tau txias kom tsuas yog 4 degrees saum toj kawg nkaus xoom. "Lub ESR cov cim qhia tau raug ntsuas ib txhij nrog lub qhov dej ntws thiab lub qhov rooj," xibfwb Kazuhiro Marumoto, tus kws sau ntawv ntawm txoj kev tshawb fawb, tau hais hauv xov xwm tshaj tawm.
Ib qho chaw hu ua molybdenum disulfide tau siv vim nws cov atoms tsim ib qho ze li ntawm ob sab (2D) qauv. "Kev ntsuas theoretical txuas ntxiv txheeb xyuas lub hauv paus pib ntawm kev sib tw," xibfwb Małgorzata Wierzbowska, lwm tus kws sau ntawv, tau hais hauv xov xwm tshaj tawm.
nce qib hauv Quantum Computing
Quantum suav yog lwm thaj chaw ntawm kev suav uas nce nrawm nrawm. Honeywell tsis ntev los no tshaj tawm tias nws tau teeb tsa cov ntaub ntawv tshiab rau quantum ntim, ntsuas ntawm kev ua tau zoo tag nrho.
"Qhov kev ua tau zoo no, ua ke nrog kev ntsuas qis nruab nrab ntawm lub voj voog, muab lub peev xwm tshwj xeeb uas cov neeg tsim khoom quantum algorithm tuaj yeem tsim kho tshiab," lub tuam txhab tau hais hauv kev tshaj tawm.
Thaum cov khoos phis tawj classical cia siab rau binary khoom (ib qho lossis xoom), quantum computers txheej txheem cov ntaub ntawv ntawm qubits, uas vim yog quantum mechanics, tuaj yeem muaj nyob ntawm ib lossis xoom lossis ob qho tib si tib lub sijhawm-exponentially nce ua lub zog, Levy hais.
Quantum khoos phis tawj tuaj yeem ua haujlwm ntawm cov teeb meem kev tshawb fawb thiab kev lag luam tseem ceeb yav dhau los xav tias yuav ua tsis tau, Levy tau hais. Qhov ntsuas ceev ib txwm zoo li megahertz tsis siv rau quantum xam.
Qhov tseem ceeb ntawm quantum computers tsis yog hais txog kev ceev ntawm txoj kev uas peb xav txog kev ceev nrog cov computers ib txwm muaj. "Qhov tseeb, cov khoom siv no feem ntau ua haujlwm ntawm qhov nrawm dua li quantum computers," Levy hais.
"Lub ntsiab lus yog tias quantum computers tuaj yeem khiav ib qho ntawm cov teeb meem kev tshawb fawb thiab kev lag luam uas yav dhau los xav tias yuav ua tsis tau."
Yog tias quantum computers puas tau ua tau zoo, txoj hauv kev thev naus laus zis tuaj yeem cuam tshuam tib neeg lub neej los ntawm kev tshawb fawb thiab kev tshawb pom tsis muaj qhov kawg, Levy hais.
"Xav txog kev tsim lub quantum computer daim ntawv thov txaus los simulate kev nyab xeeb thiab kev ua tau zoo ntawm kev sim tshuaj-tsis tau sim lawv ntawm tus neeg tiag tiag," nws hais.
"Los yog ib daim ntawv thov quantum computer uas tuaj yeem sim tag nrho cov qauv hauv ecosystem, pab peb tswj tau zoo dua thiab tiv thaiv cov teebmeem ntawm kev hloov pauv huab cua."
Cov khoos phis tawj quantum thaum ntxov twb muaj lawm, tab sis cov kws tshawb fawb tau tawm tsam nrhiav kev siv rau lawv. Levy tau hais tias Seeqc npaj yuav xa hauv peb lub xyoos "quantum architecture uas tau tsim nyob ib puag ncig cov teeb meem hauv ntiaj teb tiag tiag thiab muaj peev xwm ntsuas kom tau raws li cov kev xav tau ntawm kev lag luam."
Quantum computers yuav tsis muaj rau cov neeg siv nruab nrab xyoo, Levy tau hais. "Tab sis cov ntawv thov kev lag luam rau cov thev naus laus zis tau ua rau lawv tus kheej pom meej hauv cov ntaub ntawv siv kev lag luam xws li kev tsim kho tshuaj, kev tsim kho kom zoo, thiab quantum chemistry," nws hais ntxiv.
