Key Takeaways
- Cov kws tshawb fawb hais tias qhov kev ua tiav ntawm kev siv lub teeb xa cov ntaub ntawv tuaj yeem ua rau cov khoom siv hluav taws xob tsawg heev.
- Cov kws tshawb fawb tau siv hom tshiab semiconductor los tsim cov quantum dots txheej zoo li lub thawv qe.
- Kev tshawb fawb tshiab yog ntawm cov tswv cuab ntawm cov thev naus laus zis tshiab uas tuaj yeem tso cai rau cov khoom siv hluav taws xob qis qis.
Qhov kev tawg tsis ntev los no hauv kev xa cov ntaub ntawv siv lub teeb tuaj yeem ua rau cov khoom siv hluav taws xob tsawg heev.
Cov kws tshawb fawb tau pom tias lawv tuaj yeem siv cov txiaj ntsig quantum hu ua nonlinearity los hloov kho thiab pom cov teeb liab tsis muaj zog. Txoj kev loj hlob thaum kawg tuaj yeem siv rau hauv cov khoom siv hluav taws xob tus kheej. Tab sis tsis txhob cia siab tias yuav pom quantum gadget hauv Qhov Zoo Tshaj Yuav txhua lub sijhawm sai sai.
"Txoj kev piav qhia hauv tsab xov xwm no yog qhov cuam tshuam thiab zoo siab, tab sis nws zoo li nyob deb ntawm kev xa mus," Scott Hanson, tus tsim thiab tus thawj coj thev naus laus zis ntawm Ambiq, lub tuam txhab tshwj xeeb hauv cov khoom siv hluav taws xob tsawg, hais hauv kev xam phaj email.
"Cov chips siv nyob rau hauv cov khoom siv tshiab niaj hnub no yog ua raws li tib yam silicon-raws li 'hloov' uas tau nyob ib puag ncig ntau xyoo lawm. Txawm tias me me hloov pauv rau txoj kev cov chips no tau tsim siv ntau xyoo los siv."
Quantum cuam tshuam ua rau Discovery
Cov kws tshawb fawb tau siv hom tshiab ntawm semiconductor los tsim quantum dots teem zoo li lub thawv qe. Pab neeg no tsim lub qe thawv lub zog toj roob hauv pes nrog ob lub flakes ntawm semiconductor, uas yog suav tias yog cov khoom siv ob sab vim tias lawv tau ua los ntawm ib txheej molecular, tsuas yog ob peb atoms tuab.
Ob-dimensional semiconductors muaj cov khoom quantum uas txawv ntawm cov chunks loj, thiab tuaj yeem siv rau hauv cov khoom siv hluav taws xob tsawg.
Rau qhov no kom muaj kev ruaj ntseg, peb yuav tsum nrhiav txoj hauv kev los tiv thaiv roj teeb lub neej-uas txhais tau tias khiav hluav taws xob tsis muaj zog.
"Cov kws tshawb fawb tau xav paub seb puas tuaj yeem kuaj pom cov teebmeem tsis zoo tuaj yeem txhawb nqa ntawm lub zog qis qis-txog rau ib tus neeg photons. Qhov no yuav coj peb mus rau qhov qis qis ntawm kev siv hluav taws xob hauv kev ua cov ntaub ntawv, "Hui Deng, tus kws tshaj lij physics. thiab tus kws sau ntawv laus ntawm cov ntawv hauv Xwm piav qhia txog kev tshawb fawb, tau hais hauv xov xwm tshaj tawm.
Ib qho kev sib tw tseem ceeb uas cov kws tshawb fawb yuav tsum tau kov yeej yog yuav ua li cas tswj cov quantum dots. Txhawm rau tswj cov dots ua ib pab pawg nrog lub teeb, pab pawg tsim lub resonator los ntawm kev ua ib daim iav rau hauv qab, tso lub semiconductor rau saum nws, thiab tom qab ntawd tso ib daim iav thib ob rau saum lub semiconductor.
"Koj yuav tsum tswj lub thickness nruj heev kom cov semiconductor nyob rau ntawm qhov siab tshaj plaws ntawm qhov kho qhov muag," Zhang Long, tus kws tshawb fawb tom qab kawm tiav hauv Deng's lab thiab thawj tus sau ntawm daim ntawv, tau hais hauv xov xwm tshaj tawm.
Tus tshiab 2D semiconductors tuaj yeem nqa cov khoom siv quantum mus rau chav tsev kub ntau dua li qhov txias txias uas tam sim no xav tau.
"Peb tab tom los txog rau qhov kawg ntawm Moore Txoj Cai," said Steve Forrest, tus kws tshaj lij engineering thiab tus kws sau ntawv ntawm daim ntawv, hais txog qhov sib txawv ntawm qhov ceev ntawm cov transistors ntawm ib nti ob npaug txhua ob xyoos, hauv xov xwm tshaj tawm.
"Cov ntaub ntawv ob sab muaj ntau yam khoom siv hluav taws xob thiab kho qhov muag zoo siab uas yuav, qhov tseeb, coj peb mus rau thaj av ntawd dhau silicon."
Yog tias Deng qhov kev tshawb fawb them nyiaj, Ultra-Low Power Devices (ULPD) tuaj yeem muaj txiaj ntsig zoo rau cov neeg siv, Charlie Goetz, CEO ntawm Powercast, lub tuam txhab hluav taws xob wireless, tau hais hauv kev xam phaj email."Lawv yuav ua kom muaj kev sib txuas ntawm IoT nyob rau txhua qhov chaw kom teeb tsa thiab siv tau. Cov no, dhau los, yuav pub AI, uas tuaj yeem hloov pauv qhov ntau ntawm cov tswv yim rau hauv cov zis zoo," nws hais ntxiv.
"ULPDs yuav yog qhov ua tau zoo uas yuav tsav-greener, nyab xeeb dua, muaj txiaj ntsig zoo-ntse lub nroog yav tom ntej."
Tshawb nrhiav ntau txoj hauv kev kom tsis muaj zog
Cov kws tshawb fawb tab tom tshawb nrhiav lwm cov thev naus laus zis uas tuaj yeem tso cai rau cov khoom siv hluav taws xob qis qis.
"Muaj kev nce qib zoo hauv System ntawm Chip (SoC) qhov chaw nyob ob peb xyoos dhau los," Goetz tau hais. "Cov cuab yeej siv hluav taws xob qis no tuaj yeem ua haujlwm tau ntau xyoo ntawm lub roj teeb thiab, qhov tseem ceeb dua, tuaj yeem siv wirelessly ntawm qhov deb siv xov tooj cua zaus lossis qee zaus, infrared."
Tib neeg haiv neeg tab tom ua luam dej hauv cov roj teeb ntawm lub xov tooj smartphone kom tua hluav taws, Hanson tau hais. Nws hais ntxiv tias "Qhov no tau dhau los ua tsis yooj yim vim tias peb cov khaub ncaws, tsev, thiab lub nroog nyob ib puag ncig peb txhua tus tau ua 'ntse' thiab 'txuas ntxiv," nws hais ntxiv.
Rau qhov no kom muaj kev ruaj ntseg, peb yuav tsum nrhiav txoj hauv kev los khaws cov roj teeb lub neej-uas txhais tau tias khiav hluav taws xob nrog lub zog tsawg dua.
