Key Takeaways
- Pob zeb diamond tuaj yeem siv ib hnub los khaws cov ntaub ntawv ntau.
- Cov kws tshawb nrhiav tab tom sim siv qhov txawv txav ntawm quantum mechanics los tuav cov ntaub ntawv.
- Txawm li cas los xij, cov kws tshaj lij hais tias tsis txhob cia siab tias yuav muaj quantum hard drive hauv koj lub PC sai sai no.
Pob zeb diamond tej zaum yuav yog tus yuam sij rau khaws cov ntaub ntawv ntau heev.
Cov kws tshawb fawb hauv Nyij Pooj tau tsim lub pob zeb ntshiab thiab lub teeb rau siv hauv quantum suav hauv kev txav uas tuaj yeem ua rau cov hard drives tshiab. Nws yog ib feem ntawm kev siv zog txuas ntxiv mus siv qhov txawv txav ntawm quantum mechanics los tuav cov ntaub ntawv.
"Tsis zoo li peb cov khoos phis tawj classic uas ua haujlwm ntawm tus lej binary (lossis 'ntsis'), uas yog, 0's thiab 1's, quantum computers siv 'qubits' uas tuaj yeem ua ke ntawm ob lub xeev, " David Bader, tus kws tshaj lij computer science ntawm New Jersey Institute of Technology uas kawm txog quantum nco, hais rau Lifewire hauv kev xam phaj email. "Kev khaws qubits yog qhov nyuaj dua li khaws cia cov khoom qub vim qubits tsis tuaj yeem cloned, yog qhov ua yuam kev, thiab muaj lub neej luv luv ntawm ib feem ntawm ib pliag."
Quantum Memories
Cov kws tshawb fawb tau xav ntev ntev tias cov pob zeb diamond tuaj yeem siv los ua qhov nruab nrab ntawm quantum. Cov qauv crystalline tuaj yeem siv los khaws cov ntaub ntawv raws li qubits yog tias lawv tuaj yeem ua tau ze li tsis muaj nitrogen. Txawm li cas los xij, cov txheej txheem tsim khoom yog qhov nyuaj, thiab txog rau tam sim no, cov pob zeb diamond uas tau tsim muaj tsawg dhau rau lub hom phiaj siv tau.
Adamant Namiki Precision Jewelry Company thiab cov kws tshawb fawb los ntawm Saga University thov kom tau tsim cov txheej txheem tsim khoom tshiab uas tuaj yeem tsim cov pob zeb diamond wafers uas muaj ob nti loj thiab ntshiab txaus rau kev siv tau."A 2-nti pob zeb diamond wafer theoretically enables txaus quantum nco los sau 1 billion Blu-duab tshav discs," lub tuam txhab sau nyob rau hauv cov xov xwm tshaj tawm. "Qhov no yog sib npaug rau tag nrho cov ntaub ntawv xov tooj ntawm tes muab faib hauv ntiaj teb hauv ib hnub."
Bader tau hais tias qhov kev nco txog pob zeb diamond no tso siab rau kev khaws cia qubit raws li kev sib tw nuclear. "Piv txwv li, physicists tau ua pov thawj khaws cia ib tug qubit nyob rau hauv lub spin ntawm ib tug nitrogen atom embedded nyob rau hauv lub pob zeb diamond," nws hais ntxiv.
Kev Tshawb Fawb
Pob zeb diamond tsuas yog ib txoj hauv kev uas quantum computers tuaj yeem khaws cov ntaub ntawv. Cov kws tshawb fawb tab tom nrhiav ob qho kev qhia rau kev tsim quantum nco, ib qho siv kev sib kis ntawm lub teeb thiab lwm qhov siv cov khoom siv lub cev, Bader tau hais.
"Qubits tuaj yeem sawv cev los ntawm lub amplitude thiab theem ntawm lub teeb," Bader ntxiv. "Lub teeb kuj yog siv nyob rau hauv quantum xam lub gradient echo nco qhov twg lub xeev ntawm lub teeb yog mapped rau hauv lub excitation ntawm huab atoms, thiab lub teeb yuav 'un-absorbed' tom qab. Hmoov tsis zoo, txawm li cas los xij, nws tsis tuaj yeem ntsuas qhov amplitude thiab theem yam tsis cuam tshuam nrog lub teeb. Yog li peb tuaj yeem xav txog lub teeb ua ib txoj hauv kev thauj qubits-zoo li lub khoos phis tawj classical."
Txawm tias cov ntaub ntawv txawv dua li pob zeb diamond raug txiav txim siab. Nyuam qhuav pib lub xyoo no, cov kws tshawb fawb tau siv qubit ua los ntawm ib qho ion ntawm lub ntiaj teb tsis tshua muaj, ytterbium, uas tseem siv hauv lasers, thiab embedded no ion nyob rau hauv lub pob tshab crystal ntawm yttrium orthovanadate. Bader tau hais tias "Lub xeev quantum tau raug tswj xyuas siv qhov chaw kho qhov muag thiab microwave," Bader hais.
Quantum nco tuaj yeem muaj teeb meem cuam tshuam uas tsim cov hard drive loj txaus. Bader tau taw qhia tias classical computer storage systems ntawm hom uas muaj nyob rau hauv PCs loj hlob linearly nyob rau hauv cov ntaub ntawv khaws tseg los ntawm classical khoom. Piv txwv li, yog tias koj muab koj ob npaug rau koj lub hard drive ntawm 512GB rau 1TB, koj tau muab ob npaug ntawm cov ntaub ntawv koj khaws tau, nws hais.
Qubits yog "zoo heev" rau khaws cov ntaub ntawv, thiab cov ntaub ntawv uas sawv cev loj hlob exponentially hauv cov qubits. "Piv txwv li, ntxiv ib qho qubit ntxiv rau lub kaw lus ob npaug ntawm cov xeev," Bader hais.
Vasili Perebeinos, tus xibfwb ntawm Lub Xeev University of New York Buffalo uas ua haujlwm ntawm quantum nco, hais rau Lifewire hauv kev xam phaj email tias cov kws tshawb fawb tab tom sim txheeb xyuas cov khoom siv hauv xeev uas tuaj yeem pab tau rau quantum cov ntaub ntawv khaws cia.
Storing qubits yog qhov nyuaj dua li khaws cov khoom qub vim qubits tsis tuaj yeem cloned, ua yuam kev, thiab muaj lub neej luv luv ntawm ib feem ntawm ib pliag.
"Qhov kom zoo dua ntawm lub xeev quantum nco yog nyob rau hauv lub peev xwm los txo qis thiab ntsuas lub quantum network ntaus ntawv Cheebtsam," Perebeinos hais.
Txawm li cas los xij, tsis txhob cia siab tias yuav muaj quantum hard drive hauv koj lub PC sai sai. Bader tau hais tias "nws yuav siv sijhawm ntau xyoo, thiab tej zaum txawm tias kaum xyoo, los tsim kom muaj lub computer loj txaus nrog cov qubits txaus los daws cov ntawv thov hauv ntiaj teb tiag."
