Ib pab neeg tshawb fawb los ntawm cov tsev kawm qib siab hauv tebchaws Australia thiab Tebchaws Meskas, ua haujlwm koom tes nrog quantum thev naus laus zis lub tuam txhab BTQ, tsis ntev los no tau tshaj tawm cov kev tshawb fawb tawm tswv yim tshiab ua pov thawj ntawm kev ua haujlwm (PoW) cov tswv yim rau blockchain kev pom zoo uas tso siab rau quantum xam cov tswv yim kom muaj kev pom zoo.
Peb daim ntawv tshiab ntawm kev siv NISQ-era quantum sampling teeb meem hauv cov ntaub ntawv pov thawj-ntawm-ua haujlwm blockchain pom zoo algorithms. Hauv kev koom tes nrog @BTQ_Tech.https://t.co/MKAB2czqSk

Dubbed "Kev pom zoo ntawm kev ua haujlwm los ntawm quantum sampling," cov ntawv tshawb fawb ua ntej qhia txog cov txheej txheem uas cov kws sau ntawv thov "muab kev nrawm nrawm thiab txuag hluav taws xob cuam tshuam rau kev suav los ntawm cov khoom siv qub."
Raws li cov kws tshawb fawb, cov algorithms tam sim no rau kev daws teeb meem kev pom zoo ntawm PoW yog qeeb thiab yuav tsum muaj qhov tseem ceeb ntawm kev suav cov peev txheej los ua:
"Thaum cov txheej txheem PoW classical xws li Bitcoin's tsis muaj lub zog tsis muaj zog, peb cov boson sampling-based PoW scheme muab lub zog ntau dua lwm txoj hauv kev thaum siv quantum hardware."
Raws li daim ntawv, quantum kom zoo dua los ntawm cov tswv yim no tseem yuav ua rau muaj kev nyuaj ntawm kev tsuas, yog li ua rau nws muaj peev xwm "tswj lub sijhawm thaiv cov mining" raws li tus naj npawb ntawm cov miners nce, ntxiv dag zog ntxiv kev koom tes ntawm "quantum miners."
Cov txheej txheem piv txwv cov kws tshawb fawb xa mus, boson sampling, tsis yog ib qho tshiab, tab sis nws daim ntawv thov rau blockchain thev naus laus zis zoo li tshiab. Boson sampling tau pom cov lus cog tseg hauv ntau daim ntawv thov kev suav quantum. Tseem, raws li cov kev daws teeb meem tsis yog thoob ntiaj teb quantum (nws yuav tsum tau siv rau hauv lub kaw lus tsim rau ib txoj haujlwm tshwj xeeb), nws lub peev xwm tau txwv rau qee qhov kev xaiv, xws li chemistry.

Txawm li cas los xij, raws li cov kws tshawb fawb, nws yuav yog qhov kev daws teeb meem zoo tshaj plaws rau yav tom ntej-pov thawj blockchain daim ntawv thov thiab, muaj peev xwm, txo qis ib puag ncig kev cuam tshuam ntawm mining ntawm Bitcoin blockchain thiab cov saw zoo sib xws.
Ib cag ntawm quantum kom zoo dua, quantum hardware kuj muaj ib ceg ntawm cov tsev kawm ntawv qub computers vim qhov xwm txheej ntawm blockchain mining ua haujlwm li cas.
Ib qho txiaj ntsig tam sim no ntawm classical supercomputers tshaj lawv cov kwv tij quantum tshiab yog lub peev xwm "precompute" thaum tuav tib chav kawm ntawm qhov teeb meem tsis tu ncua. Tab sis, thaum nws los txog rau blockchain, xws li precompute yog qhov tseem ceeb nkim.
Mining yog, raws li cov kws tshawb fawb tau hais, qhov teeb meem uas "tsis muaj kev vam meej." Txawm hais tias muaj pes tsawg zaus blockchain puzzle yog daws los muab cov ntaub ntawv pov thawj-ntawm-ua haujlwm, lub computer thiab algorithms ua cov kev cov nyom tsis tau zoo dua los daws qhov teeb meem.
Qhov no txhais tau hais tias quantum computers, txawm hais tias muaj kev nyuaj siab los tsim thiab kim los tsim thiab tswj, thaum kawg yuav muaj peev xwm ua kom muaj kev pom zoo zoo dua li lub xeev-of-the-art classical systems.
