Fujitsu thiab Riken lub koom haum tshawb fawb, Japanese tech multinationals cia siab tias yuav koom ua ke tso lub peev xwm Bitcoin-beating quantum computer rau cov tuam txhab hauv 2023.
Lub khoos phis tawj, muaj zog ntau dua Frontier, lub ntiaj teb lub khoos phis tawj nrawm tshaj plaws tsim los ntawm Hewlett-Packard, xav tias yuav siv thawj zaug rau kev kwv yees nyiaj txiag thiab tsim cov tshuaj tshiab.
Fujitsu lub khoos phis tawj tshiab yuav siv cov ntaub ntawv hu ua superconductor uas pom tsis muaj hluav taws xob tsis zoo thaum txias kom ze rau qhov kub uas hu ua "zero kiag li."
"Quantum suav muaj peev xwm hloov lub ntiaj teb ntawm qib loj. Koj tuaj yeem daws cov teeb meem hauv molecular dynamics, nyiaj txiag, tshuaj, "said Fujitsu CEO Vivek Mahajan hauv lub Kaum Hlis 14, 2022. kev sib tham nrog CNBC
Raws li Mahajan, quantum computers muaj peev xwm daws tau qhov teeb meem kev ua lej zoo li Shor's algorithm lossis qhov teeb meem hu ua tus neeg muag khoom mus ncig. Nws tuaj yeem daws tau lwm yam teeb meem suav tias nyuaj heev rau txawm tias supercomputers. Shor's algorithm siv quantum thev naus laus zis los twv qhov tseem ceeb ntawm kev siv tshuab. Thaum cov teeb meem kev mus ncig ua lag luam sim nrhiav txoj kev luv tshaj plaws uas tuaj yeem coj mus xyuas txhua lub nroog txuas nrog txoj kev loj hauv zos, thiab tom qab ntawd rov qab mus rau qhov chaw pib.
Thaum cov tuam txhab xws li Google tau ua qhov tseem ceeb hauv kev tsim lawv tus kheej lub computer supercomputer, nws tsuas pom kev lag luam muaj peev xwm ntawm nws lub tshuab hauv 2029, uas tuaj yeem ua rau Fujitsu pib pib.
Fujitsu lub koos pij tawj muaj 64 "qubits," lub ntsiab lus ntawm cov ntaub ntawv hauv quantum computer, piv rau Google's 53.
Fujitsu hais txog Bitcoin quantum hem
P2P pauv LocalBitcoins, nrog rau a 2022 cov ntawv kawm los ntawm Sussex University tau ceeb toom tias quantum computers tuaj yeem tawg SHA256 algorithm siv hauv Bitcoin network.
Miners hauv ib Cov ntaub ntawv pov thawj ua haujlwm blockchain system zoo li Bitcoin sib tw los nrhiav cov lej daws teeb meem rau SHA256 algorithm uas ntaus lub hom phiaj network hu ua qhov nyuaj. Miners ua qhov hu ua lub ntsej muag kev ua haujlwm ntawm lub header ntawm Bitcoin kev lag luam thaiv thiab tus lej random. Siv SHA256 algorithm, kom tau txais cov lej daws teeb meem uas ua raws li qee yam qauv. Cov miner feem ntau tsuas yog kwv yees qhov kev daws teeb meem tom qab ua quadrillions ntawm "hashing" ua haujlwm ib ob. Rau mining Bitcoin, lub khoos phis tawj ntawm kev xaiv rau cov txheej txheem hashing yog Daim Ntawv Thov-Specific Integrated Circuit (ASIC). Qhov kev ua lej nyuaj ntawm kev nrhiav cov kev daws teeb meem pab tiv thaiv Bitcoin network, thiab tsis muaj nws, lub network kev ruaj ntseg, uas mus txog rau tam sim no tau raug mos mos, tuaj yeem ua txhaum cai.
Tab sis quantum computers tseem tawm tsam nrog kev ua haujlwm ntev, thiab kev tshawb fawb tsis ntev los no rau tom qab quantum cryptography los ntawm cov tuam txhab xws li IBM thiab Thale tau maj mam pleev xim rau cov duab pom tseeb ntawm lub neej tom ntej tom qab quantum. Lub Tebchaws Asmeskas Lub Tsev Haujlwm ntawm Cov Qauv thiab Tshuab yog tus thawj coj hauv kev tshawb nrhiav txog qhov muaj peev xwm quantum-resistant cryptographic algorithms.
Cov tswv yim los tawm tsam quantum thev naus laus zis tau thov txij li tsawg kawg 2019 thaum Google thawj zaug luam tawm cov txiaj ntsig ntawm nws lub tshuab.
Ethereum Co-founder Vitalik Buterin thaum lub sijhawm ciali tsis muaj kev ntxhov siab ntawm lub peev xwm hem rau crypto. Nws tau xav tias zoo ib yam li yuav ua li cas lub foob pob hluav taws xob tau tsim, siv lub zog nuclear hauv kev siv niaj hnub zoo li tsis yooj yim. Quantum suav lub zog yuav tsum tau ua tib zoo siv kom nws thiaj li hloov tau. Nws kuj tau pom tias lub zej zog cryptocurrency yuav tsim cov algorithms tshiab.
"Tab sis rau txhua qhov cryptographic algorithm uas quantum computers tuaj yeem tawg, peb paub tias peb muaj qhov hloov pauv uas quantum computers tsis tuaj yeem tawg."
Hauv 2019, tus kws tshawb fawb ntawm Ethereum lub hauv paus tau nthuav tawm cov tswv yim quantum resistance uas tuaj yeem siv rau Ethereum blockchain. Lwm tus tab tom tsim cryptocurrencies tshiab thiab blockchains zoo li cov Quantum Resistance Ledger.
Cov kev daws teeb meem uas twb muaj lawm suav nrog kev siv zog los ntawm IOTA developers los qhia thiaj li hu qhia acyclic graph technology, thiab JPMorgan's quantum key-distribution technology.
