MIT Tech Review hais tias Quantum computers yog xyoo deb ntawm cracking crypto 

• Quantum computers yog tam sim no nyob ze rau cracking crypto
• RSA-Cryptography siv algorithms, codes thiab cov yuam sij kom ruaj ntseg encrypt cov ntaub ntawv ntiag tug
• Sarma tam sim no ua tus thawj coj ntawm University of Maryland's condensed matter theory center 

Consolidated teeb meem hypothesis physicist thiab quantum cov ntaub ntawv tswv Sankar Das Sarma tau sib cav nyob rau hauv MIT Technology Review tias quantum PCs nyob deb heev los ntawm rhuav RSA-raws li cryptography.

RSA-Cryptography siv cov kev suav, cov lej thiab cov yuam sij kom muaj kev nyab xeeb ntawm cov ntaub ntawv ntiag tug yam tsis muaj kev cuam tshuam los ntawm cov neeg sab nraud lossis cov neeg ua yeeb yam tsis zoo xws li programmers. Ib qho piv txwv ntawm cov txheej txheem hauv crypto yog kev tsim khoom ntawm lwm lub hnab nyiaj uas tsim ib qho chaw pej xeem thiab tus yuam sij ntiag tug.

Quantum kev ruaj ntseg tau pom tias yog qhov teeb meem loj hauv blockchain 

Quantum kev ruaj ntseg yog saib raws li qhov teeb meem tseem ceeb nyob rau hauv lub blockchain thiab crypto cheeb tsam thiab nws yog feem ntau lees txais tias muaj zog quantum PCs yuav muaj ib hnub kev vam meej mus rau lub ntsiab lus ntawm hacking tam sim no cryptography. 

Qhov ntawd tuaj yeem nqa txog kev nyiag khoom ntawm ntau lab nyiaj daus las tsim nyog ntawm cov peev txheej siab lossis nqa blockchain thev naus laus zis mus rau qhov nres nres. Muaj ntau yam kev cog lus los tsim quantum-confirmation cryptography thiab blockchains.

Sarma tam sim no sau ua tus saib xyuas ntawm University of Maryland qhov chaw sib sau ua ke qhov kev xav thiab piav qhia nws cov kev xav ua ntej lub lim tiam no los ntawm Kev Tshawb Fawb Technology.

Tus kws kho mob tau hais tias nws chim siab los ntawm ib feem ntawm quantum xam qhov kev tshaj tawm kuv pom niaj hnub no thiab txaus siab rau qhov xwm txheej tam sim no ntawm kev tsim kho tshiab raws li kev ua tiav loj loj. " Txawm li cas los xij, qhov no yuav siv sij hawm peb tsis nyob ze rau qhov muaj quantum PC uas tuaj yeem saib xyuas qhov teeb meem uas leej twg xav txog ntau zaus.

Nws zoo li kev sim ua kom tam sim no lub xov tooj zoo tshaj plaws siv lub tshuab nqus tsev vacuum los ntawm nruab nrab xyoo 1900s.

Tus kws kho mob tshwj xeeb tau hais tias qhov zoo tshaj plaws hauv qhov uas quantum PC tuaj yeem daws qhov teeb meem nyuaj ntawm kev nrhiav cov kev hloov pauv loj ntawm cov lej loj heev sai dua li txhua txoj kev npaj ib txwm muaj, txawm li cas los xij kev rhuav tshem cryptography yog tam sim no dhau los ntawm kev tuav ntawm lub zog ua tam sim no.

Xx labs tau pib lub blockchain ib yam nkaus

Sarma tseem ceeb qubits uas yog quantum khoom xws li electron lossis photon uas txhawb nqa lub peev xwm ntawm quantum PC:

Cov tsim ntau tshaj plaws quantum PCs niaj hnub no muaj ntau lub cev qubits decohering. Tsim lub quantum PC uas tuaj yeem txiav txim siab RSA cov lej tawm ntawm cov khoom zoo li no yuav xav tau ntau tus lej hauv qhov xwm txheej uas tsis yog ntau lab qubits. Tsuas yog ib tug loj tus naj npawb ntawm cov no yuav raug siv rau kev xam - liam qubits raug cai; tus so yuav xav tau rau kev kho tsis raug cai, ua rau decoherence, nws hais ntxiv.

Thaum Sarma tsis kam mloog cov lus ceeb toom cryptographic, nws pom tias quantum PC tiag tiag yuav muaj cov ntawv thov tsis txaus ntseeg hnub no. Qhov no yog ib qho zoo sib xws uas tsis muaj leej twg tuaj yeem cia siab tias thawj cov khoom siv hluav taws xob ua rau xyoo 1947 yuav ua rau cov chaw ua haujlwm thiab cov xov tooj ntawm tes ntawm lub sijhawm no.

Txawm hais tias muaj kev phom sij yog ob peb txoj hauv kev tawm, ntau lub tuam txhab tam sim no tau tsim kev sim los txhawb kev ruaj ntseg quantum. 

Cointelegraph tau tshaj tawm lub hli tas los hais tias Tebchaws Asmeskas kev lag luam nyiaj txiag dab JP Morgan tau tshaj tawm cov kev tshawb fawb txog kev nthuav tawm quantum tseem ceeb tshaj tawm blockchain network uas yog impervious rau quantum processing assaults.

Xx labs kuj tau xa tawm ntawm blockchain nws thov yog quantum-kev nyab xeeb thiab kev nyab xeeb nyob hauv ib puag ncig blockchain.
