Qubit yog ib chav tsev ntawm cov ntaub ntawv quantum; Peb yuav tsum muaj pes tsawg qubits los rhuav tshem cov txheej txheem crypto txiaj tshaj plaws hauv xyoo 2023?
txheem
Ib pawg ntawm Suav cryptographers tau tshaj tawm cov lus qhia txog yuav ua li cas quantum computers uas twb muaj lawm tuaj yeem rhuav tshem Rivest-Shamir-Addleman (RSA), ib qho tseem ceeb rau pej xeem cryptosystem siv los ntawm blockchains. Lub caij no, qee tus kws tshaj lij cryptocurrency tsis ntseeg txog qhov kev tsim no.
372 lub cev qubits yog txaus los rhuav RSA-2048
Thaum lub Kaum Ob Hlis Ntuj xyoo 2022, ib pawg ntawm cov kws tshawb fawb los ntawm Zhengzhou, Hangzhou thiab Beijing, coj los ntawm Bao Yan thiab Ziqi Tan, tau sib koom ib qho kev qhia hu ua Factoring integers nrog sublinear peev txheej ntawm superconducting quantum processor. Nws piav qhia txog kev siv peev txheej ntau dua ntawm kev nyuaj RSA-2048 cryptography dua li yav dhau los.

Yav dhau los, nws tau txiav txim siab tias tus neeg muaj peev xwm tawm tsam yuav xav tau ntau lab lub cev qubits los rhuav tshem kev ncaj ncees ntawm cov txheej txheem hais saum toj no, uas yog deb dhau qhov peev xwm kho vajtse tam sim no ntawm quantum computers.
Hloov chaw, lub tswv yim algorithm tuaj yeem cuam tshuam cov teeb meem los ntawm kev tsim cov lej mus txog 48 cov khoom nrog 10 superconducting qubits, qhov loj tshaj qhov sib npaug ntawm cov khoom siv quantum.
Raws li qhov tshwm sim, tus neeg muaj peev xwm tawm tsam xav tau 372 lub cev qubits los rhuav tshem RSA-2048 lub tswv yim. Txhawm rau muab cov ntsiab lus, QuEra Computing ntaus ntawv los ntawm physicists ntawm Harvard thiab MIT muaj 256 qubits, thaum IBM's Condor tau teem kom dhau 1,000-qubit cim hauv 2023.
Tsis muaj kev txhawj xeeb, cov kws tshaj lij hais
Txawm li cas los xij, feem ntau ntawm cov kws tshaj lij tau pom kev tsis ntseeg txog cov ntaub ntawv tshiab tshaj plaws los ntawm cov kws tshawb fawb Suav. Piv txwv li, Ethereum (ETH) qub tub rog @dystopiabreaker (Suzuha) thov tias qhov kev tshawb fawb no yog los ntawm ib daim ntawv thuam dav dav:
lawv txoj kev cia siab rau Schnorr's "destroyes RSA" ntawv los ntawm ob peb xyoos dhau los, uas tau pom tias tsis ua haujlwm zoo nrog cov qauv loj dua. tsis paub meej tias lawv tau kov yeej qhov kev txwv no lossis tsis tau. Kuv tsis ntseeg, ib yam li nrog daim ntawv schnorr, qhia koj txoj haujlwm
Lwm tus kws tshaj lij tau hais ntxiv tias thaum qhov kev tawm tsam no dhau los ua tiag tiag, pawg blockchain yuav yooj yim hloov mus rau kev ruaj ntseg cryptographic ntau dua.
Tus kws paub txog computer tseem ceeb Bruce Schneier, tus kws qhia ntawv ntawm Harvard's Kennedy School, hais rau rau cov xov xwm uas nws tsis xav tias "qhov no yuav ua rau RSA tawg."
