Ib pab pawg ntawm cov kws tshawb fawb los ntawm ntau lub chaw soj nstuam European thiab cov tuam txhab tshwj xeeb hauv quantum suav tau suav cov tsis muaj lub computer quantum xav tau los twv tus yuam sij ntiag tug los ntawm 256-ntsis elliptic nkhaus-raws li pej xeem key (ECDSA) siv hauv Bitcoin cryptocurrency. Kev xam pom tau hais tias kev nyiag Bitcoin siv quantum computers tsis muaj tseeb rau tsawg kawg 10 xyoo tom ntej.
Tshwj xeeb, 256 Γ 317 lub cev qubits yuav tsum xaiv 106-ntsis ECDSA tus yuam sij hauv ib teev. Cov yuam sij pej xeem hauv Bitcoin tsuas tuaj yeem tawm tsam tsis pub dhau 10-60 feeb ntawm kev pib ua lag luam, tab sis txawm tias muaj sijhawm ntau tuaj yeem siv rau kev nyiag khoom, qhov kev txiav txim ntawm lub zog ntawm lub computer quantum tseem zoo ib yam li lub sijhawm nce. Piv txwv li, ib hnub sampling yuav tsum 13 Γ 106 lub cev qubits, thiab 7 hnub xav tau 5 Γ 106 lub cev qubits. Rau kev sib piv, lub zog tshaj plaws quantum computer tam sim no tsim muaj 127 lub cev qubits.
