Gulu la ofufuza ochokera m'ma laboratories angapo aku Europe ndi makampani okhazikika pakompyuta ya quantum awerengera magawo akompyuta yofunikira kuti aganizire chinsinsi chachinsinsi kuchokera pa kiyi ya 256-bit elliptic curve-based public key (ECDSA) yomwe imagwiritsidwa ntchito mu cryptocurrency ya Bitcoin. Kuwerengerako kunawonetsa kuti kubera Bitcoin pogwiritsa ntchito makompyuta a quantum sizowona kwa zaka 10 zikubwerazi.
Makamaka, 256 Γ 317 qubits zakuthupi zidzafunika kusankha 106-bit ECDSA kiyi mkati mwa ola limodzi. Makiyi apagulu ku Bitcoin amatha kumenyedwa mkati mwa mphindi 10-60 poyambitsa kugulitsa, koma ngakhale nthawi yochulukirapo ingagwiritsidwe ntchito pakubera, dongosolo lamphamvu la makompyuta a quantum limakhalabe lofanana ndi kuchuluka kwa nthawi. Mwachitsanzo, kuyesa kwa tsiku kumafunikira 13 Γ 106 zolimbitsa thupi, ndipo masiku 7 amafunikira 5 Γ 106 qubits zakuthupi. Poyerekeza, kompyuta yamphamvu kwambiri ya quantum yomwe idapangidwa pano ili ndi ma qubits 127.
