Ithimba labacwaningi abavela kumalabhorethri amaningana ase-Europe kanye nezinkampani ezingochwepheshe be-quantum computing libale imingcele yekhompuyutha ye-quantum edingekayo ukuqagela ukhiye oyimfihlo ovela kukhiye womphakathi osuselwa ku-256-bit elliptic curve-based (ECDSA) osetshenziswa ku-cryptocurrency ye-Bitcoin. Ukubala kubonise ukuthi ukugebenga i-Bitcoin usebenzisa amakhompyutha we-quantum akulona iqiniso okungenani iminyaka eyi-10 ezayo.
Ikakhulukazi, ama-qubits aphathekayo angu-256 Γ 317 kuzodingeka ukuze ukhethe ukhiye we-106-bit ECDSA phakathi nehora. Okhiye basesidlangalaleni ku-Bitcoin bangahlaselwa kuphela phakathi kwemizuzu eyi-10-60 yokuqala ukuthengiselana, kodwa ngisho noma isikhathi esiningi singase sisetshenziswe ekugebheni, ukuhleleka kwamandla ekhompiyutha ye-quantum kusalokhu kufana nokukhula kwesikhathi. Isibonelo, ukusampula kosuku kudinga ama-qubits abonakalayo angu-13 Γ 106, futhi izinsuku ezingu-7 zidinga ama-qubits abonakalayo angu-5 Γ 106. Uma kuqhathaniswa, ikhompuyutha enamandla kakhulu ye-quantum edaliwe manje inama-qubits angama-127.
