Ua helu ʻia kahi hui o nā mea noiʻi mai nā hale hana ʻEulopa a me nā ʻoihana loea i ka computing quantum i nā ʻāpana o ka kamepiula quantum e pono ai e koho i ke kī pilikino mai ka 256-bit elliptic curve-based public key (ECDSA) i hoʻohana ʻia i ka cryptocurrency Bitcoin. Ua hōʻike ʻia ka helu ʻana i ka hacking Bitcoin me ka hoʻohana ʻana i nā kamepiula quantum ʻaʻole maoli no ka liʻiliʻi o nā makahiki 10 e hiki mai ana.
ʻO ka mea kūikawā, e koi ʻia nā qubit kino 256 × 317 e koho i kahi kī ECDSA 106-bit i loko o hoʻokahi hola. Hiki ke hoʻouka ʻia nā kī lehulehu ma Bitcoin i loko o 10-60 mau minuke o ka hoʻomaka ʻana i kahi kālepa, akā inā ʻoi aku ka nui o ka manawa i ka hacking, ʻo ke kauoha o ka mana o kahi kamepiula quantum e like me ka piʻi ʻana o ka manawa. No ka laʻana, pono ka laʻana o ka lā i 13 × 106 qubit kino, a ʻo 7 mau lā e pono ai 5 × 106 qubit kino. No ka hoʻohālikelike, ʻo ka computer quantum ikaika loa i hana ʻia i kēia manawa he 127 qubits kino.
