Chikwata chevaongorori kubva kuEurope marabhoritari akati wandei uye makambani anoshanda nequantum computing akaverenga maparamendi ekombuta yehuwandu inodiwa kufungidzira kiyi yakavanzika kubva ku256-bit elliptic curve-based public key (ECDSA) inoshandiswa muBitcoin cryptocurrency. Iko kuverenga kwakaratidza kuti kubira Bitcoin uchishandisa quantum makomputa hakusi kwechokwadi kweanenge makore gumi anotevera.
Kunyanya, 256 Γ 317 qubits yemuviri ichadikanwa kusarudza 106-bit ECDSA kiyi mukati meawa. Makiyi eruzhinji muBitcoin anogona kungorwiswa mukati me10-60 maminetsi ekutanga kutengeserana, asi kunyangwe kana nguva yakawanda ichigona kupedzerwa pakubira, kurongeka kwesimba rekombuta yequantum kunoramba kwakafanana nekuwedzera nguva. Semuenzaniso, sampling yezuva inoda 13 Γ 106 qubits yemuviri, uye mazuva manomwe anoda 7 Γ 5 qubits yemuviri. Kuenzanisa, iyo yakanyanya simba quantum komputa yakasikwa ine 106 yemuviri qubits.
