A group of researchers from several European laboratories and companies specializing in quantum calculations, calculated The parameters of the quantum computer required for Selecting a closed key on a 256-bit open key based on elliptic curves ( ECDSA ) used in cryptocurrency Bitcoin. The calculation showed that in the foreseeable future, Bitcoin hacking with quantum computers in the next 10 years is not realistic.
In particular, on the selection of the selection of the 256-bit ECDSA key for an hour, it will take 317 × 10 6 physical qubs, during the day – 13 × 10 6 physical cubes, 7 days – 5 × 10 6 physical cubes. For comparison, the most powerful of the currently created quantum computers has 127 physical quicts.
