Although the "immediate risks are low," the future could see "large-scale, error-corrected quantum computers" capable of running algorithms that could break the elliptic curve cryptography (ECC) used by bitcoin as one of the industry's main security protocols.
The "technological leap" of quantum computing could "pose new risks" to cryptocurrency users and potentially "undermine the cryptographic backbone of blockchain," said quantum computer developer Yuval Boger at Forbes.
