Quantum computers should be powerful enough to crack Bitcoin’s security features—by instantly solving the mining mechanism or guessing wallet passwords by brute force—a few years after 2030, according to the CEO of a company working in partnership with Nvidia on its quantum computing efforts.
Quantum technology is not yet good enough to pose a threat to cryptocurrency, but it is getting there, Théau Peronnin, the CEO of Alice & Bob, told Fortune at Web Summit in Lisbon. (The company’s name is based on a joke about cryptography texts, which often state problems by using two fictional characters, Alice and Bob, who need to communicate with each other in secret.)
