Quantum Computing Expert Answers All Your Crypto Questions | Presto Research

Presto Research published a Q&A with Professor Isaac Kim, Assistant Professor of Computer Science at UC Davis, explaining the intersection of quantum computing and cryptocurrency for crypto readers. The article states that Shor's algorithm could one day break elliptic curve cryptography, which secures most wallets, recovering private keys from exposed public keys. It also says that current quantum computers are not yet powerful enough, since breaking ECC would require thousands of nearly flawless qubits, while existing gates fail roughly one in a thousand times. Post-quantum cryptography is presented as a defense, though the article notes it brings larger keys and slower signatures.
