The findings suggest attackers could one day steal bitcoin mid-transaction, challenging assumptions that the threat is decades away.

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently written whitepapers have concluded.

Google researchers have shown that breaking the encryption of cryptocurrencies such as Bitcoin and Ethereum requires 20x fewer qubits.

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.
