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 ...

Ethereum co-founder Vitalik Buterin has sent a harsh warning about the dangers posed by quantum computing to the crypto economy. "Seemingly," there is a 20% chance of quantum computers breaking modern ...

Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of it as being locked in a vault so strong that even all the world’s ...

A research paper from Caltech and quantum startup Oratomic found that the cryptography protecting bitcoin and ether wallets could be broken with as few as 10,000 physical qubits, far below earlier ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...
