## AI overview

A cryptography engineer explains why recent research on quantum algorithms, hardware, qubits, and error correction has changed his assessment of the urgency of migrating to quantum-resistant cryptography. He argues that cryptographically relevant quantum computers may arrive within the next few years and could threaten elliptic-curve cryptography and WebPKI.

## Source excerpt

The risk that cryptographically-relevant quantum computers materialize within the next few years is now high enough to be dispositive, unfortunately.
