A Cryptography Engineer's Perspective on Quantum Computing Timelines (words.filippo.io)

A cryptography engineer argues that timelines for breaking widely used elliptic-curve cryptography with quantum computers have accelerated, citing recent papers from Google and Oratomic that reduce required qubits and could enable practical man-in-the-middle risks. The author says the risk window is now too short to rely on “hybrid” approaches or waiting, and recommends fast migration to post-quantum signatures and key exchange—while flagging that some non-PQ hardware trust anchors (like current TEEs) may not be quantum-safe. They conclude that organizations should start shipping quantum-resistant cryptography now, even if exact dates remain uncertain.
