Justin Drake Puts Quantum "Q-Day" Odds at 50% by 2032

Ethereum researcher Justin Drake dropped fresh numbers on the quantum threat this morning, posting on X he thinks there's now a coin-flip chance of a quantum computer cracking live cryptography by 2032.

What's the Scoop?

• The Breakthrough: On March 31st, Google Quantum AI revealed a 10x speedup for Shor's algorithm against elliptic curve cryptography, demonstrated on secp256k1 (the curve securing Bitcoin and Ethereum signatures).
• Keeping the Secret: After what Google described as engagement with the U.S. government, the team locked its key optimizations behind a zero-knowledge proof, which Drake (a co-author on the paper) framed as a first-of-its-kind act of academic censorship.
• Streisand Effect: That secrecy didn't hold, though. As Drake noted, French quantum researcher André Schrottenloher just independently rediscovered the main optimization and posted it to arXiv, while Google's Craig Gidney admitted in a blog post that he'd sat on the same trick for a year under pressure to keep quiet.
• 10K Qubits: A stealth startup called Oratomic now claims that just 10,000 physical qubits could run Shor on secp256k1 using neutral-atom hardware, a figure Drake called "mind-bogglingly low." After a couple hundred hours researching the tech, Drake said it's real, noting that even Google has opened a neutral-atom lab.
• The Odds: With all this context, Drake now puts q-day (the moment a quantum computer breaks production crypto) at 50% by 2032 and 10% by 2030. The window for migrating to quantum-resistant, hash-based cryptography is getting that much more unforgiving, it seems.
