The post-quantum debate has become “my lattice is better than your hash.” “We don’t have proofs of security for any of this stuff.” @YuviLightman with @ilblackdragon on how AI could help harden cryptography, and why that work needs to happen in public.

India, we’re heading your way. Join @quantusnetwork and @nearprotocol for some peer-to-peer connections. Be fast, space is running out.

Last week in quantum The Quantum Alliance launched to define quantum readiness Ten contributors from nine organizations, including Quantus CEO @YuviLightman, launched the Quantum Alliance, an open standards body for post-quantum readiness in blockchain. It will publish a public definition of quantum readiness, open test criteria, and reference designs for migration. Starknet opened a vote on researching an exit from Ethereum @Starknet opened a non-binding poll on whether to research becoming an independent post-quantum L1. Starknet targets full quantum resistance by 2027, and its bridge and data availability currently move on Ethereum’s schedule. A Yes vote starts research only. The poll closes October 22. AI designed more efficient quantum circuits @AnthropicAI, working with researchers from Harvard and @QueraComputing, had Claude design circuits for eight quantum computing tasks. Each design beat the best previously published one. One design for elliptic-curve point addition, the core step in quantum attacks on ECDSA, uses 17 times fewer gates than the smallest previous design. It reduces what a quantum algorithm needs to run. Google made a key quantum ingredient far more reliable Quantum computers need special “magic states” to run the full range of algorithms, including the kind that could one day break today’s encryption. They’re hard to make. Earlier estimates said producing them could take up to 95% of a machine’s qubits. In a paper published in Science, Google showed a new method on its Willow chip that cut errors in these states about 40-fold. Google says it still has to work at larger scale. Singapore set quantum-safe deadlines Singapore’s Cyber Security Agency asked critical infrastructure operators to submit migration plans by March 2027 and finish migrating by the end of 2031. Other exposed organizations are encouraged to finish by 2035. A grant for quantum-safe pilots opens November 1. Germany set its own post-quantum timeline Germany’s interior ministry, digital ministry, and federal security agency BSI published a national guideline implementing the EU’s post-quantum roadmap. High-risk systems should be quantum-safe by the end of 2030, with the rest largely migrated by 2035. It also calls for crypto-agility, so cryptography can be swapped quickly as threats change. Governments are setting dates. Researchers are making quantum computers easier to build and their algorithms cheaper to run.
