NIST Advances Nine Candidates to the Third Round of Additional Post-Quantum Digital Signatures

The U.S. National Institute of Standards and Technology (NIST) has advanced nine digital signature algorithms to the third round of its Additional Post-Quantum Cryptography standardization process. These candidates offer diverse options including compact isogeny-based SQIsign and efficient lattice-based HAWK schemes. The selection enhances resilience against quantum threats for applications from IoT devices to software signing and TLS certificates.

Haiqu Launches Agentic Quantum Operating System to Accelerate Enterprise Quantum R&D

Haiqu has introduced its Agentic Quantum Operating System (HaiquOS), a full-stack quantum intelligence platform that combines agentic AI with proprietary middleware. The solution helps R&D teams identify suitable problems, design experiments, and interpret results from today’s noisy quantum hardware with minimal custom engineering. Internal benchmarks show dramatic efficiency gains, including a molecular dynamics simulation reduced from over nine hours and $30,000 to roughly 30 seconds and $25. HaiquOS is already gaining interest from organizations including Capgemini and Deloitte.

Quantum Computing Digest — 2022

In 2022, quantum computing transitioned from speculative hype to pressing operational risks, forcing organizations to address immediate challenges in security, hardware, software, policy, fragile supply chains, and workforce shortages. Post-quantum cryptography advanced from theory to active planning and procurement, as delays now posed tangible security and compliance threats, while overhyped hybrid quantum-classical systems faced increased skepticism. Ultimately, the year highlighted that quantum adoption will hinge far more on mastering today’s engineering, infrastructure, and execution risks than on awaiting major theoretical breakthroughs.
