Editor's Note

This issue’s highlights focus on policy promotion and industry collaboration. The White House Quantum Summit and the AWS-QuEra partnership mark a clarified timeline (2028) for fault-tolerant quantum computing, though overpromising should be guarded against. Diraq’s eight-qubit CMOS demonstration is a significant milestone for silicon-based quantum computing but remains far from practical use. In financing, large investments in quantum sensing and semiconductor inspection reflect industry confidence in near-term applications. Academically, the substantial increase in magnon coherence time and the discovery of the fractional Fermi sea provide new platforms for quantum information processing. Overall, quantum computing is accelerating its transition from fundamental research to engineering, but true quantum advantage still requires years of validation.
