What's covered

TSMC Margin Squeeze Signal

TSMC posted its sixth consecutive quarter of record profit last week, and its stock fell four and a half percent. That's the story.

Quantum Hardware Readiness Assessment

Now to the longer-duration story in this briefing. A cross-platform assessment published in Science, co-authored by researchers from MIT, the University of Chicago, and Stanford, benchmarks six major quantum hardware platforms on a nine-point readiness scale.

China Quantum Ecosystem Acceleration

China's quantum posture is shifting from moonshot announcements toward ecosystem coordination. Logical Qubit's COO described twenty-twenty-six as year one of a coordinated Chinese quantum ecosystem, with hardware, software, and component suppliers now working in structured collaboration.
