Diamond & Quantum Weekly | Jun 22–28, 2026
A proposed EPC contract and a project signing created traceable industrial leads, but neither established commissioning, product validation, or customer adoption.
Weekly signal
Contracts and project signings are starts, not industrialization outcomes.
Jiuzhou Yigui disclosed a proposed RMB107.38 million EPC contract with an investee company for phase one of a diamond chip-substrate project. A regulatory disclosure is a stronger anchor than media repetition, but the proposed contract did not establish commissioning, successful substrate production, or customer supply.
A RMB1.5 billion Zhongke Fenyan diamond-semiconductor project appeared in provincial media as a signed project. It remained a watch item pending filing, construction, equipment delivery, process definition, and customer validation.
Quantum-policy reporting emphasized US targets, post-quantum migration, and infrastructure. Debate around Microsoft’s Majorana route reinforced the need to separate a company roadmap from independent technical validation. These topics were relevant to the broader quantum environment but did not directly establish a diamond benefit.
The period’s rule was simple: follow every project through contract, filing, construction, equipment, product, qualification, and revenue.
Evidence limits and uncertainties
- Project values and scope describe proposed or signed activity, not completed investment or product output.
