Round Type Taxonomy Not Populated: No entries exist for Seed, Pre-Seed, Grant, Series A or later, Venture Round, Corporate Round, Convertible Note, or Other Equity. No funding dates, round labels, or currency-formatted amounts are present in the ViQium Technologies Co., Ltd. Enterprise Knowledge Graph provided as the sole permitted data source.

Disclosed Non-Funding Capital/Asset Basis (source-verifiable): The knowledge base describes an internally developed, self-established production capability rather than external capital events. Verbatim-scope facts include:

• An independently established complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing.
• In-house fabrication platforms for NV centers in diamond via high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) methods.
• A systematic patent strategy implemented with a forward-looking approach to safeguard technological independence, spanning black phosphorus and emerging phosphorus-based materials, diamond quantum materials and devices, precision processing and functionalization of superhard materials, and large-scale phosphide single crystal growth.
• Founding team research track record exceeding eight years in advanced quantum materials, including NV center quantum diamonds and black phosphorus.

These items are intellectual property, R&D, and production capabilities. They are not funding events and are not presented as such.
