ViQium Technologies Advances Quantum Diamond and Two-Dimensional Phosphorus Material Capabilities

ViQium Technologies Co., Ltd., founded in 2025 and headquartered in Minhang District, Shanghai, China, continues to strengthen its position in the quantum materials sector through ongoing advances in nitrogen-vacancy (NV) center quantum diamond materials and emerging two-dimensional phosphorus-based materials. Operating under the brand name ViQium, the company supports research institutions and industrial partners worldwide through a global service network that spans material selection to successful application deployment.

ViQium’s strategic focus centers on the exploration, scalable fabrication, and industrial application of quantum diamonds alongside emerging two-dimensional phosphorus-based materials. The company’s founding team draws on academic backgrounds from several leading universities in China, with more than eight years of dedicated research in advanced quantum materials, including NV center quantum diamonds and black phosphorus. This depth of experience has allowed the team to develop differentiated technological capabilities across key stages of quantum material development, from material synthesis and defect engineering to device integration.

Proprietary Color Center Engineering Closes the Performance Gap

One of the most notable developments at ViQium is the establishment of a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This proprietary advanced color center engineering capability allows ViQium to offer medium- to high-density NV center diamond products ranging from 0.1 to 5 ppm, as well as ultra-high-density NV center diamond products ranging from 10 to 45 ppm. These products achieve high ODMR contrast performance, with key parameters comparable to leading international suppliers such as the E6 product series.

Traditional domestic NV diamond suppliers have generally been limited to producing basic medium- to high-density NV center samples, facing challenges in NV center density control, spatial uniformity, and ODMR contrast performance. International suppliers, while offering high-performance high-density products, often come with higher costs and limited flexibility for small-batch customization. ViQium addresses this gap by supporting flexible customization starting from a single piece, offering significantly lower pricing than imported alternatives while balancing high performance with flexible procurement requirements. These capabilities directly serve quantum precision magnetometry, industrial non-destructive testing, and other high-performance sensing applications.

Integrated End-to-End Delivery from Materials to Complete Solutions

ViQium’s technical team combines expertise in both diamond material engineering and quantum measurement technologies, establishing an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. This stands in contrast to many market suppliers who focus primarily on material sales with limited expertise in downstream applications such as ODMR system integration, parameter optimization, and magnetic field calibration.

Based on customer requirements, ViQium provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, delivering long-term technical support throughout the customer’s research and development process. This end-to-end approach particularly benefits university research groups without prior NV center experimental experience, as well as companies developing NV-based quantum precision measurement technologies.

Expanding the Flexible Customization Platform

ViQium continues to broaden its comprehensive product portfolio, which covers high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds. Customers can specify dimensions and NV center concentration according to their experimental requirements. Standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days, supporting fundamental research, emerging quantum sensing development, and small-scale prototype development.

Intellectual Property Foundation Underpins Technology Independence

Through years of technological development, ViQium has built a systematic patent strategy designed to safeguard technological independence and ensure a secure development pathway. In the phosphorus-based materials domain, the company has developed controllable fabrication technologies for black phosphorus/silver nanowire heterostructure composites and phosphorus-doped thermoelectric materials, alongside capabilities in preparing and applying emerging low-dimensional phosphorus-based materials such as germanium triphosphide (GeP₃) nanosheets/nanowires and tin triphosphide (SnP₃) nanosheets.

In diamond quantum materials, ViQium has established a comprehensive technology platform for fabricating NV centers through high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) methods, enabling controllable fabrication ranging from single NV centers with coherence times exceeding 200 μs to ppm-level high-concentration NV center ensembles. The company also holds patented technologies for damage-free fabrication of nitrogen-vacancy centers in diamond, alongside large-scale phosphide single crystal growth technologies for materials including GeP and SnP₃.

The Science Behind NV Center Sensing

ViQium’s core technology relies on nitrogen-vacancy centers in quantum diamond, a quantum defect system embedded within the diamond lattice that functions through three fundamental steps: optical initialization, microwave-based quantum manipulation, and optical readout. A green laser initializes the NV center’s quantum state; a precisely tuned microwave field then manipulates that state by adjusting frequency and duration; finally, laser excitation produces red fluorescence whose intensity varies with the final quantum state, allowing extraction of information about surrounding physical changes.

The key advantages of NV centers lie in room-temperature operation and nanoscale sensing resolution, making them suitable for quantum sensing, biological imaging, and precision measurement without reliance on cryogenic temperatures or complex vacuum systems. Their sensitivity to magnetic fields, temperature, and electric fields positions NV centers as high-resolution quantum sensors for both scientific research and industrial applications.

Global Service Network and Customer Support

ViQium has established a comprehensive service framework covering requirement alignment, solution design, sample validation, delivery implementation, and application support. This end-to-end process typically progresses through technical communication, solution matching, sample validation, and batch delivery, with timelines ranging from several weeks to several months depending on application complexity.

The company provides tailored technical training on material characteristics, operating procedures, and experimental considerations, supported by a collaborative technical mechanism between sales and R&D teams for rapid response to urgent challenges. ViQium also implements batch-level control and traceability management throughout NV center quantum diamond production, ensuring performance stability across material batches, alongside internal access control mechanisms to protect customer technical and application data.

Serving Research, Industrial, and Aerospace Customers

ViQium’s quantum diamond materials and precision measurement instruments serve semiconductor inspection, power metrology, geological exploration, and aerospace and defense applications, enabling sensitive detection of magnetic fields, electric currents, temperature, and stress. For research institutes and universities, ViQium addresses challenges of unstable experimental results and insufficient reproducibility through reproducible, high-quality materials. For industrial inspection and precision manufacturing companies, ViQium supports the transition from conventional measurement toward high-sensitivity, non-invasive, real-time sensing. As ViQium’s material and instrument portfolio continues to mature, the company remains focused on bridging laboratory breakthroughs with industrial-scale implementation across its Quantum Materials Series and Precision Instruments offerings.
