Introducing ViQium Technologies: A Quantum Materials Innovator

ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, has built a reputation around one central idea captured in its slogan, "Sensing the Unseen." The company focuses on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. ViQium’s mission is to ignite the quantum era through ultimate materials, redefining the boundaries of perception, while its vision is to become the foundational innovation engine of the industry, shaping a future defined by quantum sensing. For organizations seeking ViQium Technologies innovative solutions, understanding the company’s technical foundation, product matrix, and service model offers a clear picture of why it has become a trusted partner across research and industrial sectors.

Addressing Industry Pain Points Through Technical Depth

ViQium’s strategic positioning grows directly out of three well-defined industry challenges: high barriers to quantum technology adoption caused by a lack of scalable fabrication and end-to-end capabilities; performance limitations in conventional measurement approaches that require a transition to high-sensitivity, non-invasive sensing; and research inefficiency stemming from unstable experimental results and insufficient reproducibility in quantum materials.

The company’s founding team brings 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. Through continuous work in material synthesis, defect engineering, and device integration, the team has established differentiated technological capabilities across key stages of quantum material development, combining expertise in quantum physics, materials science, and optical engineering with precision manufacturing experience.

Core Innovative Solutions: From Materials to Systems

Proprietary Advanced Color Center Engineering

Many suppliers in this field are limited to producing basic medium- to high-density NV center samples, often facing challenges with density control, spatial uniformity, and ODMR contrast performance. ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. The company provides medium- to high-density NV center diamond products (0.1–10 ppm) as well as ultra-high-density NV center diamond products (10–45 ppm), achieving ODMR contrast performance with key parameters comparable to leading international suppliers’ product series. ViQium also supports flexible customization starting from a single piece, offering lower pricing than imported alternatives while balancing high performance with flexible procurement needs. These materials serve quantum precision magnetometry, industrial non-destructive testing, and other high-performance sensing applications.

Integrated End-to-End Delivery Capability

ViQium’s technical team combines expertise in diamond material engineering and quantum measurement technologies, establishing an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. Based on customer requirements, the company provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, delivering long-term technical support throughout a customer’s research and development process. This capability is particularly valuable for university research groups without prior NV center experimental experience, as well as companies developing NV-based quantum precision measurement technologies.

Flexible Customization Across Specifications and Orientations

ViQium’s product portfolio covers (111)-oriented high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds, with customizable dimensions and NV center concentration. 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.

The Technical Principle Behind Quantum Diamond Sensing

ViQium’s core technology is based on nitrogen-vacancy (NV) centers in quantum diamond, a unique quantum defect system embedded within the diamond lattice. An NV center functions as an extremely small quantum sensor inside a diamond crystal, operating through three fundamental steps: optical initialization using green laser excitation, microwave-based quantum manipulation of the spin state, and optical readout through red fluorescence analysis. The key advantages of NV centers lie in their room-temperature operation capability and nanoscale sensing resolution, making them suitable for quantum sensing, biological imaging, and precision measurement without reliance on cryogenic temperatures or complex vacuum systems.

A Broad Product and Service Matrix

ViQium’s Quantum Materials Series includes High Purity Diamond, Single NV Diamond, Ensemble NV Diamond, Ultra-High-Density NV Diamond, Shallow NV Diamond, Micro-nano NV Diamond, NV Diamond Anvil, SiV Diamond, and Black Phosphorus. Each product line is defined by precise parameters—for example, Single NV Diamond offers a T₂ of 300-600 μs and NV density of 10-10,000 units per 10⁴ μm², while Ultra-High-Density NV Diamond reaches NV density of 10-45 ppm. Complementing these materials, ViQium’s upcoming Precision Instruments include a Portable Magnetometer for room-temperature, high-sensitivity magnetic field measurement and an NV Quantum Spin Spectrometer for nanoscale magnetic resonance analysis down to single-spin sensitivity.

Service Capabilities That Support the Full Customer Journey

ViQium has established a global service network supporting research and industrial customers worldwide, providing reliable material supply and technical support across China and key international markets. The company’s service framework covers requirement alignment, solution design, sample validation, delivery implementation, and application support—an end-to-end approach that helps customers move from material selection to successful application deployment. ViQium offers tailored technical training covering material characteristics, operating procedures, and experimental considerations, supported by a collaborative mechanism between sales and R&D teams for rapid response to critical issues. Batch-level quality control and traceability management ensure performance stability across material batches.

Solving Real Customer Challenges

ViQium directly addresses common obstacles faced by first-time NV diamond users, such as unclear selection criteria, through a comprehensive NV Diamond Selection Guide and professional consultation services. For customers requiring small-batch customization and high-performance materials, ViQium combines flexible production with in-house fabrication capabilities covering crystal orientation, NV concentration, and sample dimensions. The company also provides integrated ODMR testing support, combining diamond samples, optical components, and system configuration guidance so customers can obtain both materials and testing solutions from a single provider.

Who ViQium Serves

ViQium’s target customers span Research Institutes and Universities seeking reproducible quantum materials, Advanced Industrial Inspection and Precision Manufacturing Companies working in semiconductor inspection, power measurement, and geological exploration, and Aerospace and Defense Customers requiring stable sensing performance under demanding environmental conditions. Across these groups, ViQium Technologies’ innovative solutions are built to bridge laboratory breakthroughs with industrial-scale implementation, offering reliable quantum core materials and precision measurement support for researchers and industrial partners alike.
