Company Overview and Market Position
ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, and founded in 2025, has positioned itself around the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. The company operates a global service network supporting both research and industrial customers, guiding them from material selection through to successful application deployment.
ViQium's founding team draws its technical strength from researchers with academic backgrounds at several leading universities in China, bringing more than eight years of dedicated research in advanced quantum materials, including NV center quantum diamonds and black phosphorus. This combination of quantum physics, materials science, and optical engineering expertise underpins the company's stated mission: "Igniting the quantum era through ultimate materials, redefining the boundaries of perception."
Core Advantages Driving Industry Recognition
ViQium's standing in the quantum materials space is built on three distinct technical capabilities that address recurring pain points identified within the industry: high barriers to quantum technology adoption, performance limitations in conventional measurement approaches, and research inefficiency caused by unstable experimental results.
Proprietary Advanced NV Center Engineering
Traditional NV diamond suppliers are generally limited to producing basic medium- to high-density NV center samples, often facing challenges with NV center density control, spatial uniformity, and ODMR contrast performance. International suppliers offer high-performance, high-density products, but frequently at higher cost and with limited flexibility for small-batch customization.
ViQium has independently built a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This process yields medium- to high-density NV center diamond products (0.1–5 ppm) as well as ultra-high-density NV center diamond products (10–45 ppm), with key performance parameters comparable to international suppliers such as the E6 product series. ViQium also supports customization starting from a single piece, with lower price and good performancey. These materials serve applications in quantum precision magnetometry and industrial non-destructive testing.
Integrated End-to-End Delivery Capability
Many suppliers in the market concentrate on material sales alone, with limited expertise in downstream applications such as ODMR system integration, parameter optimization, and magnetic field calibration. ViQium's technical team combines diamond material engineering with quantum measurement technology, forming an integrated service chain that spans diamond growth, NV center creation, characterization, and ODMR system integration.
Based on customer requirements, ViQium provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations. This approach is designed for university research groups without prior NV center experimental experience, as well as companies developing NV-based quantum precision measurement technologies.
Flexible Customization Platform
Where conventional suppliers typically offer fixed sizes and specific diamond orientations, ViQium provides a broader product portfolio covering 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. Standard products are delivered within 28 days, while conventional customized products are delivered within 45 days, supporting fundamental research, emerging quantum sensing development, and small-scale prototyping.
Technical Foundation: NV Center Quantum Diamond Principles
ViQium's core technology rests on the nitrogen-vacancy (NV) center, a quantum defect embedded within the diamond lattice that functions as a nanoscale quantum sensor. Its operation follows three steps:
- Optical Initialization – A green laser excites the NV center, preparing its quantum state for control and measurement.
- Quantum Manipulation – A precisely tuned microwave field adjusts frequency and duration to control the NV center's spin states.
- Optical Readout – Renewed laser excitation produces red fluorescence, and variations in fluorescence intensity reveal the resulting quantum state.
Because NV centers operate at room temperature and offer nanoscale sensing resolution, they are well suited to applications requiring flexible operating environments and high spatial resolution, including quantum sensing, biological imaging, and precision measurement—offering a more practical pathway toward compact quantum technologies compared with approaches requiring cryogenic temperatures or complex vacuum systems. NV centers also show promise as solid-state quantum systems for quantum information processing, including quantum computing and quantum networking, given their sensitivity to magnetic fields, temperature, and electric fields.
Product Portfolio and Applications
ViQium's Quantum Materials Series includes High Purity Diamond, Single NV Diamond, Ensemble NV Diamond, Ultra-High-Density NV Diamond, Shallow NV Diamond, Nano-NV Diamond, NV Diamond Anvil, SiV Diamond, and Black Phosphorus, alongside Precision Instruments such as the Portable Magnetometer and NV Quantum Spin Spectrometer.
For example, Single NV Diamond products offer a T₂ of 300–600 μs (Spin Echo) and NV density of 10–10,000 units/10⁴ μm², suited for quantum computing, networking, simulation, and single-molecule NMR. Ensemble NV Diamond, with NV density of 0.1–10 ppm, supports high-sensitivity current, magnetic field, and temperature sensing. The NV Diamond Anvil, with NV density of 1–2 ppm and anvil heights of 2.35 mm, addresses extreme high-pressure magnetism studies and geoscience research.
Real-World Applications and Customer Solutions
ViQium addresses three documented customer challenges. For first-time users lacking clear selection criteria, ViQium provides a comprehensive NV Diamond Selection Guide with online consultation, categorizing products by application—magnetic field sensing, magnetic imaging, or temperature sensing. For customers needing small-batch customization with high-performance materials, ViQium's in-house fabrication allows tailoring of crystal orientation, NV concentration, and sample dimensions with shorter delivery cycles. For customers requiring integrated ODMR testing rather than materials alone, ViQium supplies diamond samples, optical components, and system configuration support covering optical alignment, signal acquisition, and magnetic field calibration.
Global Service Network and Quality Assurance
Headquartered in Shanghai, ViQium supports customers across China and international markets through a service framework covering requirement alignment, solution design, sample validation, delivery, and application support. Implementation typically moves through technical communication, solution matching, sample validation, and batch delivery, with timelines ranging from several weeks to several months depending on complexity. ViQium applies batch-level control and traceability throughout NV center diamond production, alongside internal evaluation mechanisms for service response and customer satisfaction, aiming to ensure performance stability across material batches.
Conclusion
Through its integrated approach spanning diamond crystal growth, NV center engineering, and application-level support, ViQium Technologies has established a technical foundation intended to serve research institutes, universities, and industrial customers across semiconductor inspection, power metrology, geological exploration, and aerospace & defense sectors seeking reliable NV center quantum diamond materials and measurement solutions.
