ViQium Technologies Co., Ltd., operating under the brand name ViQium, is headquartered in Minhang District, Shanghai, China. From this base, the company has built a global service network that supports research and industrial customers across China and key international markets, guiding partners through every stage of the quantum materials journey—from initial material selection to successful application deployment.
Corporate Positioning and Technical Foundations
ViQium focuses on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. The company was founded to address three recurring industry pain points: 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 toward high-sensitivity, non-invasive sensing; and research inefficiency driven by unstable experimental results and insufficient reproducibility in quantum materials.
To solve these challenges, ViQium provides global research institutions and industrial partners with end-to-end capabilities spanning core materials, key devices, and system-level solutions, supported by customized technical assistance designed to accelerate the adoption of quantum technologies.
The company’s founding team is composed of researchers with 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—the team has built expertise across material synthesis, defect engineering, and device integration. This combination of quantum physics, materials science, and optical engineering knowledge allows ViQium to bridge laboratory breakthroughs with industrial-scale implementation, from the Shanghai headquarters outward to its global customer base.
Core Competitive Advantages
Proprietary Color Center Engineering
ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This process supports 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 high ODMR contrast performance. ViQium also supports flexible customization starting from a single piece, which helps balance 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
ViQium’s technical team combines expertise in diamond material engineering and quantum measurement technologies, forming an integrated service chain that covers diamond growth, NV center creation, characterization, and ODMR system integration. Based on customer requirements, the company provides customized material selection, testing solutions, benchmarking information, and experimental optimization recommendations, offering 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 Platform
ViQium offers a comprehensive product portfolio covering (111)-oriented high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds. Specifications such as diamond dimensions and NV center concentration can be customized to specific experimental requirements. Standard products can be delivered within 28 days, while customized products can typically be delivered within 45 days, supporting fundamental research, emerging quantum sensing development, and small-scale prototype work.
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 specific parameters—for example, Single NV Diamond offers a T₂ of 300–600 μs and NV density of 10–10,000 units per 10⁴ μm², suited for quantum computing, networking, simulation, high-resolution quantum sensing, and single-molecule NMR. Ensemble NV Diamond, with NV density between 0.1 and 10 ppm, supports high-sensitivity precision sensing for current, magnetic field, and temperature measurement. Ultra-High-Density NV Diamond reaches 10–45 ppm NV density for sensing and room-temperature solid-state maser applications. High Purity Diamond, with nitrogen content below 5 ppb and boron content below 1 ppb, serves semiconductor, electronics, and optical window applications. Shallow NV Diamond supports wide-field current and magnetic imaging, while Micro-nano NV Diamond is suited to super-resolution bioimaging and miniaturized sensing devices. NV Diamond Anvil products support extreme high-pressure magnetism studies and geoscience research.
ViQium is also developing Precision Instruments, including a Portable Magnetometer for room-temperature, high-sensitivity magnetic field measurement in a compact, low-power system, and an NV Quantum Spin Spectrometer, a nanoscale magnetic resonance platform built on diamond NV center ODMR technology for spin detection, mapping, and coherence analysis.
Technical Principles Behind NV Center Quantum Diamonds
ViQium’s core technology relies on nitrogen-vacancy (NV) centers in quantum diamond, a quantum defect system embedded within the diamond lattice. The operating principle involves three steps: optical initialization using green laser excitation to prepare the NV center’s quantum state; microwave-based quantum manipulation to control spin states through precisely tuned frequency and duration; and optical readout, where renewed laser excitation produces red fluorescence whose intensity reveals the final quantum state. Because NV centers operate at room temperature and offer nanoscale sensing resolution, they are well suited for applications requiring flexible operating environments and high spatial resolution, including quantum sensing, biological imaging, and precision measurement, while also showing promise for quantum information processing such as quantum computing and quantum networking.
Industry Applications and Customer Support
From its Shanghai headquarters, ViQium supports applications including semiconductor inspection, power metrology, geological exploration, and aerospace and defense, enabling sensitive detection of weak physical parameters such as magnetic fields, electric currents, temperature, and stress. Research institutes and universities rely on ViQium for reproducible quantum materials and accessible experimental platforms. Advanced industrial inspection and precision manufacturing companies depend on ViQium’s system integration, long-term reliability, and scalable supply capacity. Aerospace and defense customers look to ViQium for stable sensing performance under wide temperature ranges and challenging electromagnetic environments.
ViQium’s service framework covers requirement alignment, solution design, sample validation, delivery implementation, and application support, supplemented by tailored technical training, collaborative support channels between sales and R&D teams, batch-level quality traceability, and ongoing service evaluation. Through this structured approach, ViQium Technologies, based in Minhang District, Shanghai, continues to extend its global service network, helping research and industrial customers move from material selection to successful, reproducible quantum sensing applications.
