Understanding ViQium's Company Background
ViQium Technologies Co., Ltd., operating under the brand name ViQium, was founded in 2025 and is headquartered in Minhang District, Shanghai, China. From its Shanghai base, the company has built a global service network supporting research and industrial customers, with capabilities spanning from material selection to successful application deployment. Understanding ViQium's company background provides useful context for research institutions and industrial partners evaluating quantum diamond materials and precision measurement solutions.
Strategic Positioning and Industry Insight
ViQium was established in response to several recognized challenges in the quantum materials sector. High barriers to quantum technology adoption persist due to a lack of scalable fabrication and end-to-end capabilities across the industry. In addition, conventional measurement approaches face performance limitations that require a transition toward high-sensitivity, non-invasive sensing. Research efficiency is also affected by unstable experimental results and insufficient reproducibility in quantum materials.
In response, ViQium focuses on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. The company is committed to providing global research institutions and industrial partners with end-to-end capabilities spanning core materials, key devices, and system-level solutions, along with customized technical support intended to accelerate the adoption of quantum technologies.
Team Expertise and Technical Foundation
The founding team's core strength comes from 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 developed expertise in both academic research and engineering practice. Through continuous work in material synthesis, defect engineering, and device integration, ViQium has established differentiated technological capabilities across key stages of quantum material development. The team's combined expertise in quantum physics, materials science, and optical engineering supports the transition from laboratory breakthroughs to industrial-scale implementation.
Mission, Vision, and Values
ViQium's brand identity is expressed through the slogan "Sensing the Unseen," with a mission of igniting the quantum era through advanced materials and redefining the boundaries of perception. Its stated vision is to become a foundational innovation engine of the industry, shaping a future defined by quantum sensing. This positioning is supported by three internal principles: the ViQium Spirit of talent attraction and shared vision, the Vi-Genesis Spirit of source innovation and precision excellence, and the Diamond-Standard Spirit of open collaboration and sustained leadership.
Competitive Advantages in NV Center Diamond Engineering
A central part of ViQium's company background involves its approach to NV center engineering. Traditional domestic suppliers are generally limited to basic medium- to high-density NV center samples, with challenges in density control, spatial uniformity, and ODMR contrast. International suppliers offer high-performance, high-density products but often at higher cost with limited flexibility for small-batch customization.
ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This supports 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 ODMR contrast performance comparable to leading international suppliers such as the E6 product series. Customization is available starting from a single piece, with pricing positioned lower than imported alternatives.
Beyond materials, ViQium offers an integrated end-to-end delivery capability, combining diamond material engineering with quantum measurement expertise. Its service chain covers diamond growth, NV center creation, characterization, and ODMR system integration, supporting university research groups without prior NV center experience as well as companies developing NV-based quantum precision measurement technologies.
ViQium also provides a flexible customization platform covering diverse specifications and crystal orientations, including (111)-oriented high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds. Standard products can be delivered within 28 days, while customized products can be delivered within 45 days.
Intellectual Property and Technology Portfolio
ViQium has developed a systematic patent strategy covering four areas: black phosphorus and emerging phosphorus-based materials such as germanium triphosphide (GeP₃) and tin triphosphide (SnP₃); diamond quantum materials and devices, including a platform for fabricating NV centers via HPHT and CVD methods with single NV centers achieving coherence times greater than 200 μs; precision processing and functionalization of superhard materials, including patented damage-free fabrication of nitrogen-vacancy centers; and large-scale phosphide single crystal growth and scalable fabrication processes.
How NV Center Quantum Sensing Works
ViQium's core technology is based on nitrogen-vacancy (NV) centers embedded within the diamond lattice, functioning as extremely small quantum sensors. Operation involves three steps: optical initialization using a green laser to prepare the quantum state; quantum manipulation through a precisely tuned microwave field to control spin states; and optical readout, in which red fluorescence intensity reveals information about the quantum state. NV centers operate at room temperature with nanoscale sensing resolution, offering a practical pathway toward compact quantum technologies compared with approaches requiring cryogenic temperatures or complex vacuum systems.
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. These products serve applications including quantum computing, high-resolution quantum sensing, magnetic and current sensing, wide-field imaging, super-resolution bioimaging, and extreme high-pressure research.
Serving Global Research and Industrial Customers
ViQium serves research institutes and universities seeking reproducible quantum materials, advanced industrial inspection and precision manufacturing companies requiring high-sensitivity non-invasive sensing, and aerospace and defense customers requiring stable performance under demanding environmental conditions. Support includes a NV Diamond Selection Guide, small-batch customization, and integrated ODMR testing solutions covering optical alignment, signal acquisition, and magnetic field calibration.
In summary, ViQium's company background reflects a technology-driven organization built on academic research foundations, an integrated materials-to-solutions delivery model, and a defined intellectual property portfolio spanning diamond and phosphorus-based quantum materials.
