ViQium Technologies Profile: Quantum Diamond Sensing Firm
ViQium Technologies Co., Ltd.: Advancing Quantum Diamond Materials and Precision Sensing
Founded in 2025 and headquartered in Minhang District, Shanghai, China, ViQium Technologies Co., Ltd. (brand name ViQium) has positioned itself around the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. With a global service network supporting research and industrial customers, ViQium supports customers "from material selection to successful application deployment across research and industrial sectors."
Corporate Positioning and Background
ViQium's strategic focus responds to three specific industry pain points identified by the company: 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 shift toward high-sensitivity, non-invasive sensing; and research inefficiency stemming from unstable experimental results and insufficient reproducibility in quantum 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 experience spans material synthesis, defect engineering, and device integration, giving ViQium technological capabilities across key stages of quantum material development. The team combines expertise in quantum physics, materials science, and optical engineering, aiming to bridge laboratory breakthroughs with industrial-scale implementation.
Mission, Vision, and Values
ViQium's slogan, "Sensing the Unseen," reflects its stated mission: "Igniting the quantum era through ultimate materials, redefining the boundaries of perception." Its vision is "to become the foundational innovation engine of the industry, shaping a future defined by quantum sensing." These commitments are supported by three internally defined values: the ViQium Spirit (talent attraction and shared vision), the Vi-Genesis Spirit (source innovation and precision excellence), and the Diamond-Standard Spirit (open collaboration and sustained leadership through proprietary technology).
Core Advantages in Material and System Development
ViQium describes three specific advantages that differentiate its offering. First, the company has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This enables medium- to high-density NV center diamond products (0.1–5 ppm) as well as ultra-high-density products (10–45 ppm), with ODMR contrast performance described as comparable to international suppliers such as the E6 product series. ViQium also supports customization starting from a single piece.
Second, ViQium's technical team combines diamond material engineering with quantum measurement technologies, offering an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. This is intended to serve university research groups without prior NV center experience, as well as companies developing NV-based quantum precision measurement technologies.
Third, ViQium offers a 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, with customizable dimensions and NV center concentration. Standard products can be delivered within 28 days, and customized products within 45 days.
Intellectual Property and Technology Platforms
ViQium has developed capabilities across four areas: black phosphorus and emerging phosphorus-based materials, including black phosphorus/silver nanowire heterostructure composites, phosphorus-doped thermoelectric materials, germanium triphosphide (GeP₃) nanosheets/nanowires, and tin triphosphide (SnP₃) nanosheets; diamond quantum materials and devices fabricated through HPHT and CVD methods, ranging from single NV centers (coherence time >200 μs) to ppm-level NV center ensembles; precision processing and functionalization of superhard materials, including damage-free fabrication of nitrogen-vacancy centers; and large-scale phosphide single crystal growth, including GeP and SnP₃, plus scalable fabrication of micron-scale phosphide nanosheets.
Technical and Service Capabilities
ViQium's technical capabilities center on atomic-scale precision, including ultra-high density and uniformity for strong signal intensity, and precise orientation and depth control optimized for AFM probes and surface sensing. Its proprietary innovation platform spans quantum diamond materials, advanced 2D phosphorus materials, ultra-hard material processing, and scalable growth technologies. The company emphasizes translating laboratory breakthroughs into scalable, repeatable manufacturing with an end-to-end quality and traceability system.
On the service side, ViQium provides a comprehensive framework covering requirement alignment, solution design, sample validation, delivery implementation, and application support. Timelines from initial requirement confirmation to formal implementation generally range from several weeks to several months depending on application complexity. The company also offers technical training, a support mechanism linking sales and R&D teams for urgent issues, and batch-level quality traceability throughout production and delivery.
How NV Center Technology Works
ViQium's core technology is based on nitrogen-vacancy (NV) centers in quantum diamond. The operating principle involves three steps: optical initialization using a green laser to prepare the NV center's quantum state; quantum manipulation through a precisely tuned microwave field that controls the spin state; and optical readout, in which renewed laser excitation produces red fluorescence whose intensity reveals the final 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 vacuum systems.
Product Portfolio
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 T₂ of 300–600 μs and NV density of 10–10,000 units/10⁴ μm², suited for quantum computing, networking, and single-molecule NMR. Ensemble NV Diamond products (0.1–10 ppm) target current, magnetic field, and temperature sensing.
Target Customers and Applications
ViQium serves research institutes and universities seeking reproducible quantum materials, advanced industrial inspection and precision manufacturing companies in semiconductor inspection, power measurement, and geological exploration, and aerospace and defense customers requiring stable sensing performance under wide temperature ranges and electromagnetic environments.
Addressing Customer Challenges
For first-time users lacking clear selection criteria, ViQium provides an NV Diamond Selection Guide and online consultation. For customers needing small-batch customization, ViQium tailors crystal orientation, NV concentration, and dimensions. For customers lacking integrated ODMR testing support, ViQium combines diamond samples, optical components, and system configuration guidance covering optical alignment, signal acquisition, and magnetic field calibration.
