Addressing a Critical Gap in Quantum Technology Adoption
The quantum sensing industry faces a persistent challenge: high barriers to quantum technology adoption due to a lack of scalable fabrication and end-to-end capabilities. Many research teams and industrial partners find that conventional measurement approaches reach their performance limits, requiring a transition toward high-sensitivity, non-invasive sensing. ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, has positioned itself around solving exactly this problem—focusing on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials.
ViQium's founding team brings together 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. This combination of quantum physics, materials science, and optical engineering expertise underpins the company's mission: igniting the quantum era through ultimate materials, redefining the boundaries of perception—captured in its slogan, "Sensing the Unseen."
A Technology Platform Built on NV Center Quantum Diamonds
At the core of ViQium's innovative solutions is the nitrogen-vacancy (NV) center, a quantum defect system embedded within the diamond lattice that functions as an extremely small quantum sensor. The operating principle unfolds in three steps: optical initialization using a green laser to set the NV center's quantum state, microwave-based quantum manipulation to precisely control spin states, and optical readout through red fluorescence to extract information about surrounding physical changes such as magnetic fields, temperature, and electric fields.
Because NV centers operate at room temperature with nanoscale sensing resolution, they offer a more practical pathway toward compact and scalable quantum technologies compared with approaches that depend on cryogenic temperatures or complex vacuum systems. This principle underlies ViQium's product portfolio, which spans quantum sensing applications as well as emerging opportunities in quantum information processing.
Three Pillars of Differentiation
ViQium's competitive position rests on three structural advantages developed through years of in-house engineering:
First, proprietary advanced color center engineering gives ViQium a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. The company offers 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 with key parameters comparable to leading international suppliers' product series—while supporting flexible customization starting from a single piece at more competitive pricing.
Second, ViQium delivers integrated end-to-end capability, extending beyond material sales into ODMR system integration, parameter optimization, and magnetic field calibration. The technical team provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, supporting university research groups without prior NV center experience as well as companies developing NV-based quantum precision measurement technologies.
Third, ViQium operates 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—addressing specialized experimental requirements that fixed-size, fixed-orientation suppliers often cannot accommodate.
A Comprehensive Product Matrix
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. Each product is engineered for specific use cases: Single NV Diamond supports quantum computing, networking, simulation, high-resolution quantum sensing, and single-molecule NMR, with coherence time (T₂) of 300–600 μs; Ensemble NV Diamond is suited for high-sensitivity precision sensing of current, magnetic field, and temperature; and Ultra-High-Density NV Diamond, with NV density of 10–45 ppm, supports quantum memory and room-temperature solid-state masers. The Shallow NV Diamond line serves wide-field current imaging, wide-field magnetic imaging, and ultrafast nonlinear photonic sensing, while Micro-nano NV Diamond products support super-resolution bioimaging, intracellular quantum sensing, and miniaturized magnetometers. The NV Diamond Anvil, with anvil faces ranging from 20 μm to 300 μm, addresses 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 and an NV Quantum Spin Spectrometer for nanoscale magnetic resonance analysis down to single-spin sensitivity.
Solving Real Customer Challenges
Feedback gathered from research and industrial customers points to three recurring obstacles that ViQium's solutions directly address. For first-time users, selecting suitable NV diamond materials can be challenging due to a lack of clear reference standards; ViQium responds with a comprehensive NV Diamond Selection Guide and online consultation services, categorizing products by application—magnetic field sensing, magnetic imaging, or temperature sensing—so customers avoid purchasing multiple samples just for comparison.
A second challenge involves limited access to small-batch customization alongside high-performance materials, since many established suppliers do not support small-volume orders or fall short on parameters such as NV concentration, uniformity, and coherence time. ViQium combines flexible small-batch customization with in-house fabrication, tailoring crystal orientation, NV concentration, sample dimensions, and microstructure processing to specific requirements.
Third, many suppliers in the market sell diamond materials without integrated ODMR testing support. ViQium's team offers an integrated solution combining diamond samples, optical components, and system configuration support—covering optical alignment, signal acquisition, and magnetic field calibration—so customers can obtain both materials and testing solutions from a single provider.
Serving Research, Industry, and Defense
ViQium's target customers span three profiles. Research institutes and universities prioritize high-quality, reproducible materials and accessible experimental platforms to overcome unstable experimental results. Advanced industrial inspection and precision manufacturing companies—in semiconductor inspection, power measurement, and geological exploration—seek system integration, long-term reliability, and scalable supply to move beyond measurement approaches that are functional but insufficiently precise for industrial deployment. Aerospace and defense customers require highly sensitive detection and stable performance across wide temperature ranges and challenging electromagnetic environments, with decisions driven by technical security and proven long-term reliability.
A Foundation for the Quantum Sensing Era
Guided by its vision to become a foundational innovation engine shaping a future defined by quantum sensing, ViQium continues to build on its intellectual property foundation across black phosphorus and emerging phosphorus-based materials, diamond quantum materials and devices, precision processing of superhard materials, and large-scale phosphide single crystal growth. By combining material-level engineering with system-level integration support, ViQium offers a pathway for customers to move from material selection to successful application deployment—whether in fundamental research, industrial sensing, or extreme-environment detection.
