Researchers and industrial teams searching for a compact NV center quantum sensor laboratory setup face a recurring dilemma: conventional measurement tools cannot deliver the sensitivity, spatial resolution, or non-invasive performance that modern quantum sensing demands. ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, has positioned itself directly against this gap by focusing on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials.
Company Background and Strategic Positioning
ViQium'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. Through continuous work in material synthesis, defect engineering, and device integration, the company has built differentiated technological capabilities across key stages of quantum material development—spanning quantum physics, materials science, and optical engineering. This combination allows ViQium to bridge laboratory breakthroughs with industrial-scale implementation, providing global research institutions and industrial partners with core materials, key devices, and system-level solutions, supported by a global service network for research and industrial customers worldwide.
How NV Center Quantum Sensors Work
At the core of ViQium's technology is the nitrogen-vacancy (NV) center, a quantum defect embedded within the diamond lattice that functions as an extremely small quantum sensor. Its operation follows three steps: optical initialization, where a green laser prepares the NV center's quantum state; quantum manipulation, where a precisely tuned microwave field adjusts the spin state through controlled frequency and duration; and optical readout, where re-excitation with laser light produces red fluorescence whose intensity reveals the final quantum state. Because NV centers operate at room temperature with nanoscale sensing resolution, they offer a practical pathway toward compact and scalable quantum technologies compared with approaches requiring cryogenic temperatures or complex vacuum systems—an important consideration for any compact NV center quantum sensor laboratory setup. Their sensitivity to magnetic fields, temperature, and electric fields also positions NV centers as promising building blocks for quantum information processing, including quantum computing and quantum networking.
Core Advantages for Laboratory and Industrial Users
Proprietary Advanced Color Center Engineering
ViQium has independently established 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. Customization is supported starting from a single piece, addressing customers who need high performance without committing to large batch orders. Applications include quantum precision magnetometry and industrial non-destructive testing.
Integrated End-to-End Delivery Capability
Rather than limiting itself to material sales, ViQium's technical team combines diamond material engineering with quantum measurement expertise. The company has established an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. Customers receive customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, along with long-term technical support—particularly valuable for university research groups without prior NV center experimental experience.
Flexible Customization Platform
ViQium's product portfolio covers (111)-oriented 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, while conventional customized products can be delivered within 45 days, supporting fundamental research, emerging quantum sensing development, and small-scale prototype work.
Product Portfolio Supporting Compact NV Center Quantum Sensor Laboratories
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. Single NV Diamond products, suited for quantum computing, networking, simulation, and single-molecule NMR, offer T₂ of 300–600 μs (Spin Echo) and T₂* of 1 μs (FID), with NV density of 10–10,000 units per 10⁴ μm². Ensemble NV Diamond, designed for high-sensitivity current, magnetic field, and temperature sensing, provides T₂ of 30–250 μs and NV density of 0.1–10 ppm. High Purity Diamond substrates maintain nitrogen content below 5 ppb, boron content below 1 ppb, and carbon-12 enrichment of 98.9%. Shallow NV Diamond, used in wide-field current and magnetic imaging, offers NV depth control between 10–50 nm or 1–10 μm. Every listed product includes factory calibration and characterization data alongside product customization services.
Addressing Common Customer Challenges
For first-time users, selecting suitable NV diamond materials without clear reference standards can be difficult. ViQium addresses this through a comprehensive NV Diamond Selection Guide and professional online consultation, categorizing products by application—magnetic field sensing, magnetic imaging, or temperature sensing—so customers avoid purchasing multiple samples for comparison.
A second recurring challenge involves limited access to small-batch customization combined with high performance, since many suppliers offering small-batch production still show gaps in 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.
A third challenge is the lack of integrated ODMR testing and experimental support among suppliers who focus solely on material sales. ViQium provides diamond samples, optical components, and system configuration support together, covering optical alignment, signal acquisition, and magnetic field calibration, so customers can obtain both materials and testing solutions from a single provider.
Industries and Customer Profiles Served
NV center quantum diamond technology primarily serves quantum precision measurement and advanced sensing, spanning fundamental scientific research, industrial precision inspection, and extreme-environment detection. ViQium supports semiconductor inspection, power metrology, geological exploration, and aerospace and defense applications by enabling sensitive detection of magnetic fields, electric currents, temperature, and stress. Research institutes and universities typically prioritize reproducible materials, pricing, and delivery timelines; industrial inspection and precision manufacturing customers emphasize system integration, reliability, and scalable supply; while aerospace and defense customers require stable sensing performance across wide temperature ranges and challenging electromagnetic environments, along with technical security and proven capability.
