ViQium Company Background: Quantum Diamond Innovation

Overview

ViQium Technologies Co., Ltd. is a company founded in 2025 and headquartered in Minhang District, Shanghai, China. Operating under the brand name ViQium, the company focuses on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. ViQium has built a global service network that supports research and industrial customers, guiding them from material selection through to successful application deployment.

Corporate Background and Founding Story

ViQium’s founding team is composed of experienced 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 extensive expertise spanning academic research and engineering practice.

Team Expertise and Technical Foundation

Through continuous work in material synthesis, defect engineering, and device integration, ViQium has established differentiated technological capabilities across the key stages of quantum material development. The team combines knowledge in quantum physics, materials science, and optical engineering with precision manufacturing experience, allowing it to bridge laboratory breakthroughs with industrial-scale implementation for global research institutions and industrial partners.

Strategic Positioning and Industry Insight

ViQium’s positioning is shaped by a clear understanding of the challenges facing the quantum technology sector. The company has identified several industry pain points that inform its strategic direction:

• High adoption barriers: Quantum technology adoption faces obstacles due to a lack of scalable fabrication and end-to-end capabilities among suppliers.
• Performance limitations: Conventional measurement approaches require a transition toward high-sensitivity, non-invasive sensing methods.
• Research inefficiency: Unstable experimental results and insufficient reproducibility in quantum materials continue to limit research progress.

In response, ViQium is committed to providing 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.

Mission, Vision, and Values

ViQium operates under the slogan “Sensing the Unseen.” Its mission is “Igniting the quantum era through ultimate materials, redefining the boundaries of perception,” while its vision is “To become the foundational innovation engine of the industry, shaping a future defined by quantum sensing.”

The company’s culture is guided by three defined principles:

1. The ViQium Spirit: Talent Attraction & Shared Vision — uniting global talent to enable deep focus and sustained discovery.
2. The Vi-Genesis Spirit: Source Innovation & Precision Excellence — pushing the limits of materials and systems at the source to accelerate deployment from prototype to real-world use.
3. The Diamond-Standard Spirit: Open Collaboration & Sustained Leadership — building proprietary technology through open collaboration while empowering the broader ecosystem.

Core Technical Capabilities

NV Center Technology Principles

ViQium’s core technology is based 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 a green laser to prepare the quantum state, microwave-based manipulation to control the NV center’s spin states, and optical readout through fluorescence analysis to extract 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.

Advanced Color Center Engineering

ViQium has independently established a production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. The company provides 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), achieving high ODMR contrast performance with key parameters comparable to international supplier. 

Integrated End-to-End Delivery

ViQium’s technical team combines expertise in diamond material engineering and quantum measurement technologies, establishing a service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. Based on customer requirements, the company provides material selection guidance, testing solutions, benchmarking, and experimental optimization recommendations.

Flexible Customization Platform

ViQium’s product portfolio includes high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders and single NV center diamonds. Standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days.

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, Nano-NV Diamond, NV Diamond Anvil, SiV Diamond, and Black Phosphorus. The company’s Precision Instruments line includes the Portable Magnetometer and NV Quantum Spin Spectrometer.

For example, Single NV Diamond products offer a T₂ of 300–600 μs (measured by Spin Echo) and are suited for quantum computing, networking, simulation, high-resolution quantum sensing, and single-molecule NMR. Ensemble NV Diamond products, with NV density between 0.1–10 ppm, are suited for high-sensitivity precision sensing applications such as current, magnetic field, and temperature sensing.

Target Industries and Customer Profiles

ViQium’s NV center quantum diamond technology serves quantum precision measurement and advanced sensing applications across fundamental scientific research, industrial precision inspection, and extreme-environment detection. The company supports applications including semiconductor inspection, power metrology, geological exploration, and aerospace & defense.

Three primary customer profiles are served: Research Institutes and Universities, which require high-quality, reproducible quantum materials and accessible experimental platforms; Advanced Industrial Inspection and Precision Manufacturing Companies, which need system integration, long-term reliability, and scalable supply capacity; and Aerospace and Defense Customers, which require highly sensitive detection and stable performance under wide temperature ranges and challenging electromagnetic environments.

Customer Challenges and Solutions

ViQium addresses common challenges faced by customers new to NV diamond technology. For customers uncertain about material selection, ViQium provides an NV Diamond Selection Guide along with online consultation, categorizing products by application requirements such as magnetic field sensing, magnetic imaging, and temperature sensing. For customers requiring small-batch customization, ViQium combines flexible production with in-house fabrication capabilities to tailor crystal orientation, NV concentration, and sample dimensions. For customers needing integrated experimental support, ViQium provides diamond samples, optical components, and system configuration guidance covering the full ODMR workflow, including optical alignment, signal acquisition, and magnetic field calibration.

Through its combination of materials expertise, device integration, and application-level support, ViQium positions itself as a resource for organizations working to advance quantum sensing research and industrial deployment.
