The company’s mission, "Igniting the quantum era through ultimate materials, redefining the boundaries of perception," reflects its ambition to become the foundational innovation engine shaping a future defined by quantum sensing.

Core Technology: How NV Center Diamonds Work

ViQium’s core technology is built on nitrogen-vacancy (NV) centers in quantum diamond—a quantum defect system embedded within the diamond lattice that functions as an extremely small quantum sensor. The operating principle involves three steps: optical initialization using a green laser to prepare the NV center’s quantum state; microwave-based quantum manipulation to precisely control the spin state by adjusting frequency and duration; and optical readout, in which the NV center emits red fluorescence whose intensity varies with the final quantum state, allowing extraction of information about surrounding physical changes.

NV centers operate at room temperature with nanoscale sensing resolution, making them well suited for quantum sensing, biological imaging, and precision measurement without the need for cryogenic temperatures or complex vacuum systems. Their sensitivity to magnetic fields, temperature, and electric fields also positions NV centers as promising solid-state platforms for quantum information processing, including quantum computing and quantum networking.

Differentiated Advantages in Custom NV Diamond Fabrication

Advanced Color Center Engineering

ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This enables production of 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 leading international suppliers’ product series. Flexible customization is supported starting from a single piece, with pricing significantly lower than imported alternatives.

Integrated End-to-End Delivery

Rather than offering materials alone, ViQium’s technical team combines diamond material engineering with quantum measurement technologies. The company has built an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. Based on customer requirements, ViQium provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, along with long-term technical support throughout the customer’s R&D process.

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. Customers can tailor dimensions and NV center concentration to specific experimental needs. Standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days.

Product Portfolio for Diverse 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, complemented by Precision Instruments such as the Portable Magnetometer and NV Quantum Spin Spectrometer.

Single NV Diamond products, with T₂ of 300–600 μs and NV density from 10 to 10,000 units per 10⁴ μm², are ideal for quantum computing, networking, simulation, high-resolution quantum sensing, and single-molecule NMR. Ensemble NV Diamond, with NV density of 0.1–10 ppm, suits high-sensitivity precision sensing including current, magnetic field, and temperature sensing. Ultra-High-Density NV Diamond, with 10–45 ppm NV density, supports current, magnetic field, and temperature sensing as well as quantum memory and room-temperature solid-state masers. Shallow NV Diamond, with NV depths of 10–50 nm or 1–10 μm, applies to wide-field current imaging, wide-field magnetic imaging, and ultrafast nonlinear photonic sensing. Micro- and Nano-NV Diamond products serve super-resolution bioimaging, intracellular quantum sensing, miniaturized magnetometers and thermometers, and anti-counterfeiting applications. The NV Diamond Anvil, available with anvil faces from 20 μm to 300 μm, supports extreme high-pressure magnetism studies, geoscience and planetary research, and new-state-of-matter exploration. All products come with customer services including product customization and factory calibration and characterization data.

Industry Applications and Customer Solutions

ViQium’s NV center quantum diamond technology serves quantum precision measurement and advanced sensing across fundamental scientific research, industrial precision inspection, and extreme-environment detection. Applications span semiconductor inspection, power metrology, geological exploration, and aerospace and defense, enabling sensitive detection of weak physical parameters such as magnetic fields, electric currents, temperature, and stress.

For research institutes and universities, ViQium addresses challenges of unstable experimental results and insufficient reproducibility by offering a comprehensive NV Diamond Selection Guide alongside professional online consultation, categorizing products by application requirements such as magnetic field sensing, magnetic imaging, and temperature sensing. For industrial customers requiring small-batch customization and high-performance materials, ViQium combines flexible customization with in-house fabrication, tailoring crystal orientation, NV concentration, sample dimensions, and microstructure processing to specific needs.
