QuantumCore™ Ultra Diamond

Ultra-Pure Electronic-Grade Single-Crystal CVD Diamond for Quantum and NV-Center Research

QuantumCore™ Ultra is an ultra-high-purity, electronic-grade single-crystal CVD diamond platform designed for applications requiring an exceptionally low nitrogen background and precise control over defect formation.

With nitrogen concentrations below approximately 10 ppb, QuantumCore™ Ultra provides a substantially cleaner diamond lattice than conventional optical-grade or nitrogen-rich NV diamond. The reduced nitrogen background makes it particularly attractive for researchers who want to create and control their own NV-center populations through irradiation, implantation, annealing, or related defect-engineering processes.

Unlike NVCore™ Ensemble and NVCore™ Premium, QuantumCore™ Ultra is not supplied as a high-density ensemble-NV material. Instead, it serves as a low-defect host crystal in which researchers can intentionally introduce vacancies and engineer the resulting NV-center concentration, depth distribution, and defect environment.

This low-background approach is especially valuable for experiments where unwanted paramagnetic impurities can limit spin coherence, ODMR linewidth, or defect reproducibility.

QuantumCore™ Ultra is particularly suited for: Electronics, ultra pure diamond studies, and photonics. The represents the purest electronic grade diamond available in the world. 

Because the starting nitrogen concentration is approximately three orders of magnitude lower than ppm-level optical-grade diamond, QuantumCore™ Ultra provides researchers with substantially greater control over the final NV population and surrounding spin environment (by external ways irradiation, pressure etc.).

Product selection guideline

For applications requiring pre-existing ensemble NV centers, NVCore™ Ensemble and NVCore™ Premium provide ready-to-use NV-containing diamond platforms. For general optical and spectroscopy applications, OptiCore™ Diamond offers a cost-effective optical-grade solution. QuantumCore™ Ultra is intended for researchers who is in electronics field or want to introduce NV centers or other defects themselves, starting from an ultra-pure, low-impurity diamond host for controlled defect engineering and quantum sensing studies.
