1. Quantum Grade Diamond
At the heart of quantum technology lies an extraordinary material—diamond, enhanced by engineered atomic defects. Nitrogen-vacancy (NV) centres in diamond serve as ultra-sensitive quantum sensors, enabling high-precision magnetometry, nanoscale imaging, and quantum communication. These unique properties position quantum Grade diamond at the forefront of quantum computing and sensing advancements.
Why Quantum Diamond?
Unlike traditional materials, diamond possess unmatched quantum coherence, durability, and stability, making them ideal for applications in:
Quantum computing – Harnessing spin properties for robust qubit performance.
Biological sensing – Enabling nanoscale imaging for medical breakthroughs.
Space and defence – Enhancing navigation with quantum-enhanced gyroscopes.
Secure communications – Quantum cryptography powered by diamond spin states.
Core Capabilities
Unrivalled Material Purity
“Start with ultra-pure single-crystal diamond substrates featuring nitrogen concentrations as low as <5 ppb – ideal for extending spin coherence times in NV⁻ centres, quantum memories, and magnetometry. Our material eliminates parasitic noise at the atomic level.”
Precision Nitrogen Doping (1 ppb → 200 ppm)
“Demand-specific nitrogen integration across 9 orders of magnitude:
Quantum Qubits: Optimize NV⁻ density with 1–100 ppb control
Sensing Arrays: Scale to 100–200 ppm for high-density spin ensembles
Buried Channels: Create subsurface layers with 10 nm depth resolution”
Advanced Structured Nitrogen Engineering
Buried Layers:
Subsurface NV⁻ networks shielded from surface noise (e.g., for waveguide-integrated sensors).
3D Gradient Stacks:
Multi-layer diamond with discrete nitrogen concentrations in each stratum – design heterostructures for quantum photonics or fault-tolerant systems.
-
Optical Grade
We synthesize ultra-pure, single-crystal diamond substrates with >80% broadband transparency (UV to IR) – delivering near-theoretical Optical Grade performance for systems where material limits define breakthrough potential.
Why Nitrogen Control Matters in Optical Diamond
At <5 ppb nitrogen:
Eliminates GR1 absorption centers (550–800 nm)
Prevents brown/gray tint in VIS spectrum
Reduces 270 nm UV absorption by 90% vs. commercial IIa diamond
Enables multi-kW laser operation without carbonization
