Quantum Applications

CIL offers a series of isotopically enriched quantum-grade (QG) gas and molecules for various quantum applications. Quantum magnetometers, quantum key distribution (QKD), and future innovations like quantum computers and quantum internet rely on color-centers diamonds. Frequently it is based on nitrogen-vacancy (NV) center diamonds or silicone-vacancy (SV) center diamonds. Regardless of the method used to synthesize these NV-centers diamonds, chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT), they required ultrahigh-purity starting material, highly enriched in 12C, and in the case of NV-center diamonds very low nitrogen content. 

Over the last decades, CIL has worked tirelessly with the best academic labs and diamond-industry leaders to provide a starting material compatible with their applications. After extensive testing in multiple academic labs, institutes, and industries in USA, Europe, Asia, and Australia, in 2022 CIL decided to assemble a separation column to provide a continuous source of highly enriched 12C used to synthetize 12C methane for quantum applications. Since early 2024 the separation and synthesis systems are fully functional. This quantum-grade material is commercialized under the name 12C Methane QG-Diamond™. CIL’s 12C methane QG-Diamond material offers 99.99% (2N5) 12C enrichment and 1 ppm or less of nitrogen content. The product is available from stock and can be ordered via our website and through our distributor network.

❛❛Isotopically engineered materials are essentials for quantum technologies. Availability of isotopically purified methane will enable growth of ultrapure diamond allowing to reach long coherence time of diamond spin qubits.❜❜
