Isotopes for Quantum Applications

Isotopes for 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 nitrogen-vacancy center diamonds, also known as NV centers or color centers diamonds. Regardless of the method used to synthetize 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 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 industry in USA, Europe, Asia, and Australia, CIL has decided to offer a quantum-grade 12C methane: 12C Methane QG-alpha™.
CIL’s 12C methane QG-alpha material offers 99.99% (2N5) 12C enrichment and 3 ppm or less of nitrogen content.
Catalog number: CLM-392-ULN.
