This breakthrough utilizes ORNL's Electromagnetic Isotope Separation (EMIS) technology to produce ultra-pure silicon and germanium, reducing noise-inducing isotopes by 100× compared to commercial sources. By restoring domestic capability for these specific materials since the last large-scale enrichment facilities closed in 1998, this advancement directly addresses a critical bottleneck limiting quantum computer stability and scalability.
ORNL develops 100× quieter isotopes for domestic quantum computing
Oak Ridge National Laboratory (ORNL) achieved a breakthrough, producing silane & germane at least 100x more depleted of noise-inducing isotopes than current commercial sources.
Oak Ridge National Laboratory and Pacific Northwest National Laboratory have achieved a breakthrough in stable isotope enrichment, producing silane and germane with at least 100 times less of the noise-inducing contaminants found in any commercially available material worldwide. The collaborative effort reduces concentrations of isotopes like Ge-73 and Si-29 to below 1 part per million, with Si-28 purity reaching 99.9999% in silane, a critical advancement for quantum computing stability. “This advancement has the potential to increase the operability of quantum computers and will help the U.S. be a leader in the quantum technology…
