"The inherent efficiency of the SILEX laser isotope separation technology potentially means that concentrations of Si-29 well below 100ppm could be achieved. The lower the concentration of Si-29, the better a silicon quantum processor will perform in terms of computational power, accuracy and reliability. "30 Si since this does not appear to cause problems for quantum computers (but it may inhibit the improved conductivity claimed for pure 28 Si). A feature of LIS is that it is very efficient at scavenging out (removing) low assays of one isotope - that's why it is so effective at upgrading low assay tails as the assay of an offending (for ZSSi) or sought isotope (for 235 U tails enrichment) - as the assay of this isotope increases then LIS becomes progressively less effective. In pure Silicon 28 Si represents 92.19% in natural abundance - LIS would not be an effective method for producing "isotropically pure" 28 Si directly - it would be far more effective to remove the minority isotopes 29 Si (4.7%) and 30 Si (3.1%). However for ZS Si it's unnecessary to remove the 30 Si since it doesn't create a problem for quantum computing but may do for low conductivity which is a feature of "isotropically pure " 28 Si. What I am arguing (and you appear incapable of understanding) that I cannot see where SLX claim to remove the 30 Si (this would cost them a lot more to do) for ZS Si since for their quantum computing application it's unnecessary to do sisotropcally pure " 28 Si for mixed 28 Si/30 S then you need to produce evidence that the 30 Si in the crystal matrix. Since the conductivity properties depend upon the crystal structure being completely regular it would appear that the presence of 30 Si would inhibit this regular crystal structure but I don't know and you haven't produced evidence to support your contention that 30 Si is immaterial to the low conductivity properties of isotropically pure 28 Si.30 Si (at additional cost which is of no benefit to quantum computing)30 Si has no impact on the low conductivity properties of isotropically pure 28 Si

Just for the record Zog!http://sqc.com.au/2019/12/16/zero-spin-silicon-project/ Launch of Silicon Enrichment Project for Quantum Computing Silex Systems Limited (SLX) and Silicon Quantum Computing Pty Limited (SQC) are pleased to announce the launch of a four year project (the Project) to develop a process for the commercial production of high-purity ‘Zero-Spin Silicon ’ using a variant of SILEX laser enrichment technology.high-purity ‘Zero-Spin Silicon’ ,Zero-Spin Silicon (ZS-Si) is a unique form of isotopically purified silicon https://en.wikipedia.org/wiki/Isotopically_pure_diamond isotopical pure diamond is a type of diamond that is composed entirely of one isotope of carbon
