I'm really happy that this work was done by NIST! They are my favorite US federal government entity, even more than NASA. I worry about future funding for NIST now that there are so many science research budget cut-backs proposed, or maybe in effect.

I noticed that physical proximity was considered critical to the discovery:
"It is much less complicated than other state-of-the-art methods currently in use for producing ultra-enriched silicon such as that used for the International Avogadro project...There, enrichment requires...several facilities located in different countries, whereas with the NIST experiment 'we have literally microseconds from the point at which the separation happens to the point at which the deposition and growth has occurred,' Pomeroy explains."

I recall that NIST has several facilities. I wonder where this work was done. Was it mentioned?

Fantastic development in quantum computing.
