Quick! Someone form a Tech Article Sins (if one doesn't already exist... I think a Cracked video hinted at the existence of one) and count up the number of "Sins" this article racks up. They are doing very well at the "describe a limiting factor using vague words" game, similar to the pronoun game.
"break the rules"
Alright, so I've finally come across details that draw into question the article's assertion of an "optical switch using a single atom and accompanying circuitry", Some of us when thinking of an optical switch would consider some of the things they put in the "accompanying circuitry" column, port of the optical switch.
"Until recently, even I thought it was impossible for us to undercut this limit," said Professor Leuthold."
...Is not a follow-up to a quote by anyone on the team as to what limit he is referring to.
According to this article, all atoms are the same size, apparently.
There are a number of other sins, but I'm done with typing right now.
