what are they trying to say about the mixture of isotopes? |

The article says |

"Natural ytterbium is a mixture of seven stable isotopes, which altogether are present at concentrations of 3 parts per million." |

I'm not sure what that sentence is trying to say, but if ytterbium is a mixture of isotopes, "altogether" those isotopes must make up 100% of the substance, not 3ppm. |

Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Ytterbium. Additional text was taken directly from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.
Relevance to quantum computing
Two companies have stated publicly that ions of ytterbium form the active elements of the qubits in their quantum computer designs. This style of a qubit is called a trapped ion qubit, and quantum computers based on this design are commonly referred to as trapped ion quantum computers. This contrasts with the superconducting qubit designs contemplated by most other companies that are doing work in this area.
The two companies are Honeywell (e.g. this Honeywell press release) and IonQ (e.g. this IonQ press release).
It's worth mentioning because of the significant popular interest in quantum computing. I have always failed to live up to Wikipedia's quality standards when I make edits myself, though, so I've decided I have to leave the edit itself to others.
dodecaboride surface conducts
Could mention Borides eg dodecaboride [1] - Rod57 (talk) 12:40, 16 September 2018 (UTC)
