# When and where was the first use of the term Chimera?

This is along the same lines as the earlier question: When was the first use of the word Entanglement?

I was surprised to discover that when searching for "chimera" in both of Vicky Choi's minor-embedding papers:
https://arxiv.org/abs/0804.4884,
https://arxiv.org/abs/1001.3116,
no results came up!

This means that finding the first "chimera" paper is harder than I imagined and I don't know where to look anymore. When and where can I find the first use of the term?

The earliest non-internal reference I can find is in NIPS 2009 from a Google/D-Wave effort1. You'll notice that the two Choi papers, in addition to not using the term "Chimera", do not describe a Chimera graph (and note that the name comes from D-Wave, not from graph theory).

For a good early reference on Chimera, I recommend Bunyk et al., 20141 , which describes graph theoretical and other practical considerations related to the architecture.
