Questions tagged [chimera]

For questions about the D-Wave Chimera architecture. The increase in qubit count for the D-Wave Two was accomplished by tiling qubit pattern of the D-Wave One. This pattern, named Chimera by D-Wave Systems, has limited connectivity such that a given qubit can only interact with at most six other qubits. (Wikipedia) Consider using the [dwave] tag with this.

Why did D-Wave choose the Chimera graph the way they did?

D-Wave makes use of a $(n,k=4)$-Chimera structured graph in their computers. Meaning a $n\times n$ grid of unit cells, with each unit cell consisting of a complete bipartite graph on $2k=8$ nodes ($4$ for each side), also called $K_{4,4}$. Why did…

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,…
