I'm surprised there is no mention of D-Wave systems - the quantum computer that Google bought a while ago [1] and how/why they decided to build it themselves from scratch.

The D-Wave is not a quantum computer in the meaning that term usually has.

I'm under the impression that Google determined there was nothing quantum about it but is unable to speak up due to a forest of NDA's.

TLDR: DWave doesn't provide a speed-up over classical computers.

Maybe because IIRC D-Wave is still unproven technology.
