It isn't that clear but Scott Aaronson did make an admission in this article that I do not believe he has made before -- he admitted the D-Wave compute exhibited quantum effects:
"As far as I’m concerned, this completely nails down the case for computationally-relevant collective quantum tunneling in the D-Wave machine"
I believe many of his previous blog posts had argued strongly that there was no proof of any quantum effects in D-Wave computers, but I could be misremembering.
- dvanduzer 11y agoScott Aaronson's entire professional life is essentially to distinguish what could and couldn't be a quantum effect in computation. So yes, your memory is accurate that his previous blog posts argue strongly that nothing D-Wave computers had done proved any quantum effects. His acknowledgement that they've achieved quantum computation is a compliment to their engineering prowess. But he is complimenting new engineering results.
- shoyer 11y agoIt's been clear that the D-Wave machine is exhibiting quantum effects for several years now. See Aaronson's blog (http://www.scottaaronson.com/blog/?p=1400 http://www.scottaaronson.com/blog/?p=1400) and this Nature Communications paper (http://www.nature.com/ncomms/journal/v4/n5/abs/ncomms2920.html http://www.nature.com/ncomms/journal/v4/n5/abs/ncomms2920.ht...). On the other hand, it's still not clear that this results in computationally relevant speedups. In my mind, this is not much of a shift in the status quo.
- lmm 11y agoIt's not an "admission" - there wasn't proof before (Aaronson never claimed that the effects weren't computationally relevant, only that they hadn't been proven to be) and now there is.
