IBM vs. Google—Another Gun Fight at the OK Corral

IBM says: “Come out of there Google. Your ass is grass”

My friend Sol Warda prompted me in the comments to speak about a recent flood of news reports about a paper IBM published in the April 29th issue of Nature magazine. In the paper, IBM discusses their recent advances in error detection for their gate model quantum computer architecture based on Josephson junctions. Here is one of many such news reports.

I responded to Sol in the comments, but I am hereby promoting the response to a blog post. Here is what I said.

… I think it’s great news for QC software companies like Artiste-qb.net. Some of the quotes I’ve read from IBM spokesmen say something like “IBM will be the first to build a real quantum computer”. Now those are fighting words. Sounds to me like they are dissing annealers and challenging Google to a duel. It’s interesting to compare IBM’s gate model device to Martinis’ before he was convinced by Google to build an annealer. I think IBM may force Google to ask Martinis to build both a gate model device and an annealer at the same time. (They are sort of complementary anyways.) Big G sure has enough dough to do it, much more than Big Blue.

    Google responds: No it isn’t. I just checked.

  2. […] So while there's been plenty of news in the quantum computing hardware space to report, it is curious, and a sign of the times, that a recent Washington Post article on the matter opted to headline with a Quantum Computing Software company i.e. QxBranch. (Robert R. Tucci channeled the journalists at the WP when he wrote last week that the IBM news bodes well for software start-ups in this space). […]

  3. what do you mean “martinis was convinced by google to build an annealer”? that does not seem to relate to published info… he just contd on the current path he was on & was funded by google based on reports. also, the martinis lab hasnt published much on annealers have they? it would be nice to read an in depth analysis comparing/contrasting all the approaches somewhere.

  4. Vznvzn, both Martinis and Harmut Neven have been quoted by the media as saying that they intend to build an annealer with surface code quantum error correction (which is the type of error correction Martinis was working on before Google hired him). But why not build BOTH an annealer and a gate model, for almost the same price, since the staff and the technology would be essentially the same. I predict that this is what will happen, now that IBM has called Google out. If not, Google’s manliness will be called into question. It’s Freudian psychology 101.
