Vicious Game of Battleship Currently Being Played in Quantum Computing Software World Between IBM and Google

Filed under: Uncategorized — rrtucci @ 4:48 pm

The competition between IBM and Google to hog the quantum computing limelight has been fairly intense this year. The following 2 high stakes games of Battleship are currently being played. Yikes. (Footnote: Google seems to have decided to marry the opaque, poorly designed software of ProjectQ so I lump them together below.)


Thanks son. You have crushed my spirit and now I will divorce your mom and leave you to her with no alimony.


  1. How about Liquid Microsoft quantum chemistry http://research.microsoft.com/apps/video/default.aspx?id=263611

  2. Hi Alex,
    Yes, Microsoft was promoting quantum chemistry before Google and IBM, mostly due to the marketing efforts of Krysta Snore and the scientific efforts of Matthias Troyer. At the time, Troyer was working one day a week for MS and the rest of the the week for ETH Zurich. But since then, Troyer has been hired full time by MS and has moved to Seattle. MS must have doubled his salary!

    But MS efforts in promoting quantum chemistry have faltered since then. Probably because LiquiD is closed source and MS is years away from producing a fully functional device whereas IBM and Google (and Lukin) already have one.

    After MS original efforts, Google came out with the paper 21 Dec 2015 mentioned above. The paper is funny because it includes Aspuru-Guzik as an author but not Troyer. The two are competitors. So Troyer must be persona non grata at Google for now, perhaps because of his association to MS, which Google dislikes, and because he was critical of DWave at the time when Neven supported it. Neven no longer supports it though, ever since he hired Martinis, who is very critical of DWave.

    It all sounds like a Dostoevsky novel , doesn’t it?

  3. I would say it sounds rather as mystery techno-thriller of Dan Brown. In Digital Fortress he wrote about quantum computer for cryptography and about many other interesting ideas (use virus to boil liquid He and destroy that), but even he did not guess to use that for quantum chemistry.
