The Wicked Witch of the West, Krysta Svore

Filed under: Uncategorized — rrtucci @ 10:29 pm

2 years ago, I pointed out that Krysta Svore often behaves unethically.



What devious misdeeds has she been up to lately? Well, as of today, April 3, 2018, she has:

  • a whopping 24 software patent applications (14 of those are on quantum computing). See USPTO search results here Check it out. Pretty soon, you won’t be able to do some pretty trivial operations in quantum AI without paying Microsoft.
  • a whopping 15 granted software patents (8 of those are on quantum computing). See USPTO search results here.

In a previous blog post, I compared in detail artiste-qb.net’s quantum computing language Qubiter to Microsoft’s quantum computing language Q#. Q# is a Rube Goldberg machine language that doesn’t even look like what everyone else calls quantum computing. It looks very different and is much more convoluted than its major competitors (IBM qasm, Rigetti PyQuil, Google’s ProjectQ, and the best of its class, Qubiter). Why would anyone want to learn another crappy Microsoft language, when, instead, they can use Python, like all the competitors just mentioned are doing? The choice of Python for this task is not a fluke, there are some very good reasons why MS’s qc competitors are using Python. Python is well designed, powerful, beautiful, and it has a richer collection of science-math-engineering supporting apps (its “ecosystem”), most of which are free and open source, than any other current language.

So why does Q# suck so badly? Is this just a consequence of Microsoft’s penchant to monopolize markets and “bind for life” its customers to its products, or is there an aggravating factor? Yes there is an aggravating factor. It’s that one of the main architects and promoters of Q# is the Wicked Witch of the West, Krysta Svore.

In a scary nightmare that I keep having, Krysta yells the following curse to all qc fans:

“From the pits of Microsoft Hell, I curse thee, may you, and your children, and your children’s children, and their little dogs too, be forced to use Q# for the rest of their careers. ha, ha, ha, I made it extra convoluted to enjoy your pain.”

I predict that Q# will end up being as popular as the Zune. Will Microsoft rightly blame Krysta for the abysmal failure of this product, or will they blame Dave Wecker instead? Whoever is blamed will probably end up in Microsoft-Siberia, vanished from quantum computing land, bug testing new features for Microsoft-Office.

  1. While your were into witch-hunting, this came about so better take a look – they might be interested in cooperation.

  2. Thanks for the link, Theo.
    Another very interesting development is that Aspuru-Guzik, prof at Harvard for almost a decade and very well known for his work using qc to do chemistry, is moving to the U of Toronto in July, and has started a new company called Zapata which has obtained $5.4M seed funding!! Zapata is one of the startups mentioned in your link.

    I’m debating on whether to write a blog post about your link and about the Aspuru Zapata news. This is all very good news for us. Our business plan has nothing to do with quantum chemistry, so there is very little overlap between Zapata and us. Zapata will attract qc talent to Toronto , artiste-qb.net’s home town. Such a high valuation for Zapata makes Artiste a basement bargain.

  3. Excellent! Meanwhile I am doing progress in something unexpected – at least to me. I figured that it is possible to apply that arithmetization technique I published last year into the whole set of Temperley-Lieb algebras. It all boils down to the older work by Abramsky that recently culminated in this very nice book about diagrammatic calculus for QC by Coecke.

    I strongly suggest you take a look at the contents. How to say this, “There are more in the Earth and the Sky…”

  4. I don’t know category theory or have studied in depth the work of Coecke but it always seemed to me that it is closely related to bayesian networks, except bayesian networks are better 😎😎.

  5. Sure, but wouldn It be nice if we could also put them into analog implementations using OFDM and radar techniques?
    Oh, and there is this OS from the future that I dont expect to see by Microsoft any time soon…pure Ambient Immersive Computing!
