Quantum Bayesian Networks

The Canadian Starship and the Dutch Campervan

On Dec. 3, 2015, three mayor Dutch universities opened a new institute called QuSoft that, according to the press release, will be dedicated exclusively to writing quantum computing software. QuSoft is being billed as the first academic institute to be dedicated in that manner, and I tend to agree. As far as I know, no other nation has a similar institute.

It seems clear that QuSoft and its partner Dutch institute, QuTech, which does hardware instead of software, have intentions of eventually converting into private corporations after government funding has made them profitable. I reported earlier on QuTech in my previous blog post entitled “The Dutch Stallion and the Canadian Donkey”. Thus, it appears that the QuSoft-QuTech-Intel-Microsoft juggernaut will become more industrial and less academic as time goes on.

Meanwhile, IQC of the Univ. of Waterloo, Canada, founded 13 years ago (2002), has spent more than $150M to become the world’s leading powerhouse in NMR quantum computing and quantum cryptography, both known to be dead end streets since day one. They have also produced a computer game called QuantumCats, a knockoff of Angry Birds. Playing QuantumCats for 100 hours teaches less quantum mechanics than reading Wikipedia articles about QM for 15 minutes. Also, a Canadian Univ. (Dalhousie) used American defense funding (from IARPA) to write a QC programming environment called Quipper. The only problem is that Quipper is written in Haskell, a programming language so cryptic that almost nobody uses it in industry.

But despair not, Justin Bieber compatriots. I live in the US, but the company that I work for, artiste-qb.net, is incorporated in Canada. Oh Canada, we salute thee!

small-dragonflyartiste-qb.net is a software company led by scientist programmers with close ties to industry, not by academics that program in Haskell. Our “Quantum Fog on GitHub” project is open-source under the BSD license and coded in Python. We also have 12 QC software patents (6 granted and 6 pending). QuSoft starts off with zero patents.

Time will tell, but right now, QuSoft is looking pretty frumpy compared to my company. QuSoft reminds me of a Dutch campervan, of the type that plagues French, German and Spanish camping sites every summer. If you are not familiar with this natural phenomenon, comparable to a Monarch butterfly migration, here is a description from the National Geographic (sort of). On the other hand, artiste-qb.net reminds me of a starship, an analogy which I made before in my previous blog post entitled: “Houston, Tranquility Base here, the Dragonfly has landed”. artiste-qb.net will reach for the stars, and QuSoft will reach for the cows.

The TonkePR4, deluxe Dutch campervan. Now all my Dutch readers will want to own one.

  1. Hello Dr. Tucci: Here is some off-topic news from Google about their D-Wave machine:


    And here is their Arxiv paper:


    Thanks and have a good day.

  2. Thanks Sol. Already knew about it from Twitter. I’ve been using Twitter for a couple of months and I like it much more than I thought I would. I like the rule that, unlike blogs, you can reply to people’s advertisements and they can’t remove or censor your replies but you can remove them yourself if you repent 😿 That rule is sheer genius. I still love blogging though; 140 characters is not enough to make fun of humanity.

  3. Hi Bob: Here is an article about AI that maybe near and dear to your heart, because it uses ” Bayesian program learning framework, or BPL” to do its tricks. Enjoy and have a good day.

  4. Thanks Sol. And of course, your country, Canada, is even more distinguished in Bayesian networks than MIT. Geoffrey Hinton comes from the U. of Toronto, and what is nowadays called Deep Learning is a special case of Bayesian networks (also called Belief Networks)
