Quantum Fog Comes Out of the Closet

Filed under: Uncategorized — rrtucci @ 4:06 am

Quantum Fog, my old Mac application for doing calculations with quantum Bayesian networks, is now open-source (it’s finally out of the closet). Check it out at GitHub.

Quantum Fog was originally written in C++, but we plan to rewrite most of it in Python

By the way, I highly recommend the GitHub website if you need to collaborate with a group of people on the writing of a computer app or a website or an arXiv paper, or many other possibilities. I use GitHub in conjunction with a Windows app called TortoiseGit, which I also love and highly recommend.

A Quantum Computer is the Ultimate Group Theory Box

Filed under: Uncategorized — rrtucci @ 4:31 pm

In previous blog posts, I mentioned my recent interest in using group theory in quantum computing algorithms. See for example,

Group Theory and quantum mechanics are like co-joined twins. It’s hard to tell where one begins and the other ends. So I was somewhat ashamed that I had used so little Group Theory in my quantum computing programming. I’ve been trying to overcome that weakness of mine in the last year and I’m beginning to see the results. I am all stoked up today because this week I filed my second US patent applying Group Theory (GT) to quantum computing (QC). This means our company http://www.artiste-q.net now has 12 US patents on QC programming (6 granted, 6 pending)

I can’t say much about my 2 QC-GT patents for now because loose lips sink ships, but I did prepare some pictures to convey my enthusiasm for QC-GT. In a previous blog post, I waxed poetic about the connections between the movie “2001, A Space Odyssey” and quantum computing. This time, I adapted a “2001- a Space Odyssey” T-shirt that I think is really cool so that the black monolith has some hieroglyphics on it dealing with GT. Ta-tan, here are my pictures:
Very little of the art work in these two images was originally created by me. My images were mostly based on the following two previous images

  1. T-shirt image from this page of the website of tshirtbordello.com.
  2. Image from Wikipedia article on Point Groups in Three Dimensions. There are 7 infinite sequences of point groups in 3 dimensions with cylindrical (uniaxial) symmetry. The groups in each sequence are indexed by n. The n-th group has n-fold rotational symmetry about the axis of symmetry. This figure from Wikipedia shows those 7 sequences for n=6.

Google Open-sources TensorFlow (A Fakesian Networks Software Library). Microsoft, Tear Down This Infer.NET Wall

Filed under: Uncategorized — rrtucci @ 5:21 pm

Check out

On Nov. 10, Google announced to much fanfare that it was open-sourcing TensorFlow, their software library for “Large-Scale Machine Learning on Heterogeneous Distributed Systems”. At this point in time, I know very little about TensorFlow, but I can already see that it is not very Bayesian Networky. Me being such an avid B Net fan, I can’t deny that I was a little disappointed by how little B net stuff it contains. To me, TensorFlow is Fakesian Networks instead of Bayesian Networks :)

In my opinion, TensorFlow has VERY LITTLE in common, except for the name, with what quantum information theorists call “quantum tensor networks”, although I’m sure that some sleazy, opportunistic physicists and science journalists will claim that the two are co-joined twins. Unlike the classical, mostly deterministic, highly distributed calculations that TensorFlow performs, quantum computers have to deal mostly with quantum probabilistic instead of deterministic calculations, and distributed computing for QCs would be very different than its classical counterpart. I think when dealing with probabilistic calculations, either on a classical or quantum computer, Classical Bnets and Quantum Bnets are the most natural and productive framework/strategy, as I’ve explained before.

Despite TensorFlow being Fakesian Networks, I welcome Google’s move to open TensorFlow, because it certainly raises the level of visibility, cooperation, competition and tension/suspense in the AI arena. For example, I’m sure that right about now Microsoft is facing a lot of pressure to respond in kind to the news about TensorFlow. So what does Microsoft use instead of TensorFlow to do its Bing AI? Is it Infer.net? Whatever it is, will MS have to open source part of its Bing AI, to keep up with the Joneses and the Kardashians?

I like Infer.net. It looks much more Bayesian Networky to me than TensorFlow does. Unfortunately, so far MS has only released to the public infer.net’s binary and API, and it has forbidden non MS people from using infer.net for commercial purposes.

Told you so UPDATE1: Ta-tan, Nostradamucci’s predictions have turned into reality again. Nov 12, just 2 days after Google released TensorFlow, Microsoft announces the open-sourcing of DMTK (Distributed Machine Learning ToolKit). And of course, Facebook was the first, with its open-sourcing of Torch enhancements on Jan 16 of this year.

UPDATE2: Related news. After UPDATE1, I learned that IBM has also been busy open-sourcing distributed AI software. It has recently open-sourced SystemML (ML=Machine Learning), a small part of its Watson software. The GitHub repository of SystemML was started on Aug 17, 2015. According to this press article, circa Nov 23, 2015, SystemML was accepted into the Apache incubator (a preliminary step to being declared a saint, where sainthood means you have performed 2 miracles and you are declared officially integrated and compatible with the Apache libraries, especially Spark, which SystemML will rely heavily upon.)

Quantum Gravity Photo

Filed under: Uncategorized — rrtucci @ 4:45 pm

This POV (Point of View) photo reminds me of quantum gravity (in a poetic sense). I found it in the Blog of Francesco Mugnai.

It’s beginning to look like Quantum Computing will elucidate Quantum Gravity, both by allowing us to perform simulations of theories of it (as Feynman predicted) and by enriching the theory itself (for instance, quantum information, error correction and complexity theory inspired elucidations of the black hole information paradox and Maldacena’s gauge/gravity duality).

Our company http://www.artiste-qb.net has a unique POV regarding quantum computing, that of quantum bayesian networks.

Snow White Bayesian Network For a Collection of Sets

Filed under: Uncategorized — rrtucci @ 5:21 pm

CB net= Classical Bayesian Network
DAG= directed acyclic graph

In supervised learning, you are given the graph (aka structure) of a CB net, and some data, and you evaluate the node probability matrices from the data. In unsupervised learning, you are given only data, and you are expected to come up with the structure and node probability matrices of the CB net from that data. Nowadays there are computer programs that do both supervised and unsupervised learning of a CB net on classical computers. I believe a quantum computer can do unsupervised learning of a CB net at least quadratically faster (due to Grover’s algo) than a classical computer. In fact, I have a patent for doing unsupervised learning of a CB net on a gate model QC. (The Quail group at NASA has proposed doing this also with a D-Wave annealer QC).

And yet, many of the examples of CB nets that show up in the literature (See, for example, the wonderful work of Andrew Gelman) were obtained “by hand”—their structure was derived without the help of a computer, arrived at partly by logic and partly by hunch. The quality and value of these CB net models depends on how well they fit the data.

So can I provide some guidance on how to find the structure of a CB net by hand? I don’t know how the experts do it, but I’ll tell you how I think about it.

There is one situation that I like to call the Snow White CB net (I call it Snow White because it’s the fairest CB net of them all). It concerns finding a CB net that connects a collection of sets.

Snow White DAG
Suppose you have n sets A_1, A_2, \ldots A_n which are not necessarily mutually disjoint.

  1. Merge all sets that are equal into a single set.
  2. Write an undirected line connecting those pairs of sets that overlap (but not if they don’t overlap).
  3. If A_i \subset A_j, then replace the undirected line joining them by an arrow pointing from A_i to A_j. Thus

    A_i \subset A_j
    A_i \rightarrow A_j
    x\in A_i \implies x\in A_j

    all mean the same thing.

  4. If A_i and A_j overlap, but neither is a proper subset of the other, then replace the undirected line between A_i and A_j by

    A_i \leftarrow A_i\cap A_j \rightarrow A_j

  5. Go back to step 1. Exit loop when last two repetitions yield the same DAG.

At the end, you will have a DAG in which the arrows all indicate a subset relationship. Also, by the end, all the root nodes (the ones with no incomming, only outgoing arrows) will be mutually disjoint sets. This is all very trivial and I’m sure a lot of people have come up with the Snow White DAG on their own. I just mention it in case you haven’t yet.

PS. In the above convention, a typical operating system with folders is represented by a tree, with the arrows pointing away from the multiple innermost folders towards the single outermost folder. The outermost folder is often called the root directory in operating system parlance, but here I am calling the innermost folders the root nodes.

Caltech Abhors MOOCs

Filed under: Uncategorized — rrtucci @ 4:12 am

I’ve expressed my very favorable opinion of MOOCs many times before in this blog.

Today I visited the Coursera and EdX websites and learned that they are currently offering 1,465 courses and 233 courses, respectively. So MOOCs are alive and well, at least today.

I was curious to see how many MOOCs Caltech is currently offering so I went to a website called “MOOC List”. According to that site, the grand total of Caltech MOOCs since the beginning of time is 5. 😸 Let me copy and paste the full list here:

  1. Machine Learning (Caltech) Self Paced
  2. The Science of the Solar System (Coursera) Mar 30th 2015
  3. Galaxies and Cosmology (Coursera) Jan 6th 2015
  4. Drugs and the Brain (Coursera) Jan 4th 2014
  5. Principles of Economics for Scientists (Early 2013) Jan 7th 2013

Looks like the Caltech Evil Empire abhors MOOCs…


In a small galaxy called Caltech far, far away from Stanford University, Darth Vader Preskill is informed by Emperor Palpatine that the two co-founders of Coursera, Daphne Koller (aka Princess Leia) and Andy Ng (aka Luke Skywalker), are his offsprings, and that they are threatening the Empire of traditional Universities that Lord Vader has sworn to defend.

The following is a quote from the movie “The Empire Strikes Back”, with some minor modifications. My omissions from the quote are crossed out. My additions to the quote are placed in parenthesis.

Darth Vader Preskill: [kneeling before Emperor Palpatine’s hologram] What is thy bidding, my master?

Emperor Palpatine: There is a great disturbance in the (Educational) Force.

Darth Vader Preskill: I have felt it.

Palpatine: We have a new enemy. The young (Coursera) Rebel(s) who destroyed the Death Star. I have no doubt this boy (and girl are) is the offspring of Anakin Skywalker.

Darth Vader Preskill: How is that possible?

Palpatine: Search your feelings, Lord Vader. You will know it to be true. He(They) could destroy us.

Darth Vader Preskill: He’s just a boy. (They are just children). Obi-Wan can no longer help him (them).

Palpatine: The (Educational) Force is strong with him(them). The son (and daughter) of Skywalker must not become a Jedi.(MOOC Jedis).

Darth Vader Preskill: If he (they) could be turned, he(they) would become a powerful ally.(powerful allies)

Palpatine: [intrigued] Yes… He (They) would be a great asset. Can it be done?

Darth Vader Preskill: He (They) will join us or die, master.

Teaching Quantum Mechanics to Children, the Caltech and Waterloo Univ. Method

Filed under: Uncategorized — rrtucci @ 7:29 pm

I’ve heard some uncouth people, naysayers and sour grapes most of them, voice the extreme, malicious opinion that video games are junk food for the mind.

And what about the recent video games qCraft (by Caltech) and QuantumCats (by University of Waterloo in Canada) which promise to teach quantum mechanics to children? To the naysayers, those video games are poison too, quantum junk food, a way of wasting, piddling away the precious, jam-packed, fleeting years of youth.

It occurred to me that such opinions could be put to the test scientifically. So I was very happy when, while poring over the Lancet, a journal which I read faithful every Sunday, I came across the following article about a study conducted by the Mayo Clinic on this very subject.

Clinical Study of the Effects on Children of Playing Video Games qCraft and QuantumCats
by Mayo Clinic, Oct 1, 2015



We conducted a 1 year study on a group of 20 school children, ages 10 to 18, who showed an early interest in math and science.

10 of the children were our control group A, and 10 were our video gamers group X.

The children from group A were given classroom courses by really good high school teachers in Algebra, Geometry, Calculus, Biology, Physics, Chemistry. They were encouraged to consult Kahn Academy, Wikipedia articles, take MOOC courses and read books on science and math. Those yearning for hands on experience were encouraged to join a Ham radio club or local Hackers club and build their own electrical devices or else join an open source programmer’s group and start writing computer code at an early age.

Group A children were also encouraged to do some physical activity by going to a court or gym and practicing a sport, and joining a youth sport team if possible. Bicycling, swimming, jogging, dancing, etc. were all encouraged

The children in Group X were told that before taking a math or science course, it would be better if they first learned the basics of Science by playing some video games. By practicing how to build a quantum computer out of imaginary Lego blocks or throwing quantum cats with a catapult, they could learn the basics of quantum mechanics first, and then, if after a year or two of that they showed any promise, they would be permitted to take courses in science and math, and consult Kahn Academy, Wikipedia and all those other old-fashioned, boring resources.

If the children from Group X wanted to do some physical activity by playing a particular sport, they were told that it would be better if they first learned the basics by playing a video game about that sport. If after a year or two of that they showed any promise, they would be taken to a court or gym to learn the physical part of the sport.

We found that 95% of the children from group A went to good colleges. 5% never made it to college because they had already started their own high-tech businesses in high school and saw no need to go to college.

We found that 95% of the children from Group X never went to college, because they were recruited by the Army right out of high school as drone plane operators. 5% did make it to college, mostly MIT, where they eventually became professors.

The figure above shows a typical child from Group X, after 0,1,2,3,4 months into the clinical study. His cranial capacity diminished by 15cc after 4 months but we were told by Caltech and Waterloo that if we had run the study for a longer period of time, we would have seen that cranial capacity reaches a minimum after 4 months and then begins to increase. They also pointed out that our study was flawed in methodology and too low in number of children to be statistically significant.

Donald Trump to Invest $200M in Quantum Computing

Filed under: Uncategorized — rrtucci @ 9:26 pm

Political activity associated with the USA 2016 presidential election has been pretty bizarre lately. Currently, the top candidate for the Republican Party, leading by about 10 percentage points, is Donald Trump, a guy who wears a fluffy, dead rat on his head, a 69 year old senior citizen who doesn’t think very highly of women or Mexicans except when they are cleaning his home and tending his lawn, a real estate, hotel, casino and golf course mogul plus an awful TV host supposedly worth $4B.

According to Wikipedia, NBC and Trump jointly owned the Miss Universe beauty pageant from 2002 to 2015. The Donald, in his speech announcing his candidacy for the 2016 presidential election, said most Mexican immigrants are criminals and rapists. Disturbed by those statements, NBC pulled out of the partnership, and The Donald was forced to sell the company shortly thereafter, in Sept 2015.

But now The Donald has announced that he is starting a new beauty pageant called Quantum Miss Multiple Universes, which is going to obliterate the old, classical Miss Universe pageant. It’s going to be exponentially better. His initial investment in QMMU is $200M, just a fraction of what he has spent already in the 2016 presidential election. Mr. Trump said at a press conference:

“The talent competition for the Miss Universe 2002 pageant was won by Scott Aaronson with a talk on Quantum Complexity Theory. Ever since that talk, I’ve been a firm believer that quantum computers are possible. This beauty pageant will hasten the construction of quantum computers. Another great source of inspiration for this beauty pageant is #quantumwoman on Twitter”

Below is a photo of Miss Universe 2002, Scott Aaronson. (Beauty standards have changed since then.)


As a Miss Universe winner, Scott has had a grueling career traveling to all the countries shown below as an ambassador of good will.

Of course, instead of vacationing in those countries, Scott could have used any of the numerous resources available nowadays to give a talk (Skype, Google Hangouts, YouTube video, fax, email with attached pdf, blogs, website, arXiv, HAL, an old fashioned but quite effective telephone teleconference, ResearchGate…) But nothing beats the homeliness of delivering in person the same talk that he always gives, delivered to a huge, enthusiastic audience of fawning admirers that understand about 1% of what he is saying.

China Mulling Over List of Presents to Itself For Next Christmas

Filed under: Uncategorized — rrtucci @ 9:49 pm

Check out

Visions of Future Physics, by Natalie Wolchover
(Quanta Mag., Sept, 2015)

The article is about renowned Princeton Univ. Prof. Nima Arkani-Hamed. In particular, the article describes his fascinating personal history and his quest to convince the world, starting with China, to build a 100-TeV successor to CERN’s 10-TeV Large Hadron Collider. (successor just 10 times higher in energy than the LHC)

It’s a well written and interesting article with some slight relevance, from my biased point of view, to quantum computing. As I recently reported in this blog, Alibaba and the Chinese government recently announced that they intend to build a QC lab in Shanghai

Excerpts from article

Now it is decision time. The Chinese government will release its five-year budgetary plan by the end of the year, revealing whether it plans to invest in research and development for the collider project.

To Arkani-Hamed, the Chinese collider campaign feels like pushing an open door. “When you think about it more, it’s just perfect,” he said, sipping Coke Zero on his office couch. “It would be great for physics; it would be great for China. They’re looking for something where they can just be the best in the world.” He continued, “There are very few things in life where what you want to do for idealistic reasons and what someone else wants to do for Machiavellian reasons are identical. And when that happens, you should just do it. You should just do it!”

It occurred to me that the same argument used above by Nina to sell the 100-TeV collider could be used to sell quantum computers and even aircraft carriers to China. (The following table is very approximate and speculative. This being a QC blog, you know where my loyalty lies)

Quest Final Cost time to build it scientific benefits industrial benefits military benefits
100 TeV collider $10B 25 yrs. Yes Small (Magnets)
Kitaev Quantum Computer $200M 10 yrs. Yes Yes Yes
aircraft carrier $5-10B 5 yrs. Small Yes

More on China’s 13th five year plan (2016-2020). First draft expected Oct 2015, final draft expected March 2016. It’s time to lobby your Chinese “congressman”

Universal Studios in Final Negotiations to Buy Caltech

Filed under: Uncategorized — rrtucci @ 10:31 pm

Caltech university is about a 30 minute drive from Universal Studios in Los Angeles. And ever since Richard Feynman and Murray Gell-mann left it, Caltech has decided to double its activities in the entertainment industry. So it came as no surprise to us when we heard that Universal Studios was in the final stages of negotiations with John Preskill to buy Caltech from him. We here at TMZ immediately moved into action and sent one of our ersatz reporters to query a top executive at Universal about the matter. Here is what the executive had to say:

We had to move quickly before Disney grabbed them. This science bunkum stuff is a very hot commodity right now. When we heard that Disney was considering revamping their unbearably sweet pavilion “It’s a small world” and replacing it by a pavilion called “It’s a Many Worlds”, featuring a sing-along led by Sean Carroll, we moved quickly to preempt them. That Sean Carroll sing-along, we just had to have it for Universal Studios!

Caltech is already quite a powerhouse in the entertainment field:

They have their own fashion designer Spiros Michalakis that produces the manly Spiros Hoodie.

In the addictive games for young vulnerable children department, they produce their own modification of MineCraft called QCraft.

In the advertising department, they are awesome too. Their Twitter accounts @preskill and @QIM_Caltech are manned 24/7 by John Preskill, and, rarely, by someone else. Also they hired their own in-house cartoonist (phdcomics.com) to produce some primo YouTube videos that publicize John’s institute. I don’t think any quantum institute pays more for publicity except maybe IQC in Waterloo.

In the book publishing industry, they have the lucrative Feynman memorabilia franchise, and they are grooming the budding Kitaev franchise as we speak.

In the intentional science fiction field, they are pulling in top dollar doing consulting for the sci fi movie industry. All the science bunkum in the movies Interstellar and Ant-Man is due to them. And of course, they also excel in the unintentional science fiction field.

It’s true that they failed badly, $500M down the drain, with the LIGO experiment, but Universal Studios is exhilarated that they failed. Universal is planning to convert LIGO into the most awesome roller-coaster ride ever. Imagine it. We are going to insert into that linear pipe a magnetically levitated, 2 passenger capsule sled. The inside of the pipe will be in near vacuum so that sled is going to reach a speed of a few Machs. We plan to brake the ride with some humongous bungee cords.

The Caltech amusement park is going to be serviced entirely by postdocs. It’s true, the current crop of Caltech postdocs is subpar in terms of the required intelligence and good looks (look at their embarrassing blog posts!), but we plan to replace them gradually by some beautiful and brainier Valley girls in roller skates and mini-skirts. We might also hire some of the hotter looking babes in #quantumwoman Thank God those guys are so thoughtful to show pictures of them. That is so important when hiring women scientists.

LIGO amusement ride, coming soon to Universal Studios. Eat your heart out, Disney and Las Vegas.

Quantum Bayesian Networks for Quantum Field Theories And Beyond

Filed under: Uncategorized — rrtucci @ 8:33 pm

I often describe QB nets (Quantum Bayesian Networks) as being a graphical method for representing any quantum density matrix (see, for example, http://arxiv.org/abs/1204.1550 for more info on why I say that). Because of this description of mine, some might be led to believe that QB nets do not shed much additional light onto theories that stick to pure states for the most part.

In most of my papers, I use QB nets with nodes that have a finite number of states. Once again, this might lead some to believe that QB nets do not apply to continuum theories, yet most theories in High Energy Physics are continuum theories

I wanted to write a brief blog post to emphasize that QB nets can also be useful for both pure state and continuum theories.

In fact, the same dichotomy already exists for CB nets (Classical Bayesian nets). Judea Pearl is a very famous researcher that likes his CB nets with nodes that have a finite number of states, and Andrew Gelman is a very famous reseacher that likes his CB nets with nodes that have a continuum of states, and partly for that reason, instead of calling them Bayesian networks, Andrew calls them hierarchical models, but they are basically the same thing. Of course, you can go further in the continuum direction and use not just some nodes with an infinite number of states, but also use graphs with an infinite number of nodes (and perhaps periodic boundary conditions).

In my 1995 paper entitled “Quantum Bayesian Nets”, I give a QB net which yields a Feynman path integral (FPI) that in turn yields the Schroedinger equation for a single mass particle in an arbitrary potential. My proof is a simple adaptation of a proof that I learned from the Feynman & Hibbs book “Quantum Mechanics and Path Integrals”.

It should be fairly straightforward to generalize my derivation to find a QB net for any quantum field theory that is defined in terms of a CONTINUOUS or discrete or hybrid sum over exp(i*action) (and such FPIs are really sums over PURE quantum states)

The Dutch Stallion and the Canadian Donkey

Filed under: Uncategorized — rrtucci @ 5:53 pm

The recent news (see my previous blog post) about the Dutch quantum institute QuTech partnering with Intel has reminded me of the differences between a Dutch stallion and a Canadian donkey.

Below is a picture of a Friesian stallion. According to Wikipedia “The Friesian (also Frisian) is a horse breed originating in Friesland, in the Netherlands” It’s a reasonable analogue of QuTech

Friesian Stallion (image from Wikipedia, here

Friesian Stallion (image from Wikipedia, here)

Next, let me show you a picture of the Donkey from the Shrek movies, which some say originated in Canada. It reminds me of Lazaridis’ IQC (Institute for Quantum Computing), which has spent more than $150M since it was founded in 2002, studying NMR quantum computers and quantum cryptography, both known to be dead end streets since day one.

Intel, Welcome Back, All is Forgiven

Filed under: Uncategorized — rrtucci @ 8:06 am

For many years, I have been shouting into the wind, trying to use this blog to cajole Intel corporation to join the quantum space race. Quantum computing is the natural next stage in their computer chip journey so working on it is the logical thing for them to do.

See the following two earlier blog posts of mine, where I called Intel the reluctant natural of quantum computing and I rebuked them for goofing off in the QC classroom:

But at last, my prayers have been answered. Intel announced a few days ago that it will be investing $50M over ten years in a Dutch company called QuTech. QuTech is trying to build an anyonic quantum computer of a type that I like to call the Kitaev quantum computer, because it was invented by Alexei Kitaev.

Welcome back, Intel, our prodigal son. The bells of all the QC churches of the world are ringing to welcome you:


Here are two paintings commissioned to commemorate this grand occasion:

The Prodigal Son (oil on canvas), Guercino (Giovanni Francesco Barbieri) (1591-1666) / Galleria Borghese, Rome, Italy

One cannot over-estimate the importance of this news to quantum computing. It’s true that $50M is pocket change for Intel, a corporation that had a revenue of $56B in 2014 and that has 100K employees. A company that is used to spending on the order of $5B on a single microchip fab. But the $50M figure doesn’t matter much. What is more important is that they have finally taken the plunge into quantum space, and that they have committed their considerable manpower and engineering expertise to help finish building the Kitaev QC. And that expertise of theirs is ideally suited for the task at hand. And Intel is not a procrastinator or faker like most academics. When Intel promises, it delivers.

Intel, be forewarned: once in, in forever. There is no known cure for quantum mechanics addiction.

Intel is the 800 pound gorilla of the microchip world. Since they built the world’s first commercial microprocessor chip in 1971, they have been one of the biggest developers and manufacturers of chips for personal computers. So here is a photo of Tarzan welcoming Intel back

(came from here), “A Mother’s Strength: Kala and Tarzan”
by Penultimate-21

and a photo of Jane Goodall welcoming Intel back:


The Intel $50M news follows on the heels of another big investment in QuTech. Indeed, 3 months ago the news media reported that QuTech has been promised $150M over ten years by the Dutch government. And Microsoft has already been investing in QuTech since 2010 or earlier. So this QuTech is a strange socialist monster, a private multinational corporation that is subsidized by the Dutch state and has very close ties to TU (Technical Univ.) Delft, another Dutch private/public hybrid. (Okay, I was joking with the above QuTech link. Here is a link to the true Dutch QuTech)
