Welcome to BayesForge, a free service on the Amazon cloud

Filed under: Uncategorized — rrtucci @ 7:08 am

Our company artiste-qb.net is proud to announce BayesForge (BF), our new service on AWS (Amazon Web Services). BayesForge is not yet open for business but will open in a week or less. The purpose of this blog post is to give an overview and teaser of what is coming.

Henning Dekant will give a tour of BF to those who attend the meeting on April 21 of the Toronto Quantum Computing Meetup.

Why AWS?

The Amazon cloud is one of the largest and Amazon offers an incredible deal to all its customers. Anybody with a credit card can get an AWS Free Tier account. An AWS Free Tier account gives you one full year of free cloud use (there are some upper bounds on usage but very generous ones). Furthermore, you can open a separate AWS Free Tier account in the name of your spouse and each of your children. Amazon doesn’t seem to care!! Only Jeff Bezos could be so crazy generous. Once you have an AWS Free Tier account, you can use it to play with BayesForge for a whole year, free of charge. You don’t have to be a student to do this.

What can you do with BayesForge?

BF allows you to write Jupyter notebooks on your web browser in a wide variety of languages and run/store those notebooks on the cloud. (Besides the web browser, no additional software needs to be installed on your computer). We have installed Jupyter kernels for Python-3, Python-2, R, Octave (clone of matlab) and bash. This means you can write/run a notebook in which you use one of those languages exclusively. We have also installed Rmagic and Octavemagic which allows you to write a notebook in Python but dip temporarily into R or Octave.

What software packages does BayesForge include?

BF comes with 2 folders called “Classical” and “Quantum”. The “Quantum” folder contains a large selection of open source quantum computing software, including our own Quantum Fog and Qubiter, and also open source qc software from DWave, IBM, Rigetti, etc. The “Classical” folder contains a large selection of open source software for doing classical bayesian statistical analysis.

Reaching Quantum Escape Velocity

Filed under: Uncategorized — rrtucci @ 5:42 pm

The term “Reaching Quantum Supremarcy”, coined by John Preskill, is usually used to refer to the first time a quantum computer can perform in minutes a calculation that would take the best classical computers centuries to perform. I prefer to call that “Reaching Quantum Escape Velocity”.

I love the term “Quantum Supremacy” too, but I like to use it differently, as in “Google, IBM and Microsoft are vying for Quantum Supremacy”, viz., to dominate the qc market. This second meaning is the one being used in my upcoming movie entitled “Quantum Supremacy”.

I prepared the following poster to promote the concept of reaching quantum escape velocity. It recycles some art from a previous blog post of mine.

Tao Yin teleports (the old fashioned way) 2 entangled cats from Germany to China

Filed under: Uncategorized — rrtucci @ 5:11 pm

In this photo you can see Tao Yin at the Frankfurt airport, before boarding an airplane to China, transporting cat #1. Cat #2 was teleported by his wife on same flight. One small pet per passenger allowed. Cats 1 and 2 are friends that were entangled at a distance during the flight.

Dr. Tao Yin obtained a Ph.D. in Physics at the end of last year from
The Goethe University in Frankfurt. He started at artiste-qb.net as a long-distance intern last summer, but he is now CTO and part owner of artiste-qb.net . He has quickly become an important part of our company. He has just moved from Frankfurt-Germany to Shenzhen-China, where he will continue to represent us. Shenzhen, population ~ 11 million, is one of the 5 largest cities in China, a technology power house located immediately north of Hong Kong.

Tao brings to artiste-qb.net excellent computer skills and knowledge of physics. We are also relying on him to translate to Mandarin Chinese some of our software docs. For example, he translated the Jupyter notebooks quantum_compiler_intro.ipynb to quantum_compiler_intro_CN.ipynb. These jupyter notebooks explain how to use the quantum compiler in our open source software Qubiter. Qubiter has had a fully-functional quantum compiler since the first week of Jan of 2017. Currently, Qubiter is the only software to offer a quantum compiler of this kind.

April the Giraffe has Baby

Filed under: Uncategorized — rrtucci @ 6:32 pm

Today, April the Giraffe had a baby boy calf after 15 months of taxing pregnancy, the progress of which has been anxiously followed via webcam by millions of animal lovers throughout the world. April lives at the Animal Adventure Park near Binghamton, NY, although conservative rumor mills claim that her real birth certificate is from Kenya.

To congratulate April and hubby Oliver on the new addition to their family, we have sent them a baby bib (size=”giraffe”), a baby bottle and a copy of our latest book “Quantum Computer Programming for Giraffes” printed on paper made from tasty Acacia tree leaves that were made-in-America.

We here at artiste-qb.net are passionate animal lovers and have a long tradition of sending gifts to giraffes and other mammals, including the least noble ones. For example, on a previous occasion, we sent to Jack Ma (founder of Alibaba) one of our stylish baseball caps, and to the new baby of Mark Zuckerberg a copy of our book “How to program the Facebook quantum computer with QuPy”. (You too can have a copy of these items for a very reasonable price. They are especially popular with people who want to make an impression at Silicon Valley cocktail parties).

Betting the farm on Rigetti Spaghetti

Filed under: Uncategorized — rrtucci @ 7:40 pm

#ElvisSighting #SteveJobsSighting

Steve Jobs and/or his Reality Distortion Field is still alive!!!

Rigetti is a quantum computer company that started about 3 years ago with an initial seed funding of $2.5M. Two days ago, the press revealed that an additional whopping $64M has been invested in the company. The company is named Trump Rigetti after its founder Chad Rigetti. Sorry but rigetti is not a new kind of macaroni. “il rigetti” actually means “he discards” in Italian.

Unlike our company artiste-qb.net which does only qc software (and also quantum ready classical software), Rigetti does mostly qc hardware (gate model, superconducting qubits). They intend to offer access to their machine via the cloud, something that DWave and IBM already do, but which slow-poke Google doesn’t do yet, although they are probably months away from doing it to keep up with the Joneses.

Although a $64M investment in qc is good news for artiste-qb.net because a rising tide raises all boats, I advise you not to invest your pension on this one. I consider it a very risky investment for the following reasons.

As far as I know, team Rigetti has yet to publish performance results for their hardware and thus subject their machine to scientific scrutiny the way Martinis at Google has amply done. (Team Rigetti did publish one paper https://arxiv.org/abs/1703.04613 on Mar 15, two weeks ago, but that paper is only about a single qubit and getting 2 qubits to interact in an ideal way is much more difficult).

Alibaba, Google, IBM, Intel, and Microsoft (alphabetical order) , not to mention the govs. of Australia, Canada, China, EU, Holland, UK and USA are each spending tens of millions of dollars per year to achieve the same goal as Rigetti, to build an elusive gate model quantum computer.

Silicon Valley is like a Republican echo chamber: a small, outlier perturbation can snowball in a hurry. Furthermore, the master-minds at Silicon Valley often try to grow their companies in a hurry hoping that these quickly become near monopolies that are too big to fail. That might work for a service company like Uber, but it might not work in the case of a company racing against some of the biggest nations and companies of the world, trying to build/invent a very NOVEL device. In this case, the company is strictly accountable to Mother Nature, and she might not favor it.

BNT and PNL, two masterpieces of Bayesian Networks retro-art

Filed under: Uncategorized — rrtucci @ 8:58 pm

An update on the latest adventures of our company artiste-qb.net.

In previous blog posts, I waxed poetic about Marco Scutari’s open source software called bnlearn for learning the structure of bnets (Bayesian networks) from data. bnlearn is written in the language R whereas Quantum Fog is written in Python. But by using Jupyter notebooks with Rmagic installed, we have been able to write some notebooks running both QFog and bnlearn side by side in the same notebook for the same bnets, and to compare outputs of both programs. That is a good bench-marking exercise for the bnet learning side of QFog, but what about it’s bnet inference side?

Two open source programs that are very good at doing bnet inference (and many other things too) are BNT (Bayes Net Toolbox, by Kevin Murphy et al) and OpenPNL (PNL = Probabilistic Networks Library, written by Intel. I like to call it PaNeL to remember the letters quickly).

So our next adventure is to learn how to use BNT and PNL and to compare them to QFog.

BNT is written in Matlab. PNL is written in C++ but it includes Matlab wrappers for most of its functions. Both BNT and PNL are very mature and comprehensive programs. Since its core is written in C++ rather than Matlab, we expect PNL to be much faster than BNT for large networks.

As you already know if you’ve ever checked Matlab’s pricing, the software is very costly for everyone except students. However, this is one case when the open source gods have listened to our prayers. Octave is a free, open source program that can run 99% of a Matlab program and the few differences between Matlab and Octave (mostly in the plotting packages) are well documented. Furthermore, one can run Octave in a Jupyter notebook, either on an Octave kernel or on a Python kernel with octavemagic (oct2py) installed.

So in order to compare QFog to bnlearn, we’ve had to start using Jupyter notebooks on R kernel  or on Python kernel with Rmagic. And in order to compare QFog with BNT&PNL, we’ve had to start using Jupyter notebooks on Octave kernel or on Python kernel with octavemagic. We have seen the light and we are now believers in a holy trinity of computer languages (diversity and open source is our strength, Mr Trump):

Python, R, Octave
(our polyglot notebooks)

Curiously, Duke Univ. offers a course called “Computational Statistics in Python” that also advocates the use of Jupyter notebooks, and the languages Python, R and Matlab intermixed to do statistics. So when two cultures independently come up with the same idea, it’s probably a good one, don’t you think?

Since BNT is written in Matlab, running it does not require any compilation. PNL, on the other hand, is written in C++, so it does. Compiling PNL has proven a difficult task because the software is ten years old, but, after a lot of sweat and tears, our wiz Henning Dekant has managed to compile it (a few issues remain).

BNT was last changed in a bigly way circa 2007 (or even earlier) and PBL on 2006. (bnlearn, by comparison, is still very active). BNT and PNL belong to what I like to call the first bnet revolution (inference by junction tree) whereas bnlearn belongs to the second revolution (structure learning from Markov blankets). Even though PNL belongs to the first, not second, revolution, it is a major mystery to me why Intel abandoned it. PNL is a very impressive, large and mature piece of software. A lot of work, love and passion seems to have gone into it. Then sometime in mid 2006, it seems to have been abandoned in a hurry, and now it looks like a ghost town, or the deserted island in the video game Myst. I already know how the game Myst ends. If anyone knows why Intel stopped PNL development circa 2006, I would appreciate it if you would tell me, either in public in this blog or in private by email. Luckily, Intel had the wisdom to make PNL open source. PNL will go on, because 💍OPEN SOURCE IS FOREVER💍.

Sorry for the length of this blog post (almost as long as a Scott Aaronson blog post or a never ending New Yorker article).

Quantum Fog’s weight in bnlearn units

Filed under: Uncategorized — rrtucci @ 2:42 am

In a recent blog post entitled “R are Us. We are all R now”, I expressed my great admiration for the R statistical computer language, and I announced the addition to the Quantum Fog (QFog) GitHub repository of a Jupyter notebook called “Rmagic for dummies” which explains how something called Rmagic allows one to run both Python and R in the same Jupyter notebook.

In 2 other earlier blog posts, I also expressed great admiration for something else, bnlearn, an open source computer program written in R by Marco Scutari for learning classical Bayesian networks (cbnets) from data. I consider bnlearn the gold standard of bnet learning software.

The main purpose of this blog post is to announce that the QFog GitHub repo now has a folder of Jupyter notebooks comparing QFog to bnlearn. This is a perfect application of Rmagic to comparing two applications that can do some of the same things but one app is written in R while the other is written in Python. Pitting QFog against bnlearn is highly beneficial to us developers of QFog because it shows us what needs to be improved and suggests new features that would be worthwhile to add.

QFog can do certain things that bnlearn can’t (most notably, QFog can do both classical and quantum bnets, whereas bnlearn can only do classical bnets), and vice versa (for instance, bnlearn can do bnets with continuous (Gaussian) node probability distributions, whereas QFog can only handle discrete PDs), but there is much overlap between the 2 software packages in the area of structure and parameter learning of classical bnets from data.

A cool feature of the folder of Jupyter notebooks comparing bnlearn and QFog is that most notebooks in that folder can be spawned and run from a single “master” notebook. This amazing ability of the “master” notebook to create and direct a zombie horde of other notebooks is achieved thanks to an open source Python module called “nbrun” (notebook run).

Quantum-Ready Software

Filed under: Uncategorized — rrtucci @ 12:26 am

Quantum Fog is “quantum-ready” software: it has a parameter “is_quantum” in many of its functions which allows you to switch between Classical Bayesian Networks (is_quantum=False) and Quantum Bayesian Networks (is_quantum=True)
quantum-switch.jpg

(footnote) I am not the first to use the term “quantum-ready”. I first heard it used by Henning Dekant. A Google search conducted before writing this blog post led me to discover that the company 1Qbit has also used this term in the past in its promotional literature

R are us. We are all R now.

Filed under: Uncategorized — rrtucci @ 5:08 pm

I have long been an enthusiastic proponent of R, a computer language designed for doing statistical analysis. In fact, 7 years ago I wrote a post in this blog entitled “Addicted to R”.

Our company (artiste-qb.net) has been publishing software written mostly in Python. The Python ecosystem includes a very nice statistical package called Pandas, whose authors profess much love for R and unabashedly admit that they were trying to copy the best of R’s statistical functionality and bring it to Python users. This is fine and good, but is not enough, is it?

R has been around for a long time (since 1993 according to Wikipedia), and during that time it has managed to accumulate a formidable number of highly useful extension packages and a very large and passionately committed community of fans. As good as Pandas is, it would be a pity and outright foolish if our company and others in the same boat ignored R’s rich libraries and numerous users.

So I was elated when Tao Yin, a member of our company, introduced our company members to rpy2 and its extension Rmagic. Rmagic allows one to invoke R functions inside a Jupyter notebook running with a Python kernel. So in a single Jupyter notebook, you can call both Python functions and R functions in the same cell, or have some cells running just R and others running just Python. And of course, variables can be exchanged easily between R and Python within that notebook. So we are all R now. And Python too.

I’ve only known about Rmagic for about a week so I’m a newbie at it. Fortunately, even though rpy2/Rmagic is very sophisticated software under the hood, it’s API (Application Programming Interface) is quite simple and intuitive. I wrote a Jupyter notebook called “Rmagic for dummies” that I hope will convince you that Rmagic is very powerful yet easy to use.

The Bizarre History of Cambridge Quantum Computing (CQC Ltd)

Filed under: Uncategorized — rrtucci @ 7:44 pm

Cambridge Quantum Computing (CQC) is a very British startup in the field of quantum computer software with a short but bizarre history that I find humorous. A case of fact being funnier than fiction.

CQC was founded in 2015 by Ilyas Khan. According to the Wikipedia article on Ilyas, which was probably written by himself, he comes to the QC business with no scientific degrees or programming experience of any kind. His training and experience are mostly in investment banking and philosophy. Here are some excerpts from the Wikipedia article:

“Khan is a merchant banker by training and started his career at the London firm of J. Henry Schroder Wagg & Co. Ltd. He was also the owner of the famous English football team Accrington Stanley and is its Patron [2] and the founder and publisher of the Asia Literary Review.[3]”

“His special interests include philanthropy and Wittgenstein, and he is a member of the British Wittgenstein Society.”

“Khan has lectured and published papers on Ludwig Wittgenstein, among other subjects.”

“In 2015 Khan founded Cambridge Quantum Computing,[5] which was selected by Bloomberg L.P., as a business Innovator 2016,[6] he has also published on the subject of Quantum Information Processing [7]”

Apart from having a warm & fuzzy feeling for quantum subjects, it’s not clear that Khan understands the underpinnings of QC enough to lecture about it or lead a QC software company prudently.

I first learned about CQC when the press went crazy over the news that a Chilean investment group called Grupo Arcano led by Alberto Chang Rajii was going to invest $50 million in CQC. For instance, here is an article by Bloomberg announcing this:

Early Google Investor to Help Bring Quantum Computing to Markets (by John Detrixche, Aug 26, 2015, Bloomberg news)

The importance of Alberto Chang to CQC was quickly confirmed by his ascension to the top spot in the “Team” webpage of the CQC website. Here is that page on Mar 4, 2016, retrieved using the WayBack machine. Click to enlarge.

cqc-team-mar-4-2016

All mention of Alberto Chang has disappeared from the latest reincarnations of the CQC “Team” webpage. What happened?

Well, if you google “Alberto Chang” “pyramid scheme”, you will find lots of news articles in English about Chang. (Or if you know Spanish, google the key words: Alberto Chang Rajii estafa)

For most of his career as a VC fund manager, Chang had been claiming that he had a business degree from Stanford, and that while at Stanford, he had met Sergey Brin and Larry Page, and had been one of the first investors in Google, an investment that had earned him millions. But Stanford and the founders of Google have now denied these assertions and Chang has been forced to recant publicly.

Grupo Arcano is (or was) based in Chile, with offices in Santiago-Chile, Miami-USA, London-UK and Sydney-Australia. Chang fled Chile to Malta on April 2016. He is a fugitive of the Chilean Law, which accuses him of running a pyramid scheme. His mother, a cofounder of Grupo Arcano, also tried to flee Chile but was snagged at the airport and is now under house arrest in Chile. Chang was seeking asylum in Malta but the Maltese government ultimately denied it and he awaits extradition to Chile. Chang’s assets have been frozen in the US and Europe, and the U.S. Securities and Exchange Commission has recently announced fraud charges against him.

Meanwhile, CQC continues chugging along. I just saw on Twitter that Khan is scheduled to give the keynote speech at some posh UK tech conference.

Qubiter and IBM-QASM2 can now communicate via sign language

Filed under: Uncategorized — rrtucci @ 5:15 pm

I’ve always liked mime (Marcel Marceau, Charlie Chaplin,…), physical comedy (using body motions as a source of humor, like Italians do) and the closely related sign-language for the deaf. Sign language can be extremely clever, inventive and expressive. For example, this is how to say Donald Trump in sign-language:
trump-in-sign-language

But enough about Trump, who threatens to suck the air and joy out of every conversation. The official purpose of this blog post is to advertise the fact that now Qubiter (https://github.com/artiste-qb-net/qubiter) can convert quantum circuits from its native language to that of IBM, so that you can generate quantum circuits using Qubiter and then run them on the IBM hardware (assuming that those circuits have only 5 qubits and less than about 80 gates)

Recently, the folks at IBM Quantum Experience (IBM-QE) have introduced some very nice enhancements to their QC cloud service. The graphical user interface (GUI) of their website has been revamped. They have also opened two new repositories on GitHub,

  1. IBMQuantum/QASM
  2. IBMResearch/python-sdk-quantum-experience

Repo 1 introduces their new “intermediate level language” QASM2.0 with a paper in Latex/pdf that teaches the in and outs of their language. This repo also includes samples of qasm2 scripts of two types: some that can be run on their current hardware, and some that can’t be but can still be simulated using their numerical simulator.

Repo 2 gives some Python code for accessing the IBM-QE service via a python script or Jupyter notebook.

To keep up with these IBM enhancements, Qubiter now includes a new file called Qubiter_to_IBMqasm.py This file contains a class of the same name that translates Qubiter “English files” to IBM QASM files. You can write a simple Python script that reads the qasm file produced by the class Qubiter_to_IBMqasm and inputs that string into the code of Repo 2. That way, you don’t even have to visit the IBM-QE website to run your q circuit on their hardware. Alternatively, you can manually copy&paste the qasm file produced by the new Qubiter class into the “QASM Editor” at the IBM-QE website.

The current IBM-QE hardware doesn’t allow all possible CNOTs among its 5 qubits. Out of the 5 qubits 0, 1, …, 4, only qubits 1, 2 and 4 can be physical targets of an elementary CNOT. Also, some pairs of qubits cannot be the two ends of an elementary CNOT because they are physically disconnected. The class Qubiter_to_IBMqasm overcomes both of these limitations. It allows CNOTs among any pair of qubits. Every elementary CNOT that is disallowed is replaced by a compound CNOT; i.e., either 1 or 4 elementary CNOTs (and a bunch of Hadamards) that is equivalent to the original CNOT and is allowed.

Microsoft Quantum Computing Olympics QIP2017 Comes to A Close Today

Filed under: Uncategorized — rrtucci @ 8:16 pm

Today was an ominous day for the Galaxy. QIP2017 came to a close and Donald Trump was inaugurated as president of the United States…


Today, attendees of QIP2017 got these two postcards with an attached note saying: “Microsoft bids you a fond farewell and would like you to have these 2 commemorative postcards as a final bit of swag to remember QIP2017”

A photograph of a dangerous thug

Filed under: Uncategorized — rrtucci @ 2:51 am

The purpose of this post is to remind my readers of Microsoft’s thuggish history, as described by the NYT. Will Microsoft be a repeat offender in the emerging field of quantum computing? IMHO, there are some ominous signs that it has started to move full-steam in that direction.

Check out this great article:

MICROSOFT’S WORLD: A special report.; How Software’s Giant Played Hardball Game,By Steve Lohr and John Markoff, New York Times, Oct 8, 1998

Next I will quote the beginning of the article. I recommend that you read the whole thing. The article doesn’t tell the half of it. For example, it doesn’t describe Microsoft’s vigorous attempts to destroy Linux OS and the open software movement. And any company that posed the smallest threat to its Office suite of apps.

In the summer of 1995, a whiff of revolution was in the air in Silicon Valley. The Internet offered a new deal in computing, a fresh opportunity for entrepreneurs to try to break the Microsoft Corporation’s firm grip on the personal computer software business. Leading the challenge was the Netscape Communications Corporation, whose software for browsing the World Wide Web had ignited the Internet boom.

James H. Clark, Netscape’s chairman, spoke boldly of attacking Microsoft head-on. He borrowed imagery from the movie ”Star Wars,” referring to Microsoft as the Death Star and Netscape as the leader of a rebel alliance.

Microsoft answered with a vengeance. It dispatched hundreds of programmers to work on a competing browser and poured many millions of dollars into marketing it. It prodded computer makers and others to distribute its browser, folded the browser into its industry-dominant Windows operating system and gave the browser away free — a campaign intended to ”cut off their air supply,” as a senior Microsoft executive described it.

But it’s not only competitors like Netscape that have encountered Microsoft’s force. Microsoft’s partners, its corporate customers and professional investors who finance new ventures have all collided with it.

A close look at Microsoft’s no-holds-barred push into the Internet software business offers a window into the ways the company uses its market muscle to influence the behavior of virtually every player in the industry.

Some of the cases recounted here figure prominently in the suit brought by the Justice Department and 20 states, scheduled to go to trial later this month, charging that Microsoft at times went too far — and violated antitrust laws.

Regardless of the legal outcome, previously unreported details about incidents in the suit and the other examples provide a more complete picture of Microsoft in action.

*When the Compaq Computer Corporation considered loading Netscape’s browser instead of Microsoft’s on its machines, Microsoft threatened to stop selling its Windows operating system to the big personal computer maker. Compaq, Microsoft’s largest customer in the industry, quickly changed its mind.

*After Spyglass Inc. began supplying Microsoft with its early browser technology, Microsoft announced that it would give away its browser free. The timing came as a rude surprise to its partner Spyglass. The company lost most of its revenues almost overnight, as the technology, which it had also been licensing to companies besides Microsoft, suddenly became available free.

QIP2017 is next week

Filed under: Uncategorized — rrtucci @ 3:15 am

As I mentioned in my previous post, the QIP2017 conference will be held on Jan 16-20, 2017 at Microsoft HQ, the geometrical center of the DeathStar.

One cannot help noticing that Google, despite it’s considerable commitment to gate model quantum computing, did not sponsor or participate in any committees of Microsoft’s QIP2017. Was this an intentional boycott?

The quantum annealer crowd (DWave, NASA, Lockheed-Martin) has stayed away from QIP2017 too, except for a tiny company called 1Qbit. I do not include Google in that crowd because Google, despite what it seemed to claim when it first hired Martinis, seems to have abandoned quantum annealers to pursue gate model QCs almost exclusively.

All talks at QIP are summaries of papers that have been posted at arXiv months ago, so this conference is an academic version of a pre-scripted American political convention and an ad for MS. If you are not already aware of this, many if not most academic researchers are politicians (some very eager to be bought) first and researchers second. Since the papers have been available to anyone for months, any researcher needing to ask questions to the authors could have done so long ago at almost no cost via email or video conferencing. So it’s hard to justify the cost incurred by the researchers to attend such conventions (entrance fee ~ $400 + airplane fare + hotel costs, all courtesy of the taxpayer for NSF funded researchers)

Here are some materials that MS is circulating to promote the event. MS intends to use the occasion to show to the world the superiority of the MS race in quantum computing.
